Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Summary
China’s actions for asserting and defending its maritime territorial and exclusive economic zone
(EEZ) claims in the East China (ECS) and South China Sea (SCS), particularly since late 2013,
have heightened concerns among observers that ongoing disputes over these waters and some of
the islands within them could lead to a crisis or conflict between China and a neighboring country
such as Japan, the Philippines, or Vietnam, and that the United States could be drawn into such a
crisis or conflict as a result of obligations the United States has under bilateral security treaties
with Japan and the Philippines.
More broadly, China’s actions for asserting and defending its maritime territorial and EEZ claims
have led to increasing concerns among some observers that China may be seeking to dominate or
gain control of its near-seas region, meaning the ECS, the SCS, and the Yellow Sea. Chinese
domination over or control of this region, or Chinese actions that are perceived as being aimed at
achieving such domination or control, could have major implications for the United States,
including implications for U.S.-China relations, for interpreting China’s rise as a major world
power, for the security structure of the Asia-Pacific region, for the long-standing U.S. strategic
goal of preventing the emergence of a regional hegemon in one part of Eurasia or another, and for
two key elements of the U.S.-led international order that has operated since World War II—the
non-use of force or coercion as a means of settling disputes between countries, and freedom of
the seas.
China is a party to multiple territorial disputes in the SCS and ECS, including, in particular,
disputes over the Paracel Islands, Spratly Islands, and Scarborough Shoal in the SCS, and the
Senkaku Islands in the ECS. China depicts its territorial claims in the SCS using the so-called
map of the nine-dash line that appears to enclose an area covering roughly 90% of the SCS. Some
observers characterize China’s approach for asserting and defending its territorial claims in the
ECS and SCS as a “salami-slicing” strategy that employs a series of incremental actions, none of
which by itself is a casus belli, to gradually change the status quo in China’s favor. At least one
Chinese official has used the term “cabbage strategy” to refer to a strategy of consolidating
control over disputed islands by wrapping those islands, like the leaves of a cabbage, in
successive layers of occupation and protection formed by fishing boats, Chinese Coast Guard
ships, and then finally Chinese naval ships.
In addition to territorial disputes in the SCS and ECS, China is involved in a dispute, particularly
with the United States, over whether China has a right under international law to regulate the
activities of foreign military forces operating within China’s EEZ. The dispute appears to be at
the heart of incidents between Chinese and U.S. ships and aircraft in international waters and
airspace in 2001, 2002, 2009, and 2013.
The U.S. position on territorial and EEZ disputes in the Western Pacific (including those
involving China) includes the following elements, among others: The United States takes no
position on competing claims to sovereignty over disputed land features in the ECS and SCS.
Claims of territorial waters and EEZs should be consistent with customary international law of
the sea and must therefore, among other things, derive from land features. Claims in the SCS that
are not derived from land features are fundamentally flawed. Territorial disputes should be
resolved peacefully, without coercion, intimidation, threats, or the use of force. Parties should
avoid taking provocative or unilateral actions that disrupt the status quo or jeopardize peace and
security; the Senkaku Islands are under the administration of Japan and unilateral attempts to

change the status quo raise tensions and do nothing under international law to strengthen
territorial claims. The United States has a national interest in the preservation of freedom of seas
as recognized in customary international law of the sea. The United States opposes claims that
impinge on the rights, freedoms, and lawful uses of the sea that belong to all nations. The United
States, like most other countries, believes that coastal states under UNCLOS have the right to
regulate economic activities in their EEZs, but do not have the right to regulate foreign military
activities in their EEZs.
The situation concerning maritime territorial and EEZ disputes involving China raises several
potential policy and oversight issues for Congress. Legislation in the 113th Congress concerning
maritime territorial and EEZ disputes involving China in the SCS and ECS includes H.R. 4435/S.
2410 (the FY2015 National Defense Authorization Act), H.R. 4495, H.R. 772, S.Res. 412, and
S.Res. 167.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Introduction
China’s actions for asserting and defending its maritime territorial and exclusive economic zone
(EEZ)1 claims in the East China (ECS) and South China Sea (SCS), particularly since late 2013,
have heightened concerns among observers that ongoing disputes over these waters and some of
the islands within them could lead to a crisis or conflict between China and a neighboring country
such as Japan, the Philippines, or Vietnam, and that the United States could be drawn into such a
crisis or conflict as a result of obligations the United States has under bilateral security treaties
with Japan and the Philippines.
More broadly, China’s actions for asserting and defending its maritime territorial and EEZ claims
have led to increasing concerns among some observers that China may be seeking to dominate or
gain control of its near-seas region, meaning the ECS, the SCS, and the Yellow Sea. Chinese
domination over or control of this region, or Chinese actions that are perceived as being aimed at
achieving such domination or control, could have major implications for the United States,
including implications for U.S.-China relations, for interpreting China’s rise as a major world
power, for the security structure of the Asia-Pacific region, for the long-standing U.S. strategic
goal of preventing the emergence of a regional hegemon in one part of Eurasia or another, and for
two key elements of the U.S.-led international order that has operated since World War II—the
non-use of force or coercion as a means of settling disputes between countries, and freedom of
the seas.
The situation concerning maritime territorial and EEZ disputes involving China raises several
potential policy and oversight issues for Congress. Decisions that Congress makes on these issues
could substantially affect U.S. political and economic interests in the Asia-Pacific region and U.S.
military operations in both the Asia-Pacific region and elsewhere.
The specifics of China’s maritime territorial disputes with other countries are discussed in greater
detail in other CRS reports.2 Additional CRS reports cover other aspects of U.S. relations with
China and other countries in the region.
Background
Overview of Disputes
Maritime Territorial Disputes
China is a party to multiple maritime territorial disputes in the SCS and ECS, including in
particular the following (see Figure 1 for locations of the island groups listed below):

1 A country’s EEZ includes waters extending up to 200 nautical miles from its land territory. Coastal states have the
right under the United Nations Convention on the Law of the Sea (UNCLOS) to regulate foreign economic activities in
their own EEZs. EEZs were established as a feature of international law by UNCLOS.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

• a dispute over the Paracel Islands in the SCS, which are claimed by China and
Vietnam, and occupied by China;
• a dispute over the Spratly Islands in the SCS, which are claimed entirely by
China, Taiwan, and Vietnam, and in part by the Philippines, Malaysia, and
Brunei, and which are occupied in part by all these countries except Brunei;
• a dispute over Scarborough Shoal in the SCS, which is claimed by China,
Taiwan, and the Philippines; and
• a dispute over the Senkaku Islands in the ECS, which are claimed by China,
Taiwan, and Japan, and administered by Japan.
The island and shoal names used above are the ones commonly used in the United States; in other
countries, these islands are known by various other names. China, for example, refers to the
Paracel Islands as the Xisha islands, to the Spratly Islands as the Nansha islands, to Scarborough
Shoal as Huangyan island, and to the Senkaku Islands as the Diaoyu islands.
These island groups are not the only land features in the SCS and ECS—the two seas feature
other islands, rocks, shoals, and reefs, as well as some near-surface submerged features. The
territorial status of some of these other features is also in dispute.3 It should also be noted that
there are additional maritime territorial disputes in the Western Pacific that do not involve China.4
Maritime territorial disputes in the SCS and ECS date back many years, and have periodically led
to incidents and periods of increased tension.5 The disputes have again intensified in the past few
years, leading to numerous confrontations and incidents involving fishing vessels, oil exploration
vessels and oil rigs, coast guard ships, naval ships, and military aircraft. The intensification of the
disputes in recent years has substantially heightened tensions between China and other countries
in the region, particularly Japan, the Philippines, and Vietnam.

3 For example, the Reed Bank, a submerged atoll northeast of the Spratly Islands, is the subject of a dispute between
China and the Philippines, and the Macclesfield Bank, a group of submerged shoals and reefs between the Paracel
Islands and Scarborough Shoal, is claimed by China, Taiwan, and the Philippines. China refers to the Macclesfield
Bank as the Zhongsha islands, even though they are submerged features rather than islands.
4 North Korea and South Korea, for example, have not reached final agreement on their exact maritime border; South
Korea and Japan are involved in a dispute over the Liancourt Rocks—a group of islets in the Sea of Japan that Japan
refers to as the Takeshima islands and South Korea as the Dokdo islands; and Japan and Russia are involved in a
dispute over islands dividing the Sea of Okhotsk from the Pacific Ocean that Japan refers to as the Northern Territories
and Russia refers to as the South Kuril Islands.
5 One observer states that “notable incidents over sovereignty include the Chinese attack on the forces of the Republic
of Vietnam [South Vietnam] in the Paracel Islands in 1974, China’s attack on Vietnamese forces near Fiery Cross Reef
[in the Spratly Islands] in 1988, and China’s military ouster of Philippines forces from Mischief Reef [also in the
Spratly Islands] in 1995.” Peter Dutton, “Three Dispute and Three Objectives,” Naval War College Review, Autumn
2011: 43. A similar recounting can be found in Department of Defense, Annual Report to Congress, Military and
Security Developments Involving the People’s Republic of China

Dispute Regarding China’s Rights Within Its EEZ
In addition to maritime territorial disputes in the SCS and ECS, China is involved in a dispute,
particularly with the United States, over whether China has a right under international law to
regulate the activities of foreign military forces operating within China’s EEZ. The position of the
United States and most countries is that while the United Nations Convention on the Law of the
Congressional Research Service
3

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Sea (UNCLOS), which established EEZs as a feature of international law, gives coastal states the
right to regulate economic activities (such as fishing and oil exploration) within their EEZs, it
does not give coastal states the right to regulate foreign military activities in the parts of their
EEZs beyond their 12-nautical-mile territorial waters.6 The position of China and some other
countries (i.e., a minority group among the world’s nations) is that UNCLOS gives coastal states
the right to regulate not only economic activities, but also foreign military activities, in their
EEZs. In response to a request from CRS to identify the countries taking this latter position, the
U.S. Navy states that
countries with restrictions inconsistent with the Law of the Sea Convention [i.e., UNCLOS]
that would limit the exercise of high seas freedoms by foreign navies beyond 12 nautical
miles from the coast are [the following 27]:
Bangladesh, Brazil, Burma, Cambodia, Cape Verde, China, Egypt, Haiti, India, Iran, Kenya,
Malaysia, Maldives, Mauritius, North Korea, Pakistan, Portugal, Saudi Arabia, Somalia, Sri
Lanka, Sudan, Syria, Thailand, United Arab Emirates, Uruguay, Venezuela, and Vietnam.7
Other observers provide different counts of the number of countries that take the position that
UNCLOS gives coastal states the right to regulate not only economic activities but also foreign
military activities in their EEZs. For example, one set of observers, in an August 2013 briefing,
stated that 18 countries seek to regulate foreign military activities in their EEZs, and that three of
these countries—China, North Korea, and Peru—have directly interfered with foreign military
activities in their EEZs.8
The dispute over whether China has a right under UNCLOS to regulate the activities of foreign
military forces operating within its EEZ appears to be at the heart of incidents between Chinese
and U.S. ships and aircraft in international waters and airspace, including
• incidents in March 2001, September 2002, March 2009, and May 2009, in which
Chinese ships and aircraft confronted and harassed the U.S. naval ships
Bowditch, Impeccable, and Victorious as they were conducting survey and ocean
surveillance operations in China’s EEZ;
• an incident on April 1, 2001, in which a Chinese fighter collided with a U.S.
Navy EP-3 electronic surveillance aircraft flying in international airspace about
65 miles southeast of China’s Hainan Island in the South China Sea, forcing the
EP-3 to make an emergency landing on Hainan Island;9 and

6 The legal term under UNCLOS for territorial waters is territorial seas. This report uses the more colloquial term
territorial waters to avoid confusion with terms like South China Sea and East China Sea.

countries—Ecuador and Peru—also have restrictions inconsistent with UNCLOS that would limit the exercise of high
seas freedoms by foreign navies beyond 12 nautical miles from the coast, but do so solely because they claim an
extension of their territorial sea beyond 12 nautical miles.

EEZs.

• an incident on December 5, 2013, in which a Chinese navy ship put itself in the
path of the U.S. Navy cruiser Cowpens as it was operating 30 or more miles from
China’s aircraft carrier Liaoning, forcing the Cowpens to change course to avoid
a collision.
Figure 2 shows the locations of the 2001, 2002, and 2009 incidents listed in the first two bullets
above. The incidents shown in Figure 2 are the ones most commonly cited prior to the December
2013 involving the Cowpens, but some observers list additional incidents as well. For example,
one set of observers, in an August 2013 briefing, provided the following list of incidents in which
China has challenged or interfered with operations by U.S. ships and aircraft and ships from
India’s navy:
• USNS Bowditch (March 2001);
• EP-3 Incident (April 2001);
• USNS Impeccable (March 2009);
• USNS Victorious (May 2009);
• USS George Washington (July-November 2010);
• U-2 Intercept (June 2011);
• INS [Indian Naval Ship] Airavat (July 2011);
• INS [Indian Naval Ship] Shivalik (June 2012); and
• USNS Impeccable (July 2013).10
Regarding some of these incidents, one observer states that
the airmen and sailors of all countries know how to operate around each other in a safe
fashion. There is no lack of knowledge or training. The rules are well understood as to how
you operate your ship or your airplane so you don’t hit somebody.
What matters is the political direction given to the military. If your government says to you,
“I really want you to muscle those people. Forget about the rules. Just see if you can make
them give way.” That’s what led to the incident in 2001. That’s what led to the incident with

Relationship of Maritime Territorial Disputes to EEZ Dispute
The issue of whether China has the right under UNCLOS to regulate foreign military activities in
its EEZ is related to, but ultimately separate from, the issue of territorial disputes in the SCS and
ECS. The two issues are related because China can claim EEZs from inhabitable islands over
which it has sovereignty, so accepting China’s claims to sovereignty over inhabitable islands in

the SCS or ECS could permit China to expand the EEZ zone within which China claims a right to
regulate foreign military activities.
The EEZ issue is ultimately separate from the territorial disputes issue because even if all the
territorial disputes in the SCS and ECS were resolved, and none of China’s claims in the SCS and
ECS were accepted, China could continue to apply its concept of its EEZ rights to the EEZ that it
unequivocally derives from its mainland coast—and it is in this unequivocal Chinese EEZ that
most of the past U.S.-Chinese incidents at sea have occurred.
Press reports of maritime disputes in the SCS and ECS often focus on territorial disputes while
devoting little or no attention to the related but ultimately separate EEZ dispute. From the U.S.
perspective, however, the EEZ dispute is arguably as significant as the maritime territorial
disputes because of its potential for leading to a U.S.-Chinese incident at sea12 and because of its
potential for affecting U.S. military operations not only in the SCS and ECS, but around the
world.
1972 Multilateral Convention on Preventing Collisions at Sea
(COLREGs Convention)

China and the United States, as well as more than 150 other countries (including all those
bordering on the South East and South China Seas other than Taiwan),13 are parties to an October
1972 multilateral convention on international regulations for preventing collisions at sea,
commonly known as the collision regulations (COLREGs) or the “rules of the road.”14 Although
referred to as a set of rules or regulations, the multilateral convention is a binding treaty. The
convention applies “to all vessels upon the high seas and in all waters connected therewith
navigable by seagoing vessels.”15
In a February 18, 2014, letter to Senator Marco Rubio concerning the December 5, 2013, incident
involving the Cowpens, the State Department stated:
In order to minimize the potential for an accident or incident at sea, it is important that the
United States and China share a common understanding of the rules for operational air or
maritime interactions. From the U.S. perspective, an existing body of international rules and
guidelines—including the 1972 International Regulations for Preventing Collisions at Sea
(COLREGs)—are sufficient to ensure the safety of navigation between U.S. forces and the
force of other countries, including China. We will continue to make clear to the Chinese that
these existing rules, including the COLREGs, should form the basis for our common

understanding of air and maritime behavior, and we will encourage China to incorporate
these rules into its incident-management tools.
Likewise, we will continue to urge China to agree to adopt bilateral crisis management tools
with Japan and to rapidly conclude negotiations with ASEAN16 on a robust and meaningful
Code of Conduct in the South China in order to avoid incidents and to manage them when
they arise. We will continue to stress the importance of these issues in our regular
interactions with Chinese officials.17
In the 2014 edition of its annual report on military and security developments involving China,
the Department of Defense (DOD) states:
On December 5, 2013, a PLA Navy vessel and a U.S. Navy vessel operating in the South
China Sea came into close proximity. At the time of the incident, USS COWPENS (CG 63)
was operating approximately 32 nautical miles southeast of Hainan Island. In that location,
the U.S. Navy vessel was conducting lawful military activities beyond the territorial sea of
any coastal State, consistent with customary international law as reflected in the Law of the
Sea Convention. Two PLA Navy vessels approached USS COWPENS. During this
interaction, one of the PLA Navy vessels altered course and crossed directly in front of the
bow of USS COWPENS. This maneuver by the PLA Navy vessel forced USS COWPENS to
come to full stop to avoid collision, while the PLA Navy vessel passed less than 100 yards
ahead. The PLA Navy vessel’s action was inconsistent with internationally recognized rules
concerning professional maritime behavior (i.e., the Convention of International Regulations
for Preventing Collisions at Sea), to which China is a party.18
2014 Code For Unplanned Encounters At Sea (CUES)
On April 22, 2014, representatives of 21 Pacific-region navies (including China, Japan, and the

The Western Pacific Naval Symposium (WPNS) comprises navies whose countries border the
Pacific Ocean region. It was inaugurated in 1988 after navy chiefs attending the International
Seapower Symposium in 1987 agreed to establish a forum where leaders of regional navies could
meet to discuss cooperative initiatives. Under the WPNS, member countries convene biennially to
discuss regional and global maritime issues.
As of October 2010, WPNS membership stands at 20 members and four observers. They are:
Members: Australia, Brunei, Cambodia, Canada, Chile, France, Indonesia, Japan, Malaysia, New
Zealand, Papua New Guinea, People’s Republic of China, Philippines, Republic of Korea, Russia,
Singapore, Thailand, Tonga, United States of America and Vietnam
Observers: Bangladesh, India, Mexico and Peru

non-binding agreement, establishes a standardized protocol of safety procedures, basic
communications and basic maneuvering instructions for naval ships and aircraft during unplanned
encounters at sea, with the aim of reducing the risk of incidents arising from such encounters.20
Two observers stated that “The resolution is non-binding; only regulates communication in
‘unplanned encounters,’ not behavior; fails to address incidents in territorial waters; and does not
apply to fishing and maritime constabulary vessels, which are responsible for the majority of
Chinese harassment operations.”21 An April 23, 2014, press report stated:
Beijing won't necessarily observe a new code of conduct for naval encounters when its ships
meet foreign ones in disputed areas of the East and South China seas, according to a senior
Chinese naval officer involved in negotiations on the subject....
U.S. naval officers have said they hoped all members of the group would observe the code in
all places, including waters where China’s territorial claims are contested by its neighbors.
But the code isn’t legally binding, and it remains to be seen whether China will observe it in
what the U.S. sees as international waters and Beijing sees as part of its territory.
Senior Capt. Ren Xiaofeng, the head of the Chinese navy’s Maritime Security/Safety Policy
Research Division, said that when and where the code was implemented had to be discussed
bilaterally between China and other nations, including the U.S.
“It’s recommended, not legally binding,” Capt. Ren told The Wall Street Journal....22
Another observer states that China
touts the fact that it recently signed a Code for Unplanned Encounters at Sea at the recent
Western Pacific Naval Symposium held in Qingdao. CUES is meant to help avoid accidents
at sea. However, the code is voluntary and applies only when naval ships and aircraft meet
“casually or unexpectedly.” It also does not apply to a country’s territorial waters, and of

course countering China’s expansive claims to territorial waters is one of the most pressing
problems in the South and East China Seas.23
Negotiations Between China and ASEAN on SCS Code of Conduct
In 2002, China and the 10 member states of ASEAN signed a non-binding Declaration on the
Conduct (DOC) of Parties in the South China Sea in which the parties, among other things,
... reaffirm their respect for and commitment to the freedom of navigation in and overflight
above the South China Sea as provided for by the universally recognized principles of
international law, including the 1982 UN Convention on the Law of the Sea....
... undertake to resolve their territorial and jurisdictional disputes by peaceful means, without
resorting to the threat or use of force, through friendly consultations and negotiations by
sovereign states directly concerned, in accordance with universally recognized principles of
international law, including the 1982 UN Convention on the Law of the Sea....
... undertake to exercise self-restraint in the conduct of activities that would complicate or
escalate disputes and affect peace and stability including, among others, refraining from
action of inhabiting on the presently uninhabited islands, reefs, shoals, cays, and other
features and to handle their differences in a constructive manner....
...reaffirm that the adoption of a [follow-on] code of conduct in the South China Sea would
further promote peace and stability in the region and agree to work, on the basis of
consensus, towards the eventual attainment of this objective....24
In July 2011, China and ASEAN adopted a preliminary set of principles for implementing the
DOC. U.S. officials since 2010 have encouraged ASEAN and China to develop the follow-on
binding Code of Conduct (COC) mentioned in the final paragraph above. China and ASEAN
have conducted negotiations on the follow-on COC, but China has not yet agreed with the
ASEAN member states on a final text. An August 5, 2013, press report states that “China is in no
rush to sign a proposed agreement on maritime rules with Southeast Asia governing behavior in
the disputed South China Sea, and countries should not have unrealistic expectations, the Chinese
foreign minister said on Monday [August 5].”25
China’s Approach to Maritime Territorial Disputes
Map of the Nine-Dash Line
China depicts its territorial claims in the SCS using the so-called map of the nine-dash line—a
Chinese map of the SCS showing nine line segments that, if connected, would enclose an area
covering roughly 90% (earlier estimates said about 80%) of the SCS (Figure 3).

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

The area inside the nine line segments far exceeds what is claimable as territorial waters under
customary international law of the sea as reflected in UNCLOS, and, as shown in Figure 4,
includes waters that are within the claimable EEZs (and in some places are quite near the coasts)
of the Philippines, Malaysia, Brunei, and Vietnam.
Figure 4. EEZs Overlapping Zone Enclosed by Map of Nine-Dash Line

Source: Source: Eurasia Review, September 10, 2012.
Notes: (1) The red line shows the area that would be enclosed by connecting the line segments in the map of
the nine-dash line. Although the label on this map states that the waters inside the red line are “China’s claimed
territorial waters,” China has maintained ambiguity over whether it is claiming full sovereignty over the entire
area enclosed by the nine line segments. (2) The EEZs shown on the map do not represent the totality of
maritime territorial claims by countries in the region. Vietnam, to cite one example, claims all of the Spratly
Islands, even though most or all of the islands are outside the EEZ that Vietnam derives from its mainland coast.
The map of the nine-dash line, also called the U-shaped line or the cow tongue,26 predates the
establishment of the People’s Republic of China (PRC) in 1949. The map has been maintained by
the PRC government, and maps published in Taiwan also show the nine line segments.27 In a

26 The map is also sometimes called the map of the nine dashed lines (as opposed to nine-dash line), perhaps because
some maps (such as Figure 3) show each line segment as being dashed.

document submitted to the United Nations on May 7, 2009, that included the map as an
attachment, China stated:
China has indisputable sovereignty over the islands in the South China Sea and the adjacent
waters, and enjoys sovereign rights and jurisdiction over the relevant waters as well as the
seabed and subsoil thereof (see attached map [of the nine-dash line]). The above position is
consistently held by the Chinese Government, and is widely known by the international
community.28
The map does not always have exactly nine dashes. Early versions of the map had as many as 11
dashes, and a new map of China published by the Chinese government in June 2014 includes 10
dashes.29
China has maintained some ambiguity over whether it is using the map of the nine-dash line to
claim full sovereignty over the entire sea area enclosed by the nine-dash line, or something less
than that.30 Maintaining this ambiguity can be viewed as an approach that preserves flexibility for
China in pursuing its maritime claims in the SCS while making it more difficult for other parties
to define specific objections or pursue legal challenges to those claims. It does appear clear,
however, that China at a minimum claims sovereignty over the island groups inside the nine line
segments—China’s domestic Law on the Territorial Sea and Contiguous Zone, enacted in 1992,
specifies that China claims sovereignty over all the island groups inside the nine line segments.31
China’s implementation on January 1, 2014, of a series of fishing regulations covering much of
the SCS suggests that China claims at least some degree of administrative control over much of
the SCS.
“Salami-Slicing” Strategy and “Cabbage” Strategy
Some observers characterize China’s approach for asserting and defending its territorial claims in
the ECS and SCS as a “salami-slicing” strategy that employs a series of incremental actions, none
of which by itself is a casus belli, to gradually change the status quo in China’s favor.32 At least

one Chinese official has used the term “cabbage strategy” to refer to a strategy of consolidating
control over disputed islands by wrapping those islands, like the leaves of a cabbage, in
successive layers of occupation and protection formed by fishing boats, Chinese Coast Guard
ships, and then finally Chinese naval ships.33 Other observers have referred to China’s approach
as a strategy of creeping annexation34 or as a “talk and take” strategy, meaning a strategy in which
China engages in (or draws out) negotiations while taking actions to gain control of contested
areas.35
Use of China Coast Guard Ships and Other Ships
China makes regular use of China Coast Guard ships to assert and defend its maritime territorial
claims, with Chinese Navy ships sometimes available over the horizon as backup forces.36

36 The Department of Defense (DOD) states:
During the 2012 Scarborough Reef and 2013 Senkaku Islands tensions, the China Maritime
Surveillance (CMS) and Fisheries Law Enforcement Command (FLEC) ships were responsible for
directly asserting Chinese sovereignty on a daily basis, while the PLA Navy maintained a more
distant presence from the immediate vicinity of the contested waters. China prefers to use its
civilian maritime agencies around these islands, and uses the PLA Navy in a back-up role or as an
escalatory measure. China’s diplomats also apply pressure on rival claimants. China identifies its
territorial sovereignty as a core interest and emphasizes its willingness to protect against actions
that China perceives challenge Chinese sovereignty. China almost certainly wants to assert its
maritime dominance without triggering too harsh of a regional backlash.
In 2013, China consolidated four of its maritime law enforcement agencies into the China Coast
Guard (CCG). Subordinate to the Ministry of Public Security, the CCG is responsible for a wide
range of missions, including maritime sovereignty enforcement missions, anti-smuggling, maritime
rescue and salvage, protecting fisheries resources, and general law enforcement. Prior to the
consolidation, different agencies were responsible for each of these mission sets, creating
organizational redundancies and complicating interagency coordination.
In the next decade, a new force of civilian maritime ships will afford China the capability to patrol
its territorial claims more robustly in the East China and the South China Seas. China is continuing
with the second half of a modernization and construction program for the CCG. The first half of
this program, from 2004 to 2008, resulted in the addition of almost 20 ocean-going patrol ships.
The second half of this program, from 2011 to 2015, includes at least 30 new ships for the CCG.
Several less capable patrol ships will be decommissioned during this period. In addition, the CCG

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Chinese Coast Guard ships are unarmed or lightly armed, but can be effective in asserting and
defending maritime territorial claims, particularly in terms of confronting or harassing foreign
vessels that are similarly lightly armed or unarmed.37 In addition to being available as backups for
China Coast Guard ships, Chinese navy ships conduct exercises that in some cases appear
intended, at least in part, at reinforcing China’s maritime claims.38 Some observers believe China
also uses civilian fishing ships to assert and defend its maritime claims.39
Preference for Treating Disputes on Bilateral Basis
China prefers to discuss maritime territorial disputes with other parties to the disputes on a
bilateral rather than multilateral basis. Some observers believe China prefers bilateral talks
because China is much larger than any other country in the region, giving China a potential upper
hand in any bilateral meeting. China generally has resisted multilateral approaches to resolving
maritime territorial disputes, stating that such approaches would internationalize the disputes,
although the disputes are by definition international even when addressed on a bilateral basis.
(China’s participation with the ASEAN states in the 2002 DOC and in negotiations with the
ASEAN states on the follow-on binding code of conduct represents a departure from this general
preference.) As noted above, some observers believe China is pursuing a policy of putting off a
negotiated resolution of maritime territorial disputes so as to give itself time to implement the
salami-slicing strategy.40 China has resisted U.S. involvement in the disputes.41

will likely build more than 100 new patrol craft and smaller units, both to increase capability and to
replace old units. Overall, The CCG’s total force level is expected to increase by 25 percent. Some
of these ships will have the capability to embark helicopters, a capability that only a few MLE
[maritime law enforcement] ships currently have. The enlargement and modernization of China’s
MLE forces will improve China’s ability to enforce its maritime sovereignty.

Chinese ends.” (Donald K. Emmerson, “China Challenges Philippines in the South China Sea,” East Asia Forum

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Comparison with U.S. Actions Toward Caribbean and Gulf of Mexico
Some observers have compared China’s approach toward its near-seas region with the U.S.
approach toward the Caribbean and the Gulf of Mexico in the age of the Monroe Doctrine. One
observer, for example, states:
Beijing is attempting to do in the East and South China Seas in the early twenty-first century
what the United States successfully accomplished in the Greater Caribbean in the nineteenth
and early-twentieth centuries. It has attempted to take effective strategic control of the blue
water extension of its own continental land mass.42
It can be noted, however, that there are significant differences between China’s approach to its
near-seas region and the U.S. approach—both in the 19th and 20th Centuries and today—to the
Caribbean and the Gulf of Mexico. Unlike China in its approach to its near-seas region, the
United States has not asserted any form of sovereignty or historical rights over the broad waters
of the Caribbean or Gulf of Mexico (or other sea areas beyond the 12-mile limit of U.S. territorial
waters), has not published anything akin to the nine-dash line for these waters (or other sea areas
beyond the 12-mile limit), and does not contest the right of foreign naval forces to operate and
engage in various activities in waters beyond the 12-mile limit. One observer states:
Chinese interlocutors are forever trying to use facile comparisons with U.S. history to get
Americans to commit to unilateral intellectual disarmament. If we did it in the Caribbean
then, how can we object when China does it in Southeast Asia now?...
While China’s methods in nearby waters bear some resemblance to fin de siècle America’s,
its goals could hardly be more different. The difference is between closed seas and skies
ruled by a strong coastal state and freedom of the maritime commons....
[The United States] never claimed ownership of the greater Caribbean, however much it
coveted primacy there. There was no American counterpart to the nine-dashed line.
Nor, despite occasional glances toward Cuba and other islands, did Washington regard these
jewels of the Caribbean as rightful U.S. property. Nor did any significant school of foreign-
policy thought regard southern waters as a seaward extension of the North American
landmass. Still less did official policy consider the sea sovereign territory or “blue national
soil,” to borrow the ubiquitous Chinese phrase for the near seas.
Instead, the Monroe Doctrine was a unilateral directive forbidding European empires to
reconquer American republics that had won their independence. The doctrine was popular in
Latin America for decades....
Only in the 1910s did the Monroe Doctrine truly fall into disrepute in Latin America. That’s
when U.S. leaders took to using it abusively, as a pretext for diplomatic and military
interventionism rather than a common defense of the Americas.
Yet U.S. statesmen didn’t cling hardheadedly to even this most cherished of foreign-policy
doctrines. In the 1920s, Washington retracted the Theodore Roosevelt “Corollary” to the
doctrine, which Presidents William Howard Taft and Woodrow Wilson invoked as a license
for intervention in Caribbean nations’ affairs. Presidents Herbert Hoover and Franklin

Roosevelt subsequently ushered in the pan-American defense system that remains in place to
this day.
In effect Hoover and FDR internationalized the Monroe Doctrine, enlisting fellow American
states as co-guarantors of hemispheric security. Can you imagine Beijing walking back its
nine-dashed line in similar fashion? One can hope—but don’t hold your breath.
So let’s not drink the Kool-Aid Beijing is peddling. When it disavows its claim to
“indisputable sovereignty” over the South China Sea, reverses longstanding policy to favor
freedom of the seas and skies, and, most importantly, wins buy-in from Asian neighbors,
then I’ll be glad to welcome comparisons [with what the United States wanted to accomplish
in the Caribbean Sea and the Gulf of Mexico in the age of the Monroe Doctrine].43
Chinese Actions Since Late 2013 That Have Heightened Concerns
Following a confrontation in 2012 between Chinese and Philippine ships at Scarborough Shoal,
China gained de facto control over access to the shoal. Subsequent Chinese actions for asserting
and defending China’s claims in the ECS and SCS that have heightened concerns among
observers, particularly since late 2013, include the following:
• ongoing Chinese pressure against the Philippine presence at Second Thomas
Shoal, a submerged shoal in the Spratly Islands;44
• frequent patrols by Chinese Coast Guard ships—some observers refer to them as
harassment operations—at the Senkaku Islands;
• China’s announcement on November 23, 2013, of an air defense identification
zone (ADIZ) for the ECS that includes airspace over the Senkaku Islands;
• the previously mentioned December 5, 2013, incident in which a Chinese navy
ship put itself in the path of the U.S. Navy cruiser Cowpens, forcing the Cowpens
to change course to avoid a collision;
• the implementation on January 1, 2014, of fishing regulations administered by
China’s Hainan province applicable to waters constituting more than half of the
SCS, and the reported enforcement of those regulations with actions that have
included the apprehension of non-Chinese fishing boats;45
• land-reclamation activities, publicly reported starting in May 2014, at locations in
the SCS occupied by China that observers view as a prelude to the construction
of expanded Chinese facilities and fortifications at those locations;46 and

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

• moving a large oil rig in May 2014 into waters that are near the Paracels and
inside Vietnam’s claimed EEZ, and using dozens of Chinese Coast Guard and
Chinese navy ships to enforce a large keep-away zone around the rig, leading to
numerous confrontations and incidents between Chinese and Vietnamese civilian
and military ships.47
At a February 5, 2014, hearing before the subcommittee on Asia and the Pacific of the House
Foreign Affairs Committee, Assistant Secretary of State Daniel Russel testified that
Deputy Secretary [of State William J.] Burns and I were in Beijing earlier this month to hold
regular consultations with the Chinese government on Asia-Pacific issues, and we held
extensive discussions regarding our concerns. These include continued restrictions on access
to Scarborough Reef; pressure on the long-standing Philippine presence at the Second
Thomas Shoal; putting hydrocarbon blocks up for bid in an area close to another country’s
mainland and far away even from the islands that China is claiming; announcing
administrative and even military districts in contested areas in the South China Sea; an
unprecedented spike in risky activity by China’s maritime agencies near the Senkaku Islands;
the sudden, uncoordinated and unilateral imposition of regulations over contested airspace in
the case of the East China Sea Air Defense Identification Zone; and the recent updating of
fishing regulations covering disputed areas in the South China Sea. These actions have raised
tensions in the region and concerns about China’s objectives in both the South China and the
East China Seas.
There is a growing concern that this pattern of behavior in the South China Sea reflects an
incremental effort by China to assert control over the area contained in the so-called “nine-
dash line,” despite the objections of its neighbors and despite the lack of any explanation or
apparent basis under international law regarding the scope of the claim itself.48

behavior is not beyond reproach, China might have a better case to make if it would adhere to international law. China
has every right to protect a drilling rig inside its territorial waters, but a rig outside of its 12-nautical-mile territorial
waters is entitled to only a 500-meter safety zone.” (Patrick M. Cronin, “US Should Help Vietnam Counter China’s

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

U.S. Position on These Issues
Some Key Elements
The U.S. position on territorial and EEZ disputes in the Western Pacific (including those
involving China) includes the following elements, among others:
• The United States takes no position on competing claims to sovereignty over
disputed land features in the ECS and SCS.
• Claims of territorial waters and EEZs should be consistent with customary
international law of the sea and must therefore, among other things, derive from
land features. Claims in the SCS that are not derived from land features are
fundamentally flawed.
• Territorial disputes should be resolved peacefully, without coercion, intimidation,
threats, or the use of force.
• Parties should avoid taking provocative or unilateral actions that disrupt the
status quo or jeopardize peace and security; the Senkaku Islands are under the
administration of Japan and unilateral attempts to change the status quo raise
tensions and do nothing under international law to strengthen territorial claims.
• The United States has a national interest in the preservation of freedom of seas as
recognized in customary international law of the sea. The United States opposes
claims that impinge on the rights, freedoms, and lawful uses of the sea that
belong to all nations.
• The United States, like most other countries, believes that coastal states under
UNCLOS have the right to regulate economic activities in their EEZs, but do not
have the right to regulate foreign military activities in their EEZs.
February 5, 2014, State Department Testimony
At a February 5, 2014, hearing before the subcommittee on Asia and the Pacific of the House
Foreign Affairs Committee, Assistant Secretary of State Daniel Russel testified that
Since the end of the Second World War, a maritime regime based on international law that
promotes freedom of navigation and lawful uses of the sea has facilitated Asia’s impressive
economic growth. The United States, through our our [sic] alliances, our security
partnerships and our overall military presence and posture, has been instrumental in
sustaining that maritime regime and providing the security that has enabled the countries in
the region to prosper. As a maritime nation with global trading networks, the United States
has a national interest in freedom of the seas and in unimpeded lawful commerce. From
President Thomas Jefferson’s actions against the Barbary pirates to President Reagan’s
decision that the United States will abide by the Law of the Sea Convention’s provisions on
navigation and other traditional uses of the ocean, American foreign policy has long
defended the freedom of the seas. And as we consistently state, we have a national interest in
the maintenance of peace and stability; respect for international law; unimpeded lawful
commerce; and freedom of navigation and overflight in the East China and South China
Seas....
Congressional Research Service

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Mr. Chairman, we have a deep and long-standing stake in the maintenance of prosperity and
stability in the Asia-Pacific and an equally deep and abiding long-term interest in the
continuance of freedom of the seas based on the rule of law—one that guarantees, among
other things, freedom of navigation and overflight and other internationally lawful uses of
the sea related to those freedoms. International law makes clear the legal basis on which
states can legitimately assert their rights in the maritime domain or exploit marine resources.
By promoting order in the seas, international law is instrumental in safeguarding the rights
and freedoms of all countries regardless of size or military strength.
I think it is imperative that we be clear about what we mean when the United States says that
we take no position on competing claims to sovereignty over disputed land features in the
East China and South China Seas. First of all, we do take a strong position with regard to
behavior in connection with any claims: we firmly oppose the use of intimidation, coercion
or force to assert a territorial claim. Second, we do take a strong position that maritime
claims must accord with customary international law. This means that all maritime claims
must be derived from land features and otherwise comport with the international law of the
sea. So while we are not siding with one claimant against another, we certainly believe that
claims in the South China Sea that are not derived from land features are fundamentally
flawed. In support of these principles and in keeping with the longstanding U.S. Freedom of
Navigation Program, the United States continues to oppose claims that impinge on the rights,
freedoms, and lawful uses of the sea that belong to all nations.
As I just noted, we care deeply about the way countries behave in asserting their claims or
managing their disputes. We seek to ensure that territorial and maritime disputes are dealt
with peacefully, diplomatically and in accordance with international law. Of course this
means making sure that shots aren’t fired; but more broadly it means ensuring that these
disputes are managed without intimidation, coercion, or force. We have repeatedly made
clear that freedom of navigation is reflected in international law, not something to be granted
by big states to others....
China’s lack of clarity with regard to its South China Sea claims has created uncertainty,
insecurity and instability in the region. It limits the prospect for achieving a mutually
agreeable resolution or equitable joint development arrangements among the claimants. I
want to reinforce the point that under international law, maritime claims in the South China
Sea must be derived from land features. Any use of the “nine dash line” by China to claim
maritime rights not based on claimed land features would be inconsistent with international
law. The international community would welcome China to clarify or adjust its nine-dash
line claim to bring it in accordance with the international law of the sea.
We support serious and sustained diplomacy between the claimants to address overlapping
claims in a peaceful, non-coercive way. This can and should include bilateral as well as
multilateral diplomatic dialogue among the claimants. But at the same time we fully support
the right of claimants to exercise rights they may have to avail themselves of peaceful
dispute settlement mechanisms. The Philippines chose to exercise such a right last year with
the filing of an arbitration case under the Law of the Sea Convention.49

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

May 31, 2014, Secretary of Defense Speech
On May 31, 2014, in a speech at an international conference in Singapore called the Shangri-La
Dialogue, Secretary of Defense Chuck Hagel stated in part:
One of the most critical tests facing the region is whether nations will choose to resolve
disputes through diplomacy and well-established international rules and norms…or through
intimidation and coercion. Nowhere is this more evident than in the South China Sea, the
beating heart of the Asia-Pacific and a crossroads for the global economy.
China has called the South China Sea “a sea of peace, friendship, and cooperation.” And
that’s what it should be.
But in recent months, China has undertaken destabilizing, unilateral actions asserting its
claims in the South China Sea. It has restricted access to Scarborough Reef, put pressure on
the long-standing Philippine presence at the Second Thomas Shoal, begun land reclamation
activities at multiple locations, and moved an oil rig into disputed waters near the Paracel
Islands.
The United States has been clear and consistent. We take no position on competing territorial
claims. But we firmly oppose any nation’s use of intimidation, coercion, or the threat of
force to assert those claims.
We also oppose any effort—by any nation—to restrict overflight or freedom of navigation—
whether from military or civilian vessels, from countries big or small. The United States will
not look the other way when fundamental principles of the international order are being
challenged.
We will uphold those principles. We made clear last November that the U.S. military would
not abide by China’s unilateral declaration of an Air Defense Identification Zone in the East
China Sea, including over the Japanese-administered Senkaku Islands. And as President
Obama clearly stated in Japan last month, the Senkaku Islands are under the mutual defense
treaty with Japan.
All nations of the region, including China, have a choice: to unite, and recommit to a stable
regional order, or to walk away from that commitment and risk the peace and security that
have benefitted millions of people throughout the Asia-Pacific, and billions around the
world.
The United States will support efforts by any nation to lower tensions and peacefully resolve
disputes in accordance with international law.
We all know that cooperation is possible. Last month, 21 nations signed the Code for
Unplanned Encounters at Sea—an important naval safety protocol. ASEAN and China are
negotiating a Code of Conduct for the South China Sea—and the United States encourages
its early conclusion. Nations of the region have also agreed to joint energy exploration; this
month, the Philippines and Indonesia resolved a longstanding maritime boundary dispute;
and this week, Taiwan and the Philippines agreed to sign a new fisheries agreement.
China, too, has agreed to third-party dispute resolution in the World Trade Organization;
peacefully resolved a maritime boundary dispute with Vietnam in 2000; and signed
ASEAN’s Treaty of Amity and Cooperation.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

For all our nations, the choices are clear, and the stakes are high. These stakes are not just
about the sovereignty of rocky shoals and island reefs, or even the natural resources that
surround them and lie beneath them. They are about sustaining the Asia-Pacific’s rules-based
order, which has enabled the people of this region to strengthen their security, allowing for
progress and prosperity. That is the order the United States—working with our partners and
allies—that is the order that has helped underwrite since the end of World War II. And it is
the order we will continue to support—around the world, and here in the Asia-Pacific.50
June 25, 2014, State Department Testimony
At a June 25, 2014, hearing before the Senate Foreign Relations Committee, Assistant Secretary
of State Daniel Russel testified that
We believe all countries, and particularly emerging powers like China, should recognize the
self-benefit of upholding basic rules and norms on which the international system is built;
these are rules and norms which China has participated in formulating and shaping, and they
are rules and norms that it continues to benefit from. In this context, we are encouraging
China to exercise restraint in dealing with its neighbors and show respect for universal values
and international law both at home and abroad....
In the Asia-Pacific region, Beijing’s neighbors are understandably alarmed by China’s
increasingly coercive efforts to assert and enforce its claims in the South China and East
China Seas. A pattern of unilateral Chinese actions in sensitive and disputed areas is raising
tensions and damaging China’s international standing. Moreover, some of China’s actions
are directed at U.S. treaty allies. The United States has important interests at stake in these
seas: freedom of navigation and overflight, unimpeded lawful commerce, respect for
international law, and the peaceful management of disputes. We apply the same principles to
the behavior of all claimants involved, not only to China. China—as a strong and rising
power—should hold itself to a high standard of behavior; to willfully disregard diplomatic
and other peaceful ways of dealing with disagreements and disputes in favor of economic or
physical coercion is destabilizing and dangerous.
The United States does not take sides on the sovereignty questions underlying the territorial
disputes in the South and East China Seas, but we have an interest in the behavior of states in
their management or resolution of these disputes. We want countries, including China, to
manage or settle claims through peaceful, diplomatic means. For example, the Philippines
and Indonesia have just done so in connection with their EEZ boundary. Disputes can also be
addressed through third-party dispute resolution processes. Where parties’ rights under
treaties may be affected, some treaties provide for third-party dispute settlement, as is the
case of the Law of the Sea Convention, an avenue pursued by the Philippines in an
arbitration with China currently being considered by an Arbitral Tribunal constituted under
that treaty. The United States and the international community oppose the use or the threat of
force to try to advance a claim, and view such actions as having no effect in strengthening
the legitimacy of China’s claims. These issues should be decided on the basis of the merits of
China’s and other claimants’ legal claims and adherence to international law and norms, not
the strength of their militaries and law enforcement ships or the size of their economies.51

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Operational Rights in EEZs
Regarding a coastal state’s rights within its EEZ, Scot Marciel, then-Deputy Assistant Secretary,
Bureau of East Asian and Pacific Affairs, stated the following as part of his prepared statement
for a July 15, 2009, hearing before the East Asian and Pacific Affairs subcommittee of the Senate
Foreign Relations Committee:
I would now like to discuss recent incidents involving China and the activities of U.S.
vessels in international waters within that country’s Exclusive Economic Zone (EEZ). In
March 2009, the survey ship USNS Impeccable was conducting routine operations,
consistent with international law, in international waters in the South China Sea. Actions
taken by Chinese fishing vessels to harass the Impeccable put ships of both sides at risk,
interfered with freedom of navigation, and were inconsistent with the obligation for ships at
sea to show due regard for the safety of other ships. We immediately protested those actions
to the Chinese government, and urged that our differences be resolved through established
mechanisms for dialogue—not through ship-to-ship confrontations that put sailors and
vessels at risk.
Our concern over that incident centered on China’s conception of its legal authority over
other countries’ vessels operating in its Exclusive Economic Zone (EEZ) and the unsafe way
China sought to assert what it considers its maritime rights.
China’s view of its rights on this specific point is not supported by international law. We
have made that point clearly in discussions with the Chinese and underscored that U.S.
vessels will continue to operate lawfully in international waters as they have done in the
past.52
As part of his prepared statement for the same hearing, Robert Scher, then-Deputy Assistant
Secretary of Defense, Asian and Pacific Security Affairs, Office of the Secretary of Defense,
stated that
we reject any nation’s attempt to place limits on the exercise of high seas freedoms within an
exclusive economic zones [sic] (EEZ). Customary international law, as reflected in articles
58 and 87 of the 1982 United Nations Convention on the Law of the Sea, guarantees to all
nations the right to exercise within the EEZ, high seas freedoms of navigation and overflight,
as well as the traditional uses of the ocean related to those freedoms. It has been the position
of the United States since 1982 when the Convention was established, that the navigational
rights and freedoms applicable within the EEZ are qualitatively and quantitatively the same
as those rights and freedoms applicable on the high seas. We note that almost 40% of the
world’s oceans lie within the 200 nautical miles EEZs, and it is essential to the global
economy and international peace and security that navigational rights and freedoms within
the EEZ be vigorously asserted and preserved.
As previously noted, our military activity in this region is routine and in accordance with
customary international law as reflected in the 1982 Law of the Sea Convention.53

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

U.S. Freedom of Navigation (FON) Program
U.S. Navy ships carry out assertions of operational rights as part of the U.S. Freedom of
Navigation (FON) program for challenging maritime claims that the United States believes to be
inconsistent with international law.54 The Department of Defense’s (DOD’s) record of “excessive
maritime claims that were challenged by DoD operational assertions and activities during the
period of October 1, 2012, to September 30, 2013, in order to preserve the rights, freedoms, and
uses of the sea and airspace guaranteed to all nations in international law” includes a listing for
multiple challenges that were conducted to challenge Chinese claims relating to “excessive
straight baselines; security jurisdiction in contiguous zone; jurisdiction over airspace above the
exclusive economic zone (EEZ); domestic law criminalizing survey activity by foreign entities in
EEZ; [and] prior permission required for innocent passage of foreign military ships through
territorial sea.”55
Potential Implications for United States
China’s actions for asserting and defending its maritime territorial and EEZ claims in the ECS
and SCS, particularly since late 2013, have heightened concerns among observers that ongoing
disputes over these waters and some of the islands within them could lead to a crisis or conflict
between China and a neighboring country such as Japan, the Philippines, or Vietnam, and that the
United States could be drawn into such a crisis or conflict as a result of obligations the United
States has under bilateral security treaties with Japan and the Philippines.

54 The State Department states that
U.S. Naval forces engage in Freedom of Navigation operations to assert the principles of

international community has accepted these unlawful claims. ISO coordinates DOS clearance for
FON operations.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

More broadly, China’s actions for asserting and defending its maritime territorial and EEZ claims
have led to increasing concerns among some observers that China may be seeking to dominate or
gain control of its near-seas region, meaning the ECS, the SCS, and the Yellow Sea.56 Chinese
domination over or control of this region could have major implications for the United States,
including implications for U.S.-China relations, for interpreting China’s rise as a major world
power, for the security structure of the Asia-Pacific region, for the long-standing U.S. strategic
goal of preventing the emergence of a regional hegemon in one part of Eurasia or another, and for
two key elements of the U.S.-led international order that has operated since World War II—the
non-use of force or coercion as a means of settling disputes between countries, and freedom of
the seas.

56 For example, one observer states that “The long and ongoing record of unilateral Chinese assertions or aggressions in
the South and East China Sea no longer leaves room for doubt as to Beijing’s intention. China wants and is trying to
achieve dominance over the waters behind what it calls the ‘first island chain’ and land features that fringe the U-
shaped line. The question is not ‘what does China intend?’ The answer—dominance of some kind and degree—is
known. The question is ‘what, if anything, is anyone else prepared to do?’” (Donald K. Emmerson, “China Challenges
Philippines in the South China Sea,” East Asia Forum (www.eastasiaforum.org), March 18, 2014.)
Another observer states that “For more than a decade, the Chinese government has been pursuing a deliberate, yet
indirect strategy to establish de facto control over the waters and airspace adjacent to its mainland.” (Daniel Goure,
“New Chinese Air Defense Zone Is latest Move In Beijing’s Strategy To Dominate East Asia,” Lexington Institute
Early Warnnig Blog (www.lexingtoninstitute.org), November 25, 2013.) A December 4, 2013, press report states:
“China’s escalation in its challenge to Japan’s administration of islands near Taiwan reflects an effort to gain greater
command of the air and seas in the western Pacific as it builds itself into a maritime power.” (Henry Sanderson and
Shai Oster, “China Air Zone Seen Step to Expanding Access to West Pacific,” Bloomberg News
(www.bloomberg.com), December 4, 2013.
Another observer states that “Beijing seeks to wield this growing might to pursue outstanding territorial and maritime
claims and to carve out in the Yellow, East and South China Seas and airspace above them a ‘zone of exceptionalism’
within which existing global security, legal, and resource management norms are subordinated to its parochial national
interests. This can only weaken the global system on which all nations’ security and prosperity depends, and will
continue to destabilize a vital but vulnerable region that remains haunted by history.” (Andrew S. Erickson,
“Deterrence by Denial: How to Prevent China From Using Force,” National Interest (http://nationalinterest.org),
December 16, 2013.)
Another observer states that “The Chinese have long felt vulnerable from the sea and their current maritime strategy
seeks to reduce that vulnerability by extending a ring of maritime control around China’s periphery.... First and
foremost, it is the failure of previous Chinese leaders to close the maritime gap in China’s arc of security and the
invasions that resulted that motivates China’s current leaders to extend strategic power over the near seas. Extending
Chinese control over the near seas therefore is seen as enhancing security for the Chinese state and healing a sort of
psychological wound in the collective Chinese mind.
” (Statement of Peter A. Dutton, Professor and Director, China
Maritime Studies Institute, U.S. Naval War College, Testimony before the House Foreign Affairs Committee Hearing
on China’s Maritime Disputes in the East and South China Seas, January 14, 2014, pp. 2, 3. Italics as in original. [The
hearing was actually a joint hearing before Seapower and Projection Forces subcommittee of the House Armed
Services Committee and the Asia and the Pacific subcommittee of the House Foreign Affairs Committee.])
Another observer states that “The Yalong Bay naval base on [China’s] Hainan [island] is one part of the strategy that
China is starting to put in place to exert control over the Near Seas, pushing the US Navy ever farther out into the
Western Pacific.... By weakening the US naval presence in the western Pacific, China hopes gradually to undermine
America’s alliances with other Asian countries, notably South Korea, the Philippines and maybe even Japan. If US
influence declines, China would be in a position to assume quietly a leadership position in Asia, giving it much greater
sway over the rules and practices in the global economy.... China’s stepped-up claim over the [Senkaku] islands is one
art of its push for greater control of the surrounding seas but it is also a central part of the growing contest for influence
with the US.” (Geoff Dyer, “US v China: Is This The New Cold War?” Financial Times (www.ft.com), February 20,
2014.
Another observer states that China’s ECS ADIZ “can be regarded as just one element in a larger strategy of trying to
assert sovereignty in the East China Sea and vast parts of the South China Sea, as reflected in Beijing’s ‘nine-dashed
line.’” (Benjamin Schreer, “China’s Rise: The Strategic Climate Is Getting Colder,” The Strategist (The Australian
Strategic Policy Institute Blog)

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Risk of United States Being Drawn Into a Crisis or Conflict
Many observers are concerned that ongoing maritime territorial disputes in the ECS and SCS
could lead to a crisis or conflict between China and a neighboring country such as Japan, the
Philippines, and that the United States could be drawn into such a crisis or conflict as a result of
obligations the United States has under bilateral security treaties with Japan and the Philippines.
U.S. officials, concerned about the risk that a misunderstanding or miscalculation might cause a
dispute over island territories to escalate into a conflict, have urged parties involved in the
disputes to exercise restraint and avoid taking provocative actions.
U.S.-Japan Treaty on Mutual Cooperation and Security
The 1960 U.S.-Japan treaty on mutual cooperation and security57 states in Article V that
Each Party recognizes that an armed attack against either Party in the territories under the
administration of Japan would be dangerous to its own peace and safety and declares that it
would act to meet the common danger in accordance with its constitutional provisions and
processes.
The United States has reaffirmed on a number of occasions over the years that since the Senkaku
Islands are under the administration of Japan, they are included in the territories referred to in
Article V of the treaty, and that the United States “will honor all of our treaty commitments to our
treaty partners.”58 (At the same time, the United States, noting the difference between
administration and sovereignty, has noted that such affirmations do not prejudice the U.S.
approach of taking no position regarding the outcome of the dispute between China, Taiwan, and
Japan regarding who has sovereignty over the islands.) Some observers, while acknowledging the
U.S. affirmations, have raised questions regarding the potential scope of actions that the United
States might take under Article V.59

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

U.S.-Philippines Mutual Defense Treaty60
The 1951 U.S.-Philippines mutual defense treaty61 states in Article IV that
Each Party recognizes that an armed attack in the Pacific Area on either of the Parties would
be dangerous to its own peace and safety and declares that it would act to meet the common
dangers in accordance with its constitutional processes.
Article V states that
For the purpose of Article IV, an armed attack on either of the Parties is deemed to include
an armed attack on the metropolitan territory of either of the Parties, or on the island
territories under its jurisdiction in the Pacific or on its armed forces, public vessels or aircraft
in the Pacific.
The United States has reaffirmed on a number of occasions over the years its obligations under
the U.S.-Philippines mutual defense treaty.62 On May 9, 2012, Filipino Foreign Affairs Secretary
Albert F. del Rosario issued a statement providing the Philippine perspective regarding the
treaty’s application to territorial disputes in the SCS.63 U.S. officials have made their own
statements regarding the treaty’s application to territorial disputes in the SCS.64

Developments regarding China’s maritime territorial and EEZ disputes in the ECS and SCS could

Interpreting China’s Rise as a Major World Power
As China emerges as a major world power, observers are assessing what kind of international

such as China’s approach to settling disputes between states (including whether China views

force and coercion as acceptable means for settling such disputes, and consequently whether
China believes that “might makes right”), China’s views toward the meaning and application of
international law, and whether China views itself more as a stakeholder and defender of the
current international order, or alternatively, more as a revisionist power that will seek to change
elements of that order that it does not like.
Security Structure of Asia-Pacific Region
Chinese domination over or control of its near-seas region could have significant implications for
the security structure of the Asia-Pacific region. In particular, Chinese domination over or control
of its near-seas area could greatly complicate the ability of the United States to fulfill its
obligations to Taiwan under the Taiwan Relations Act (H.R. 2479/P.L. 96-8 of April 10, 1979).66
It could also complicate the ability of the United States to fulfill its obligations under security and
defense treaties with other countries in the region, particularly Japan, South Korea, the
Philippines, and Thailand.67 More generally, it could complicate the ability of the United States to
operate U.S. forces in the Western Pacific for various purposes, including maintaining regional
stability, conducting engagement and partnership-building operations, responding to crises, and
executing war plans. Developments such as these could in turn encourage countries in the region
to reexamine their own defense programs and foreign policies, potentially leading to a further
change in the region’s security structure.
U.S. Strategic Goal of Preventing Emergence of Regional Hegemon in Eurasia
Observers who are concerned that China may be seeking to dominate or gain control of its near-
seas region in some cases go further, expressing concern that this may be part of a larger Chinese
effort to become the hegemonic power in its region.68 From a standpoint of U.S. strategic policy,

66 For more on the Taiwan Relations Act, see CRS Report R41952, U.S.-Taiwan Relationship: Overview of Policy
Issues
, by Shirley A. Kan and Wayne M. Morrison.
67 The United States has bilateral treaties with Japan, South Korea, and the Philippines. The United States and Thailand
are parties to a Southeast Asia collective defense treaty that also includes the United Kingdom France, Australia, and
New Zealand. The United States also has a separate treaty with Australia and New Zealand. For a summary of U.S.
collective defense treaties, see the list posted at http://www.state.gov/s/l/treaty/collectivedefense/.
68 One observer, for example, states that “Our approach has been, and must continue to be, that no one country
dominates Asia. That objective, our role, and our strategic interests are being challenged by China. It is apparent in the
growth in capability and capacity of the PLA (especially naval and air forces) and in the way China is defining (or
redefining) maritime and air boundaries. Strategic space is being reshaped spatially by military capabilities and
behaviorally by dubious maritime and airspace claims. The latter is particularly critical and points to a fundamental
difference in our strategic competition with China.” (Gary Roughead, “China, Time and Rebalancing,” Hoover
Institution (www.hoover.org), undated (but with copyright of 2014), accessed March 25, 2014, at
http://www.hoover.org/taskforces/military-history/strategika/11/roughead.) Another observer states that “China has
historically been the Middle Kingdom, and it is now reasserting its perceived right to hegemonic status in East Asia.”
(Jim Talent, “The Equilibrium of East Asia,” National Review Online (http://www.nationalreview.com), December 5,
2013.) Another observer states that “it is not clear yet if indeed China seeks regional hegemony. But there is a growing
consensus among American and Japanese analysts that this is indeed the case. By Chinese hegemony in Asia we
broadly mean something akin to the United States’ position in Latin America. We do not mean actual conquest. Almost
no one believes China intends to annex even its weakest neighbors like Cambodia or North Korea. Rather, analysts
expect a zone of super-ordinate influence over neighbors.” (Robert E. Kelly, “What Would Chinese Hegemony Look
Like?” The Diplomat (http://thediplomat.com), February 10, 2014.)

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

such an effort would be highly significant, because it has been a long-standing U.S. strategic goal
to prevent the emergence of a regional hegemon in one part of Eurasia or another.69
Non-use of Force or Coercion as a Means of Settling Disputes
Between Countries

A key element of the U.S.-led international order that has operated since World War II is that
force or coercion should not be used as a means of settling disputes between countries, and
certainly not as a routine or first-resort method. Some observers are concerned that some of
China’s actions in asserting and defending its territorial claims in the ECS and SCS challenge this
principal and help reestablish the very different principal of “might makes right” as a routine or
defining characteristic of international relations.70

69 Most of the world’s people, resources, and economic activity are located not in the Western Hemisphere, but in the
other hemisphere, particularly Eurasia. In response to this basic feature of world geography, U.S. policy makers for the
last several decades have chosen to pursue, as a key element of U.S. national strategy, a goal of preventing the
emergence of a regional hegemon in one part of Eurasia or another, on the grounds that such a hegemon could
challenge core U.S. interests by, for example, denying the United States access to important resources and economic
activity in part of Eurasia or establishing alliances with countries in the Western Hemisphere. Although U.S. policy
makers do not often state this key national strategic goal explicitly in public, U.S. military operations in recent
decades—both wartime operations and day-to-day operations—have been carried out in no small part in support of this
key goal. One observer, for example, states that
if a distant great power were to dominate Asia or Europe the way America dominates the Western
Hemisphere, it would then be free to roam around the globe and form alliances with countries in the
Wesern Hemisphere that have an adversarial relationship with the United States. In that
circumstance, the stopping power of the Atlantic and Pacific oceans would be far less effective.
Thus, American policy makers have a deep-seated interest in preventing another great power from
achieving regional hegemony in Asia or Europe.
The Persian Gulf is strategically important because it produces roughly 30 percent of the world’s
oil, and it holds about 55 percent of the world’s cruide-oil reserves. If the flow of oil from that
region were stopped or even severely curtailed for a substantial period of time, it would have a
devastating effect on the world economy. Therefore, the United States has good reason to ensure
that oil flows freely out of the Gulf, which in practice means preventing any single country from
controlling all of that critical resource. Most oil-producing stattes will keep pumping and seeling
their oil as long as they are free to do so, because they depend on the revenues. It is in America’s
interest to keep them that way, which means there can be no regional hegemon in the Gulf, as well
as Asia and Europe....
[The United States] should make sure it remains the most powerful country on the planet, which
means making sure a rising China does not dominate Asia the way the United States dominates the
Western Hemisphere.

70 A “senior State Department official,” in a background briefing, stated that “there is violent or strong agreement
between the U.S. and ASEAN on the principles at stake, principles of freedom of navigation, principles of peaceful

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Freedom of the Seas
Another key element of the U.S.-led international order that has operated since World War II is
the treatment of the world’s seas under international law as international waters (i.e., as a global
commons), and freedom of operations in international waters. The principal is often referred in
shorthand as freedom of the seas. It is also sometimes referred to as freedom of navigation,
although this term can be defined—particularly by parties who might not support freedom of the
seas—in a narrow fashion, to include merely the freedom to navigate (i.e., pass through) sea
areas, as opposed to the freedom for conducting various activities at sea. A more complete way to
refer to the principal, as stated in DOD’s annual FON report, is “the rights, freedoms, and uses of
the sea and airspace guaranteed to all nations in international law.”71 The principal that most of
the world’s seas are to be treated under international law as international waters dates back
hundreds of years.72
Some observers are concerned that China’s maritime territorial claims, particularly as shown in
the map of the nine-dash line, appear to challenge to the principal that the world’s seas are to be
treated under international law as international waters. If such a challenge were to gain
acceptance in the SCS region, it would have broad implications for the United States and other
countries not only in the SCS, but around the world, because international law is universal in
application, and a challenge to a principal of international law in one part of the world, if
accepted, can serve as a precedent for challenging it in other parts of the world. Overturning the
principal of freedom of the seas, so that significant portions of the seas could be appropriated as

(...continued)
this declaration reinforces the perception that China perfers coercion over rule of law mechanisms
to address territorial, sovereignty or jurisdictional issues in the Asia-Pacific. It also follows a
disturbing trend of increasingly hostile Chinese maritime activities, including repeated incursions
by Chinese vessels into the waters and airspace of Japan, the Philippines, Vietnam and other in the
East and South China Seas. These actions threaten freedom of air and maritime navigation, which
are vital national interests of the United States.”
Another observer states:
Allowing Beijing to use force, or even the threat of force, to alter the regional status quo would
have a number of pernicious effects. It would undermine the functioning of the most vibrant portion
of the global commons—sea and air mediums that all nations rely on for trade and prosperity, but
that none own. It would undermine important international norms and encourage the application of
force to more of the world’s many persistent disputes. Finally, it would threaten to destabilize a
region haunted by history that has prospered during nearly seven decades of U.S. forces helping to
preserve peace. No other nation has the capability and lack of territorial claims necessary to play
this still-vital role.

72 The idea that most of the world’s seas should be treated as international waters rather than as a space that could be
appropriated as national territory dates back to Hugo Grotius (1583-1645), a founder of international law, whose 1609
book Mare Liberum (“The Free Sea”) helped to establish the primacy of the idea over the competing idea, put forth by
the legal jurist and scholar John Seldon (1584-1654) in his book 1635 book Mare Clausum (“Closed Sea”), that the sea
could be appropriated as national territory, like the land.

national territory, would overthrow hundreds of years of international legal tradition relating to
the legal status of the world’s oceans.73
More specifically, if China’s position on whether coastal states have a right under UNCLOS to
regulate the activities of foreign military forces in their EEZs were to gain greater international
acceptance under international law, it could substantially affect U.S. naval operations not only in
the SCS and ECS (see Figure 5 for EEZs in the SCS and ECS), but around the world, which in
turn could substantially affect the ability of the United States to use its military forces to defend
various U.S. interests overseas. As shown in Figure 6, significant portions of the world’s oceans
are claimable as EEZs, including high-priority U.S. Navy operating areas in the Western Pacific,
the Persian Gulf, and the Mediterranean Sea.74 The legal right of U.S. naval forces to operate
freely in EEZ waters is important to their ability to perform many of their missions around the
world, because many of those missions are aimed at influencing events ashore, and having to
conduct operations from more than 200 miles offshore would reduce the inland reach and
responsiveness of ship-based sensors, aircraft, and missiles, and make it more difficult to
transport Marines and their equipment from ship to shore. Restrictions on the ability of U.S. naval
forces to operate in EEZ waters could potentially require a change in U.S. military strategy or
U.S. foreign policy goals.75

73 One observer states:
A very old debate has been renewed in recent years: is the sea a commons open to the free use of
all seafaring states, or is it territory subject to the sovereignty of coastal states? Is it to be freedom
of the seas, as Dutch jurist Hugo Grotius insisted? Or is it to be closed seas where strong coastal
states make the rules, as Grotius’ English archnemesis John Selden proposed?
Customary and treaty law of the sea sides with Grotius, whereas China has in effect become a
partisan of Selden. Just as England claimed dominion over the approaches to the British Isles,
China wants to make the rules governing the China seas. Whose view prevails will determine not
just who controls waters, islands, and atolls, but also the nature of the system of maritime trade and
commerce. What happens in Asia could set a precedent that ripples out across the globe. The
outcome of this debate is a big deal.

the world’s oceans. (See the table called “Comparative Sizes of the Various Maritime Zones” at the end of “Maritime

Some observers, in commenting on China’s resistance to U.S. military survey and surveillance
operations in China’s EEZ, have argued that the United States would similarly dislike it if China
or some other country were to conduct military survey or surveillance operations within the U.S.
EEZ. Skeptics of this view might argue that U.S. policy accepts the right of other countries to
operate their military forces freely in waters outside the 12-mile U.S. territorial waters limit, and
that the United States during the Cold War acted in accordance with this position by not
interfering with either Soviet ships (including intelligence-gathering vessels known as AGIs)76
that operated close to the United States or with Soviet bombers and surveillance aircraft that
periodically flew close to U.S. airspace. The U.S. Navy states that

76 AGI was a U.S. Navy classification for the Soviet vessels in question in which the A meant auxiliary ship, the G
meant miscellaneous purpose, and the I meant that the miscellaneous purpose was intelligence gathering. One observer
states:
During the Cold War it was hard for an American task force of any consequence to leave port
without a Soviet “AGI” in trail. These souped-up fishing trawlers would shadow U.S. task forces,
joining up just outside U.S. territorial waters. So ubiquitous were they that naval officers joked
about assigning the AGI a station in the formation, letting it follow along—as it would anyway—
without obstructing fleet operations.
AGIs were configured not just to cast nets, but to track ship movements, gather electronic
intelligence, and observe the tactics, techniques, and procedures by which American fleets transact
business in great waters.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

When the commonly recognized outer limit of the territorial sea under international law was
three nautical miles, the United States recognized the right of other states, including the
Soviet Union, to exercise high seas freedoms, including surveillance and other military
operations, beyond that limit. The 1982 Law of the Sea Convention moved the outer limit of
the territorial sea to twelve nautical miles. In 1983, President Reagan declared that the
United States would accept the balance of the interests relating to the traditional uses of the
oceans reflected in the 1982 Convention and would act in accordance with those provisions
in exercising its navigational and overflight rights as long as other states did likewise. He
further proclaimed that all nations will continue to enjoy the high seas rights and freedoms
that are not resource related, including the freedoms of navigation and overflight, in the
Exclusive Economic Zone he established for the United States consistent with the 1982
Convention.77
DOD states that
the PLA Navy has begun to conduct military activities within the Exclusive Economic Zones
(EEZs) of other nations, without the permission of those coastal states. Of note, the United
States has observed over the past year several instances of Chinese naval activities in the
EEZ around Guam and Hawaii. One of those instances was during the execution of the
annual Rim of the Pacific (RIMPAC) exercise in July/August 2012. While the United States
considers the PLA Navy activities in its EEZ to be lawful, the activity undercuts China’s
decades-old position that similar foreign military activities in China’s EEZ are unlawful.78
Issues for Congress
Maritime territorial and EEZ disputes in the SCS and ECS involving China raise several potential
policy and oversight issues for Congress, including those discussed below.
U.S. Strategy for Countering “Salami-Slicing” Strategy
Particularly in light of the potential implications for the United States if China were to achieve
domination over or control of its near-seas areas (see previous section), one potential oversight
issue for Congress concerns the U.S. strategy for countering China’s “salami-slicing” strategy.
Potential oversight questions for Congress include the following:

77 Navy Office of Legislative Affairs email to CRS dated September 4, 2012. Similarly, some observers have argued
that China’s position regarding the SCS and ECS is similar to the U.S. Monroe Doctrine for Latin America in the 19th
and early-20th centuries. In response to this argument, one observer states that
China’s policy in the near seas today bears scant resemblance to U.S. policy in the Caribbean and
Gulf in the age of the Monroe Doctrine. For one thing, Washington never asserted title to the
Caribbean the way Beijing claims the South China Sea. For another, America never sought to
restrict naval activities in its near seas, whereas China opposes such things as routine aircraft carrier
operations in the Yellow Sea.... In effect, China has vaulted past the most bellicose, most
meddlesome interpretations of the Monroe Doctrine and Roosevelt Corollary.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

• Does the United States have a strategy for countering China’s “salami-slicing”
strategy?
• If the United States does have such a strategy, what are its key elements, and has
it been effective? Should the strategy be changed, and if so, how?
• If the United States does not have such a strategy, does the Administration intend
to create one, and if so, by when?
Comments by Some Observers on Whether the United States Has a Strategy
One observer states:
Salami-slicing places rivals, especially conflicted rivals, in an uncomfortable position. It is
the rivals of salami-slicers who are obligated to eventually draw red lines and engage in
brinkmanship over actions others will view, in isolation, as trivial and far from constituting
casus belli. China’s leaders are apparently counting on such hesitancy, a calculation that thus
far is working out for them....
... there is no visible response by the U.S. government to China’s salami-slicing. U.S.
officials... have expressed regret over China’s ADIZ declaration, and stated their intention to
carry on with usual U.S. military operations inside that zone and elsewhere in the region. Yet
China has suffered no penalty for its series of actions. Regarding the disputed claims in the
two seas, the official policy from Washington is that China’s neighbors are on their own—
the U.S. will not take sides in these territorial disputes. The United States also objects to the
use of coercion in resolving the disputes. But each individual act of China’s salami-slicing is
carefully calibrated to fall below a threshold most outside observers would view as overt
coercion.
With no resistance to its actions, Chinese salami-slicing will certainly continue....
When the salami-slices sum up to a substantial security problem for Japan, India, and the
ASEAN countries, someone is likely to draw a red line somewhere. The issue for U.S.
officials is whether they will be the ones to do that drawing, and thus retain the initiative, or
whether someone else, having lost confidence in Washington, will do it instead. When that
happens, the U.S. will find itself reacting to events, rather than shaping a favorable outcome
in advance.79
Another observer states that
the problem with [the U.S. military’s Air-Sea Battle, or ASB, concept] (and its main
competitors) is that they are only designed for high-level conflict, and thus can only be
implemented if the U.S. and China move from a state of tense peace to a state of total war. In
other words, unless China takes a brazenly provocative action such as invading Taiwan or
parts of Japan, ASB is more or less useless. No U.S. president is going to order the U.S.
military to take the extremely provocative actions that ASB would require because of, say,
recent actions by China setting up an oil rig in waters that it disputes with Vietnam.

(http://warontherocks.com), February 6, 2014.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

This is problematic. Thus far, China’s military strategy for the South and East China Seas
has been one of using salami-slicing tactics to gradually change facts on the ground. In the
face of these salami-slicing tactics, ASB is of complete irrelevance.
Moreover, China’s salami-slicing tactics appear to be working. It has already gained control
over Scarborough Shoal from the Philippines, and appears poised to do the same in the
Second Thomas Shoal. Its claims to waters around the Paracel Islands are now strengthening
further out from Hainan Island with Beijing’s recent oil-rig gambit in South China Sea, and
its routine patrols of the Senkaku/Diaoyu Islands are now an accepted fact on the ground.
As long as these salami-slicing tactics continue to yield results, it seems unimaginable that
Beijing will resort to the brazen actions that would reasonably trigger an ASB response from
Washington. Thus, for ASB to regain a sense of relevance, the United States and its allies
must first find an answer to Beijing’s salami-slicing tactics. Put differently: until China finds
it cannot achieve its goals through salami slicing, it will not resort to the higher spectrum
conflict that ASB was designed to deter or defeat.80
Another observer states that
Until quite recently, China’s aggressive moves in the South China Sea were widely viewed
as the product of an erratic foreign policy driven by competing agencies in which hawkish
players usually came out on top....
But the latest Chinese moves that have so alarmed the U.S. and China’s neighbors... appear
to be the result not of policy confusion but deliberate planning, say Chinese and foreign
security analysts. They are most likely coordinated at the highest level. Ultimately, they
seem to bear the stamp of the country’s president, Xi Jinping....
On the surface, this may look reckless. But one theory gaining traction among senior
officials and policy analysts around Asia and in Washington is that the timing is well
calculated. It reflects Mr. Xi’s belief that he is dealing with a weak U.S. president who won’t
push back, despite his strong rhetorical support for Asian allies.
Mr. Xi’s perception, say these analysts, has been heightened by U.S. President Barack
Obama’s failure to intervene militarily in Syria and Ukraine. And it’s led him to conclude
that he has a window of opportunity to aggresively assert China’s territorial claims around
the region.81
Two other observers state that
what is happening in the South China Sea is actually far more dangerous than what has come
before—and the forces driving it go well beyond pursuit of energy riches. The United States
needs to face up to the full magnitude of the Chinese challenge to have any hope of
successfully confronting it. This means not only tough talk but also a willingness to take
difficult action....
The United States has said it won’t take a stand on the sovereignty dispute and has called on
the two parties to resolve their differences peacefully. This is not enough: The United States
ought to call China’s bluff and make clear the real stakes. The United States and the

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Association of Southeast Asian Nations (ASEAN) should present a unified front in refusing
to recognize unilateral assertions of claims in disputed territories.
Even more important, the United States must be prepared to give life to its rhetorical
position. Although it does not have a treaty obligation to defend Vietnam, its rebalancing to
Asia is premised on its role as the primary guarantor of stability in the Pacific. Chinese
actions challenge that.
Vietnam has reiterated its commitment to peacefully resolve the dispute. If China does not
reciprocate, the United States should be prepared to offer support to Vietnam through an
increased naval presence. This would give Washington the ability to assess Chinese
capabilities and to help de-escalate the situation. Other options, such as restrictions on
CNOOC’s activities in the United States, could also be considered. If the United States can’t
back up its words with actions, its credibility in promising to uphold peace and stability in
the region will be gutted.82
Another observer states:
These are times of mounting drama and tension in the long power play of China’s rise in
Asia. Thus, it is more important than ever for American policy makers to peer behind the
curtain to see when rising-power loneliness is dressed as leadership and when confidence is a
mask for insecurity....
The Asian strategic order may now be in play; its U.S.-led character is under question, but
this is a complex, multilayered game. If China is seeking to rattle America and others—
especially Japan, the Philippines and Vietnam—it may be miscalculating. In the long run, the
premature displays of confidence China has lately shown are likely to harm its interests more
than advance them....
Under question is the region’s capacity to craft an order that is at once stable and free from
domination by a single power. If China’s latest behavior and rhetoric can partly be explained
by an excess of the wrong sort of confidence—premature, misjudged or a conduit for
nationalism—then the United States, its allies and partners will need to be firm, yet also
careful and nimble, in how they push back. Somehow, the message needs to reach China’s
security decision makers that their continued risk-taking could have consequences they
cannot control.
What the region requires is a new kind of balance—not of power or of resolve, but of
uncertainty. Of late, too much of the uncertainty has been in the minds of America’s Asian
allies and partners. Turning this situation around may be a first step towards China’s
acceptance that it will have to live up to its ‘win-win’ rhetoric when dealing with all its
neighbors. In other words, what is needed now is greater uncertainty among China’s strategic
decision makers about how the United States, Japan and the region’s middle powers will
respond to—or anticipate—the next coercive move.
Beijing may pretend to shrug off one legal action, but will have trouble sustaining its
indifference if Vietnam or additional South China Sea claimants also seek international
arbitration with the overt blessing of the United States, the European Union and other
champions of a rules-based international system. Stability in the South China Sea, a global
shipping artery, is every trading nation’s business. So Washington would be well advised to

follow the kind of practical action plan recently advanced by security policy expert Ely
Ratner, involving a coordinated assertion of rules-based management of maritime disputes,
globally through the G7, as well as regionally through the East Asia Summit [see next item
below]. Simultaneously, the United States and its allies, including Japan, are in their rights to
signal that they will expand security capacity-building, training and intelligence-sharing
when Southeast Asian states invite them to do so in response to new anxieties about China’s
actions.
Shifting the balance of uncertainty in Asia need not have a principally military dimension.
Even with constrained resources, the U.S. Navy can sustain a visible presence in the South
China Sea and, by invitation, in the territorial seas and exclusive economic zones of partners
and allies. New anxieties about regional stability will encourage more countries to join U.S.-
led maritime exercises and surveillance cooperation throughout the Indo-Pacific. This need
not amount to provocation, if combined with persistent invitations for China to begin serious
risk-reduction dialogue so that close encounters like the December 2013 USS Cowpens
incident become less likely to occur or escalate. The truth is, China’s maritime assertiveness
in recent years has not risen relentlessly. Notably, the tempo of sea and air incidents against
Japan—though still troubling—has eased this year; the disciplined pushback by Japan’s
experienced maritime forces may well be a factor. Beneath the bluster, at least some of
China’s security actors must know they cannot be the masters of infinite risk. This will be a
long drama and the script is not theirs alone to write.83
Another observer states:
American aspirations for China’s rise have gone terribly off-script. For decades, U.S. policy
toward China has comprised a dual-track “hedging” strategy that includes engaging Beijing
in an effort to induce China to support the existing international order, accompanied by a
balancing component in which the United States and its allies deter Beijing from choosing an
aggressive path. But now this strategy is coming apart at both ends: China neither accepts the
territorial realities of Asia, nor is it deterred from coercive acts of revisionism.
The real problem is that China’s bullying will endure as long as no one gets in the way. Why
wouldn’t it? Beijing is pushing on an open door, incurring few tangible costs for its
assertiveness and appearing to believe (perhaps rightly so) that it can ride out whatever
regional criticism arises in response. Based on its track record of the last several years, it’s
understandable that Beijing remains confident that most countries in the region will, at the
end of the day, be unwilling to imperil their economic relationship with China.
Alarm bells ought be ringing more loudly in Washington. Ultimately, it will be up to the
United States to staunch China’s mounting revisionism. But this will first require a sober
recognition that the old theories of how to shape China’s rise aren’t working. This is a
difficult conversation to have in Washington because acknowledging Chinese behavior for
what it is—undeterred and unapologetic assertiveness—will necessitate a more serious
American response than we have seen to date.
This doesn’t mean forgoing the cooperative elements of the “hedge” and committing to a
highly competitive relationship with China. We’re not there yet. And besides, there’s a big
difference between determining that China is presently undeterred versus determining that it
is patently undeterrable. Before definitively drawing the latter conclusion, the immediate task
for U.S. policymakers is to test the elasticity of Chinese decision-making.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

This calls for greater attention to cost-imposition strategies that attempt to shape the relative
value of continued revisionism for China. Washington will have to explore the full potential
range of economic, military, diplomatic and political points of leverage over Beijing (and
there are many) to increase the costs of Chinese assertiveness, including areas that directly
impinge on the interests of China’s leaders. The United States will also have to develop more
tailored options for responding directly to maritime coercion in ways that repel specific acts
of revisionism, rather than simply exacting lateral forms of punishment after the fact.
China’s slow but steady revisions to the territorial status quo in Asia are not a legacy the
Obama administration wants to leave behind. Being more proactive in stemming this
behavior represents the principal challenge for Washington’s China policy today.84
Another observer states:
In the case of China trying to support its territorial claims, I think there’s an upper limit on
what it will do. Below that limit, though, the Chinese are sitting around, thinking, “Now,
what can I do next? Let’s see, I can extend the ADIZ (Air Defense Identification Zone), I can
declare a new fishing zone, etc. ….”
They’re coming up with all sorts of gray-zone challenges, and they’re going to keep on doing
so. We have to figure out how to counter those actions. You can’t just sit there and react to
what the Chinese are doing. Of course, you need to think them through carefully, but if the
Chinese want to play a game of “I’ll poke you here, and I’ll poke you there,” then you have
to respond and say, “Game on.” Japan, the Philippines and Vietnam need to take initiatives
of their own and be equally forceful in that space.85
Comments by Some Observers Suggesting Elements of a U.S. Strategy
One observer, proposing series of actions for the United States to take during the summer months
of 2014, states:
It’s time to breathe new life into U.S. policy in the South China Sea. Despite important
initiatives by the Obama administration to strengthen bilateral security ties, build partner
capacity and enhance multilateral cooperation, the region’s territorial and maritime disputes
continue to engender dangerous crises. The potential for armed conflict will only grow larger
in the absence of creative and decisive U.S. leadership....
The costs for the United States of failing to play an innovative leadership role could be
enormous. Against this backdrop, the coming months provide a series of critical
opportunities for top-level U.S. officials to evolve and advance U.S. policy. Below is a
proposed calendar for launching four new initiatives that are practical, feasible and would
support U.S. interests in the region....
At the Shangri-La Dialogue in Singapore at the end of May, Secretary Hagel should propose
in concept the development of a multilateral MDA initiative. In concert, the National
Security Council staff should lead an interagency working group to offer recommendations
related to cost, operational requirements and intelligence sharing. The administration should

also consider potential groupings of allies and partners, including (but not limited to) an
ASEAN-centered architecture....
At the G-7 summit in Brussels in June, President Obama should propose to include language
in the summit’s joint statement supporting the legitimacy of international arbitration to
manage maritime disputes in the South China Sea....
Beginning at the U.S.-China Strategic Security Dialogue in August, the United States should
make clear in private that it expects China to withdraw its occupation of the disputed feature
by the end of 2014 and return to the pre-April 2012 status quo. If necessary, this message can
be repeated publicly in ASEAN-centered regional forums later in the year, including the East
Asia Summit in Burma in November. The United States military should also consider
conducting freedom of navigation operations in areas surrounding the reef to underscore that
the United States does not recognize Chinese administration....
Secretary Kerry should propose the idea of an “early harvest” of the COC at the ASEAN
Regional Forum in August and, with guidance from the U.S. Mission to ASEAN in Jakarta,
propose specific components of the COC discussions that are widely agreed-upon and ripe
for immediate implementation.86
Two other observers, proposing a U.S. strategy for the South China Sea, states:
The United States should develop and promulgate a National Strategy for the South China
Sea (NSSCS) as part of its ongoing efforts to counter Chinese aggression in the region and to
resolve the disputes there in a peaceful manner. It behooves the United States to shift its
current posture in the South China Sea from one of vigilant maintenance of the status quo to
a position that will foster the peaceful management and ultimately permanent resolution of
issues affecting U.S. navigational rights and interests in the region. An NSSCS is one
effective means of producing the necessary shift....
Specifically, the U.S. should:
1. Take an official position regarding disputed SCS land features....
2. Underscore U.S. policy on military activities in the SCS....
3. Continue freedom-of-navigation protests and naval operations....
4. Publish a “Limits in the Seas” report regarding the nine-dash line....
5. Assist SCS nations in complying with the law of the sea....
6. Support arbitration cases against China....
7. Preempt potentially harmful provisions of an SCS “code of conduct.”87

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Beijing is opportunistically seeking to flex its newfound muscle and make the 9-dash line a
de facto and de jure reality. In effect, China wants the South (and East) China Sea as an
inland lake. The placement of [the] HS-981 [oil rig] is part of a disturbing pattern of
aggressive Chinese behavior. Another ongoing resort to “tailored coercion” is the
reclamation of small land features in the Spratly Islands. Recently released photographs
taken in March show China’s reclamation of Johnson South Reef, the site of a 1988
Vietnam-China naval skirmish. Although China is not alone is seeking to advance its
territorial claims and maritime interests, its behavior is uniquely escalatory. US Secretary of
Defense Chuck Hagel singled out China’s “destabilizing, unilateral actions” against its
maritime neighbors at this year’s Shangri-La Dialogue in Singapore.
The placement of [the] HS-981 [oil rig], coming after diplomatic exertions to improve
Beijing-Hanoi ties, is perplexing to many in the region. But China’s gambit in its near seas
involves dialing up and dialing down coercive diplomacy. As part of a renewed focus on
“periphery diplomacy,” China is rewarding neighbors willing to work with Beijing, and is
seeking to isolate those who resist China’s unilateral demands. Such actions are tailored to
be sufficiently peaceful so as not to escalate into full-fledged conflict or to trigger a unified,
anti-China alliance; they are tailored to appear sufficiently non-military in nature and thus
not intended to accentuate China’s rapidly modernizing military forces; and they are tailored
to send varying messages to different audiences—internal, regional, and international.
China’s tailored coercion is aimed not just at its neighbors but also at the United States.
China wants to coerce the United States to tamp down the national exuberance of its allies
and partners, from the Philippines and Japan (in the East China Sea), to Vietnam and
Malaysia. Notwithstanding China’s coercive behavior, the United States needs to persevere
in building an open, rules-based system in the Asia-Pacific region. But in the meantime, it
also needs to find a way to address Chinese incremental aggression, often likened to salami
slicing. In the present SCS crisis, the United States needs to bolster its ties with Vietnam to
help impose costs on China. Taking together the twin US goals of regional security
maintenance and order building, and focusing on countering China’s use of coercion to
unilaterally alter the status quo, there are five priorities that deserve attention from both
Hanoi and Washington, and the region in general.
First, as part of the burgeoning US-Vietnam security dialogue, the two countries should
focus on developing cost-imposition strategies that might dissuade China from resorting to
unilateral changes to the status quo or impose stiff penalties for bad behavior.
Cost-
imposition strategies can be direct and indirect, military and non-military, short-term and
long-term. But they should be feasible, cost-effective, and meaningful. Vietnam needs to
send top-level officials to Washington to underscore the importance of this dialogue.
Second, there should be more frequent and larger bilateral exercises and US military
deployments to Vietnam under the existing shared membership in the Proliferation Security
Initiative (PSI).
Through PSI, the United States can provide a reassuring presence without
taking on the burdens, costs and risks of trying to restore a permanent military base. At the
same time, greater US-Vietnam cooperation can improve the professionalism of Vietnamese
defenses and the capacity for combined action. Improving maritime domain awareness is an
objective that supports both PSI and would have benefits for the early detection of
misbehavior in the East Sea.
Third, the United States should support triangular dialogue and practical cooperation
among other SCS claimant states, especially Vietnam, Malaysia and the Philippines.
The
United States can support this dialogue through regional multilateral forums such as the
ASEAN Regional Forum, the ASEAN Defense Ministers’ Meeting Plus and the East Asia
Summit. Washington can also encourage other US allies and partners (Japan, South Korea,
Australia, India and other members of ASEAN) to offer assistance with training and
education, equipment and information sharing. The United States should encourage Japan,
Congressional Research Service

which is already providing coast guard patrol vessels beginning next year, and India, which
operates Russian submarines, to assist the Vietnamese navy to operate and deploy Russian
Kilo-class submarines. As Vietnam incorporates six submarines into its small navy, others
need to help Vietnam establish operational independence.
Fourth, the United States should end the ban on lethal arms sales to Vietnam. The scope and
kind of direct military support can still be linked to demonstrable improvements in human
rights. But it is now time to begin limited arms sales that are useful for countering tailored
coercion. Such systems could improve maritime domain awareness and bolster defensive if
still potentially lethal means of punishing any attacker. Torpedoes and short-range cruise
missiles would strengthen deterrence, and a potential aggressor would think twice before
using overt coercion or limited force to make its claims.
Fifth, the United States should press Vietnam and other ASEAN members to support specific
rules for maintaining good order at sea and preserve the freedom of the global commons in
the South China Sea.
Specific steps that might eventually be part of a binding code of
conduct should be promoted and put into practice as soon as possible. International
arbitration over UNCLOS provisions should be embraced. Land features should be
systematically cataloged and defined to develop a shared regional understanding of what
land features are islands and which are rocks.
These steps are illustrative of a broader tool kit at the disposal of officials in Vietnam, the
United States and the region to impose costs on bad behavior and provide safeguards for
complying with mutually agreed rules. They are necessary because of China’s increasing
reliance on coercion. At the same time, it is vital to further develop a roadmap with China on
how to avert dangerous incidents and manage strategic competition. Through these steps,
tailored coercion can be prevented from becoming the accepted norm in the South China
Sea.88
Some Reported U.S. Actions
A December 16, 2013, State Department fact sheet states:
On December 16, Secretary of State John Kerry announced an initial commitment of $32.5
million in new regional and bilateral assistance to advance maritime capacity building in
Southeast Asia. Including this new funding, our planned region-wide funding support for
maritime capacity building exceeds $156 million for the next two years.
As an example of our commitment to strengthen maritime capacities in Southeast Asia, the
United States intends to provide up to $18 million in new assistance to Vietnam to enhance
the capacity of coastal patrol units to deploy rapidly for search and rescue, disaster response,
and other activities, including through provision of five fast patrol vessels in 2014 to the
Vietnamese Coast Guard. This assistance directly responds to priorities identified in the Joint
Minutes on Vietnam and U.S. Coast Guard Maritime Cooperation signed October 1, 2013,
by VCG Major General Nguyen Quang Dam and USCG Commandant Admiral Robert J.
Papp, Jr.
The United States will also expand its support for regional cooperation by strengthening
information sharing among national agencies in Southeast Asia charged with maritime
security and maritime law enforcement. Building on existing programs and initiatives, we

will increase training for maritime law enforcement officials from participating Southeast
Asian countries in multilateral settings, such as currently occurs in the Gulf of Thailand
initiative and Trilateral Interagency Maritime Law Enforcement Workshops. We will take
advantage of the International Law Enforcement Academy in Bangkok, Thailand, to deliver
new maritime law enforcement training courses for maritime officials across Southeast Asia.
The Secretary’s announcement builds upon the United States’ longstanding commitment to
support the efforts of Southeast Asian nations to enhance security and prosperity in the
region, including in the maritime domain. Existing programs include efforts to combat piracy
in and around the Malacca Strait, to counter transnational organized crime and terrorist
threats in the tri-border region south of the Sulu Sea between the southern Philippines,
Indonesia, and Malaysia, and to expand information sharing and professional training
through the Gulf of Thailand initiative. In addition, since 1999 the U.S.-supported
International Law Enforcement Academy in Bangkok, Thailand has been one of the world’s
premier multilateral platforms for law enforcement training and cooperation.89
A March 30, 2014, press report states:
Japan and the United States plan to create a permanent consultative body to coordinate the
operations of the Self-Defense Forces and the U.S. military in the face of China’s
highhanded actions over the Senkaku Islands in Okinawa Prefecture, Japanese and U.S.
government sources said.
The envisaged body is expected to help Japan and the United States deal quickly with
situations in and around the islands that cannot be clearly identified as armed attacks, the
sources said.
Establishment of the consultative body will be included in revisions to the Guidelines for
Japan-U.S. Defense Cooperation scheduled for the end of the year....
During their talks to review the current guidelines, foreign and defense officials from both
sides stated that there is a need to create a permanent coordination body when they went over
desktop military exercises and exchanged opinions on how quasi-military attacks on Japan
should be handled.
Experts predict that an attempt by China to seize the Senkakus would very likely begin with
the landing of armed personnel disguised as fishermen. The prediction has prompted the
Japanese side to demand enhancement of the Japan-U.S. partnership to deal with such
ambiguous situations.90
In assessing the question of U.S. strategy for countering China’s salami-slicing strategy, one
potential matter that Congress may consider concerns the relatively limited ability of the
Philippines’ to patrol its EEZ, which includes Scarborough Shoal and some of the Spratly Islands
(see Figure 4), and to otherwise assert and defend its maritime claims. The Philippines has
relatively few modern ships larger than patrol craft in its navy or coast guard, and the country’s
resulting limited capability for patrolling the EEZ and otherwise asserting and defending its

Congressional Research Service

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

maritime claims can be viewed as contributing to a power vacuum in the SCS that China can
exploit in asserting and defending its maritime territorial claims in the area.91
The United States has taken certain actions to improve the Philippines’ ability for patrolling its
EEZ and otherwise asserting and defending its maritime claims, including the transfer of two ex-
U.S. Coast Guard Hamilton-class cutters to the Philippines’ navy. The United States and the
Philippines have also signed an agreement that will provide increased access to Philippine bases
for U.S. forces. The Philippines also plans to acquire two new frigates from Italy, a used frigate
from South Korea,92 10 patrol boats from Japan, and additional aircraft.93 Whether these and other
additions will give the Philippines a sufficient capability for patrolling its EEZ and otherwise
asserting and defending its maritime claims is not clear. Potential follow-on questions for
Congress include the following:
• Will the Philippines’ current plans for acquiring new ships and aircraft give the
Philippines a sufficient capability for patrolling its EEZ and otherwise asserting
and defending its maritime claims?
• If not, what would be the potential advantages or disadvantages of initiating a
U.S. or multilateral program for providing the Philippines with additional ships
and aircraft? What might such a program look like? As part of its FY2015 budget
submission, for example, the U.S. Navy is proposing to retire all 10 of its
remaining Oliver Hazard Perry (FFG-7) class frigates. Other ships in this class
that have been removed from U.S. Navy service have in some cases have been
transferred to other countries. Should some or all of these 10 frigates be
transferred to the Philippines as part of a program that also provided support for
training crews and for establishing logistics and maintenance support facilities
for these ships?
Risk of United States Being Drawn Into a Crisis or Conflict
Another potential issue for Congress concerns U.S. actions to reduce the risk that the United
States might be drawn into a crisis or conflict over a territorial dispute involving China. Potential
oversight questions for Congress include the following:
• Have U.S. officials taken appropriate and sufficient steps to help reduce the risk
of maritime territorial disputes in the SCS and ECS escalating into conflicts?
• Do the United States and Japan have a common understanding of potential U.S.
actions under Article IV of the U.S.-Japan Treaty on Mutual Cooperation and
Security in the event of a crisis or conflict over the Senkaku Islands? What steps
has the United States taken to ensure that the two countries share a common
understanding?

91 Limitations on Vietnamese and Malaysian capabilities can also be viewed as contributing to such a power vacuum;

• Do the United States and the Philippines have a common understanding of how
the 1951 U.S.-Philippines mutual defense treaty applies to maritime territories in
the SCS that are claimed by both China and the Philippines, and of potential U.S.
actions under Article IV of the treaty in the event of a crisis or conflict over the
territories? What steps has the United States taken to ensure that the two
countries share a common understanding?
• Aside from public statements, what has the United States communicated to China
regarding potential U.S. actions under the two treaties in connection with
maritime territorial disputes in the SCS and ECS?
• Has the United States correctly balanced ambiguity and explicitness in its
communications to various parties regarding potential U.S. actions under the two
defense treaties?
• How do the two treaties affect the behavior of Japan, the Philippines, and China
in managing their territorial disputes? To what extent, for example, would they
help Japan or the Philippines resist potential Chinese attempts to resolve the
disputes through intimidation, or, alternatively, encourage risk-taking or
brinksmanship behavior by Japan or the Philippines in their dealings with China
on the disputes? To what extent do they deter or limit Chinese assertiveness or
aggressiveness in their dealings with Japan the Philippines on the disputes?
• Has the DOD adequately incorporated into its planning crisis and conflict
scenarios arising from maritime territorial disputes in the SCS and ECS that fall
under the terms of the two treaties?
Whether United States Should Enter Into A U.S.-Chinese
Incidents-at-Sea (INCSEA) Agreement

Another potential issue for Congress is whether the United States should seek to reduce the risk
of future incidents between U.S. and Chinese ships and aircraft in China’s EEZ by entering into
an agreement with China regulating the behavior of U.S. Chinese ships and aircraft that are
operating in proximity with one another. Such an agreement could be broadly similar to the May
1972 U.S.-Soviet agreement on the prevention of incidents on and over the high seas, commonly
known as the Incidents-at-Sea (INCSEA) agreement.94
Supporters of this option could argue the following:
• The May 1972 U.S.-Soviet INCSEA agreement is regarded by observers as
having been successful in helping to reduce the risk of incidents between U.S.
and Soviet ships and aircraft during the Cold War.
• A broadly similar agreement with China could reduce the risk of incidents
involving U.S. and Chinese ships and aircraft, and could be useful in that regard
as a confidence-building measure.

94 23 UST 1168; TIAS 7379; UNTS 151. The agreement was signed at Moscow on May 25, 1972, and entered into
force the same day.
Congressional Research Service
45

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

• The terms of such an agreement could be drafted to be consistent with the U.S.
position on whether a coastal state has the right to regulate foreign military forces
operating in their EEZs.
Opponents of this option could argue the following:
• When the May 1972 U.S.-Soviet INCSEA agreement was signed, the October
1972 multilateral convention on the international regulations for preventing
collisions at sea (commonly known as the COLREGs or the “rules of the road”)95
(see discussion in “Background”) did not yet exist. In contrast to the situation in
May 1972, the COLREGs convention now exists, and both China and the United
States are party to it. China and the United States are also party to the 2014 Code
for Unplanned Encounters at Sea (CUES) and the 1998 bilateral U.S.-Chinese
Military Maritime Consultative Agreement (MMCA), which is aimed at reducing
the chances of confrontation between the two countries’ militaries at sea and in
the air.96 Managing U.S.-Chinese interactions at sea requires standards to govern
conduct and a forum to discuss incidents. A new INCSEA-like agreement is not
necessary, because both of these things are already in place: The COLREGs and
CUES provide the standards, and the consultative mechanism created by the
MMCA creates the forum.
• Chinese vessels arguably violated both the COLREGs and Article 94 of
UNCLOS in the 2009 incident with a U.S. ship.97 The Chinese ship involved in
the December 5, 2013, incident involving the Cowpens might have violated the
COLREGs.98 Consequently, signing a new INCSEA-like agreement with China
could be viewed as rewarding China for past violations and be of questionable

Related potential oversight questions for Congress include the following:
• Is the number of countries that share China’s view on whether coastal states have
a right under UNCLOS to regulate the activities of foreign military forces in their
EEZs growing, and if so, what steps is the Administration taking to stop or

reverse this growth? What activities is the Administration taking, vis-a-vis China
or other countries, to reinforce the U.S. position on whether coastal states have a
right under UNCLOS to regulate the activities of foreign military forces in their
EEZs?
• One of the 27 countries listed earlier (see “Dispute Regarding China’s Rights
Within Its EEZ”) as having restrictions inconsistent with UNCLOS that would
limit the exercise of high seas freedoms by foreign navies beyond 12 nautical
miles from the coast is Portugal. Given Portugal’s status as a NATO ally and a
historical maritime power, to what extent do Portugal’s restrictions make it more
difficult for the United States to defend its position on the question of whether
coastal states have the right to regulate foreign military activities in their EEZs?
What steps has the Administration taken to encourage Portugal, as a NATO ally
that derives collective security benefits from U.S. defense efforts, to end its
restrictions and affirm the U.S. position on the question of whether coastal states
have the right to regulate foreign military activities in their EEZs?
• Another one of the 27 countries listed earlier is Thailand—a country with a coast
on the Gulf of Thailand, a body of water that opens onto the South China Sea.
Given Thailand’s status as the United States’ oldest ally in Southeast Asia (as
described by DOD) and as the host country for the annual Cobra Gold exercise,
the United States’ longest-standing military exercise in the Pacific,100 what steps
has the Administration taken to encourage Thailand to end its restrictions that
would limit the exercise of high seas freedoms by foreign navies beyond 12
nautical miles from the coast and affirm the U.S. position on the question of
whether coastal states have the right to regulate foreign military activities in their
EEZs?
• Another one of the 27 listed earlier is Vietnam—a country whose relations with
the United States have improved in recent years, in part because of China’s
activities in the SCS. What steps has the Administration taken to encourage
Vietnam to end its restrictions that would limit the exercise of high seas freedoms
by foreign navies beyond 12 nautical miles from the coast and affirm the U.S.
position on the question of whether coastal states have the right to regulate
foreign military activities in their EEZs?
• China in recent years has begun to operate small numbers of navy ships in the
Indian Ocean (for anti-piracy operations), the Persian Gulf, and the
Mediterranean Sea. Chinese officials are also concerned about the security of
their maritime oil supply routes from the Persian Gulf. To what extent have U.S.
officials communicated to Chinese officials that, in light of these developments,
China arguably has an increasing interest in changing its position on whether
coastal states have a right under UNCLOS to regulate the activities of foreign
military forces in their EEZs?

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Whether United States Should Ratify United Nations Convention
on the Law of the Sea (UNCLOS)

Another issue for Congress—particularly the Senate—is the impact of maritime territorial and
EEZ disputes involving China on the overall debate on whether the United States should become
a party to UNCLOS. UNCLOS was adopted by Third United Nations Conference on the Law of
the Sea in December 1982, and entered into force in November 1994. The treaty established
EEZs as a feature of international law, and contains multiple provisions relating to territorial
waters and EEZs. As of September 21, 2012, 162 nations were party to the treaty, including China
and most other countries bordering on the SCS and ECS (the exceptions being North Korea and
Taiwan).101
The treaty and an associated 1994 agreement relating to implementation of Part XI of the treaty
(on deep seabed mining) were transmitted to the Senate on October 6, 1994.102 In the absence of
Senate advice and consent to adherence, the United States is not a party to the convention and the
associated 1994 agreement. During the 112th Congress, the Senate Foreign Relations Committee
held four hearings on the question of whether the United States should become a party to the
treaty on May 23, June 14 (two hearings), and June 28, 2012.
Supporters of the United States becoming a party to UNCLOS argue or might argue one or more
of the following:
• The treaty’s provisions relating to navigational rights, including those in EEZs,
reflect the U.S. position on the issue; becoming a party to the treaty would help
lock the U.S. perspective into permanent international law.
• Becoming a party to the treaty would give the United States greater standing for
participating in discussions relating to the treaty—a “seat at the table”—and
thereby improve the U.S. ability to call on China to act in accordance with the
treaty’s provisions, including those relating to navigational rights, and to defend
U.S. interpretations of the treaty’s provisions, including those relating to whether
coastal states have a right under UNCLOS to regulate foreign military activities
in their EEZs.103
• At least some of the ASEAN member states want the United States to become a
member of UNCLOS, because they view it as the principal framework for
resolving maritime territorial disputes.
• Relying on customary international law to defend U.S. interests in these issues is
not sufficient, because it is not universally accepted and is subject to change over
time based on state practice.

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Opponents of the United States becoming a party to UNCLOS argue or might argue one or more
of the following:
• China’s ability to cite international law (including UNCLOS) in defending its
position on whether coastal states have a right to regulate foreign military
activities in their EEZs104 shows that UNCLOS does not adequately protect U.S.
interests relating to navigational rights in EEZs; the United States should not help
lock this inadequate description of navigational rights into permanent
international law by becoming a party to the treaty.
• The United States becoming a party to the treaty would do little to help resolve
maritime territorial disputes in the SCS and ECS, in part because China’s
maritime territorial claims, such as those depicted in the map of the nine-dash
line, predate and go well beyond what is allowed under the treaty and appear
rooted in arguments that are outside the treaty.
• The United States can adequately support the ASEAN countries and Japan in
matters relating to maritime territorial disputes in the SCS and ECS in other
ways, without becoming a party to the treaty.
• The United States can continue to defend its positions on navigational rights on
the high seas by citing customary international law, by demonstrating those rights
with U.S. naval deployments (including those conducted under the FON
program), and by having allies and partners defend the U.S. position on the EEZ
issue at meetings of UNCLOS parties.

SEC. 1257. SENSE OF CONGRESS ON MILITARY CAPABILITIES OF THE PEOPLE’S
REPUBLIC OF CHINA.
Congress—
(1) notes the People’s Republic of China (PRC) continues to rapidly modernize and expand
its military capabilities across the land, sea, air, space, and cyberspace domains;

H.R. 772
H.R. 772 was introduced in the House on February 15, 2013. The text of H.R. 772 as
introduced is as follows:
A BILL
To promote peaceful and collaborative resolution of the South China Sea dispute.
Be it enacted by the Senate and House of Representatives of the United States of America in
Congress assembled,
SECTION 1. FINDINGS.
Congress finds the following:
(1) The South China Sea contains vital commercial shipping lanes and points of access
between the Indian Ocean and Pacific Ocean, providing a maritime lifeline to India,
Singapore, Malaysia, Indonesia, the Philippines, Vietnam, Brunei, Taiwan, Japan, and the
Korean peninsula.
(2) China, Vietnam, the Philippines, Taiwan, Malaysia, and Brunei have disputed territorial
claims over the Spratly Islands, and China, Taiwan, and Vietnam have disputed territorial
claims over the Paracel Islands.
(3) In 2009, the Government of the People’s Republic of China submitted to the United
Nations a map with the 9-dotted line (also known as the Cow Tongue line) which raised
questions about whether China officially claims most of the 1,423,000 square miles of the
South China Sea, more than any other nation involved in these territorial disputes.
(4) In November 2012, China began to include a map of its territorial claims inside its
passports, despite the protests of its neighbors, including Vietnam and the Philippines.
(5) Although not a party to these disputes, the United States has a national economic and
security interest in maintaining peace, stability, and prosperity in East Asia and Southeast
Asia, and ensuring that no party threatens or uses force or coercion unilaterally to assert
maritime territorial claims in East Asia and Southeast Asia, including in the South China
Sea, the East China Sea, or the Yellow Sea.
(6) The Association of Southeast Asian Nations (ASEAN) has promoted multilateral talks in
disputed areas without settling the issue of sovereignty.
(7) In 2002, ASEAN and China signed a Declaration on the Conduct of Parties in the South
China Sea.
(8) That declaration committed all parties to those territorial disputes to `reaffirm their
respect for and commitment to the freedom of navigation in and over flight above the South
China Sea as provided for by the universally recognized principles of international law’, and
Congressional Research Service
54

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

to `resolve their territorial and jurisdictional disputes by peaceful means, without resorting to
the threat or use of force’.
(9) In July and November of 2010, the United States and our Republic of Korea allies
conducted joint naval exercises in the Yellow Sea in international waters, as well as Republic
of Korea territorial waters, in the vicinity of the site of the March 2010 North Korean attack
on the South Korean military vessel Cheonan, these exercises drew objections from Beijing
over foreign operations in the Yellow Sea.
(10) In September 2010, tensions were raised in the East China Sea near the Senkaku
(Diaoyutai) Islands, a territory under the legal administration of Japan, when a Chinese
fishing vessel deliberately rammed Japanese Coast Guard patrol boats.
(11) On February 25, 2011, a frigate from China’s navy fired shots at 3 fishing boats from
the Philippines.
(12) On March 2, 2011, the Government of the Philippines reported that two patrol boats
from China attempted to ram one of its surveillance ships.
(13) On May 26, 2011, a maritime security vessel from China cut the cables of an
exploration ship from Vietnam, the Binh Minh, in the South China Sea in waters near Cam
Ranh Bay in the exclusive economic zone of Vietnam.
(14) On May 31, 2011, three Chinese military vessels used guns to threaten the crews of four
Vietnamese fishing boats while they were fishing in the waters of the Truong Sa (Spratly)
archipelago.
(15) On June 3, 2011, Vietnam’s Foreign Ministry released a statement that `Vietnam is
resolutely opposed to these acts by China that seriously violated the sovereign and
jurisdiction rights of Viet Nam to its continental shelf and Exclusive Economic Zone (EEZ)’.
(16) On June 9, 2011, three vessels from China, including one fishing vessel and two
maritime security vessels, ran into and disabled the cables of another exploration ship from
Vietnam, the Viking 2, in the exclusive economic zone of Vietnam.
(17) The actions of the Government of the People’s Republic of China in the South China
Sea have also affected United States military and maritime vessels and aircraft transiting
through international air space and waters, including the collision of a Chinese fighter plane
with a United States surveillance plane in 2001, the harassment of the USNS Victorious and
the USNS Impeccable in March 2009, and the collision of a Chinese submarine with the
sonar cable of the USS John McCain in June 2009.
(18) On July 23, 2010, former Secretary of State Hillary Rodham Clinton stated at the
ASEAN Regional Forum that the United States, like every nation, has a national interest in
freedom of navigation, open access to Asia’s maritime commons, respect for international
law, and unimpeded commerce in the South China Sea.
(19) On June 23, 2011, the United States stated that it was ready to provide hardware to
modernize the military of the Philippines.
(20) The United States and the Philippines conducted combined naval exercises in the Sulu
Sea, near the South China Sea, from June 28 to July 8, 2011.
Congressional Research Service

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

(21) On July 22, 2011, an Indian naval vessel, sailing about 45 nautical miles off the coast of
Vietnam, was warned by a Chinese naval vessel that it was allegedly violating Chinese
territorial waters.
(22) In June 2012, China’s cabinet, the State Council, approved the establishment of the city
of Sansha to oversee the areas claimed by China in the South China Sea.
(23) In July 2012, Chinese military authorities announced that they had established a
corresponding Sansha garrison in the new prefecture.
(24) On June 23, 2012, the China National Offshore Oil Corporation invited bids for oil
exploration in areas within 200 nautical miles of the continental shelf and within the
exclusive economic zone of Vietnam.
(25) Since July 2012, Chinese patrol ships have been spotted near the disputed Senkaku
(Diaoyutai) Islands in the East China Sea.
(26) At the July 2012 ASEAN Regional Forum, former Secretary of State Clinton said, `We
believe the nations of the region should work collaboratively and diplomatically to resolve
disputes without coercion, without intimidation, without threats, and without the use of
force’.
(27) In November 2012, a regulation was approved by the Hainan People’s Congress
authorizing Chinese maritime police to `board, search’ and even `take over’ ships determined
to be `illegally entering’ South China Sea waters unilaterally claimed by Beijing.
(28) At a meeting with the Japanese Foreign Minister on January 18, 2013, former Secretary
of State Clinton stated that `although the United States does not take a position on the
ultimate sovereignty of the (Senkaku) islands, we acknowledge they are under the
administration of Japan’, adding that `We oppose any unilateral actions that would seek to
undermine Japanese administration, and we urge all parties to take steps to prevent incidents
and manage disagreements through peaceful means’.
(29) On August 3, 2012, a Department of State spokesperson expressed concern over
`China’s upgrading of the administrative level of Sansha City and the establishment of a new
military garrison there’, expressed encouragement for ASEAN and China `to make
meaningful progress toward finalizing a comprehensive Code of Conduct’, and called upon
claimants to `explore every diplomatic or other peaceful avenue for resolution, including the
use of arbitration or other international legal mechanisms as needed’.
SEC. 2. SENSE OF CONGRESS.
It is the sense of Congress that, in light of the congressional finding described above, the
Secretary of State should—
(1) reaffirm the strong support of the United States for the peaceful resolution of maritime
territorial disputes in the South China Sea, the Taiwan Strait, the East China Sea, and the
Yellow Sea and pledge continued efforts to facilitate a collaborative, peaceful process to
resolve these disputes;
(2) condemn the use of threats or force by naval, maritime security, and fishing vessels from
China in the South China Sea and the East China Sea as well as the use of force by North
Korea in the Yellow Sea that would escalate tensions or result in miscalculations;
Congressional Research Service
56

(3) note that overt threats and gun boat diplomacy are not constructive means for settling
these outstanding maritime disputes;
(4) welcome the diplomatic efforts of Association of Southeast Asian Nations (ASEAN) and
the United States allies and partners in Japan, the Republic of Korea, Taiwan, the
Philippines, and India to amiably and fairly resolve these outstanding disputes; and
(5) support the continuation of operations by the United States Armed Forces in support of
freedom of navigation rights in international waters and air space in the South China Sea, the
East China Sea, the Taiwan Strait, and the Yellow Sea.
SEC. 3. REPORT ON THE CODE OF CONDUCT FOR THE SOUTH CHINA SEA.
(a) Report- Not later than 180 days after the date of the enactment of this Act, the Secretary

disputes.
Whereas Asia-Pacific's maritime domains, which include both the sea and airspace above the
domains, are critical to the region's prosperity, stability, and security, including global
commerce;
Whereas the United States is a longstanding Asia-Pacific power and has a national interest in
maintaining freedom of operations in international waters and airspace both in the Asia-
Pacific region and around the world;
Whereas, for over 60 years, the United States Government, alongside United States allies and
partners, has played an instrumental role in maintaining stability in the Asia-Pacific,
including safeguarding the prosperity and economic growth and development of the Asia-
Pacific region;
Whereas the United States, from the earliest days of the Republic, has had a deep and
abiding national security interest in freedom of navigation, freedom of the seas, respect for
international law, and unimpeded lawful commerce, including in the East China and South
China Seas;

Maritime Territorial and Exclusive Economic Zone (EEZ) Disputes Involving China

Whereas the United States alliance relationships in the region, including with Japan, Korea,
Australia, the Philippines, and Thailand, are at the heart of United States policy and
engagement in the Asia-Pacific region, and share a common approach to supporting the
maintenance of peace and stability, freedom of navigation, and other internationally lawful
uses of sea and airspace in the Asia-Pacific region;
Whereas territorial and maritime claims must be derived from land features and otherwise
comport with international law;
Whereas the United States Government has a clear interest in encouraging and supporting the
nations of the region to work collaboratively and diplomatically to resolve disputes and is
firmly opposed to coercion, intimidation, threats, or the use of force;
Whereas the South China Sea contains great natural resources, and their stewardship and
responsible use offers immense potential benefit for generations to come;
Whereas the United States is not a claimant party in either the East China or South China
Seas, but does have an interest in the peaceful diplomatic resolution of disputed claims in
accordance with international law, in freedom of operations, and in the free-flow of
commerce free of coercion, intimidation, or the use of force;
Whereas the United States supports the obligation of all members of the United Nations to
seek to resolve disputes by peaceful means;
Whereas freedom of navigation and other lawful uses of sea and airspace in the Asia-Pacific
region are embodied in international law, not granted by certain states to others;
Whereas, on November 23, 2013, the People's Republic of China unilaterally and without
prior consultations with the United States, Japan, the Republic of Korea or other nations of
the Asia-Pacific region, declared an Air Defense Identification Zone (ADIZ) in the East
China Sea, also announcing that all aircraft entering the PRC's self-declared ADIZ, even if
they do not intend to enter Chinese territorial airspace, would have to submit flight plans,
maintain radio contact, and follow directions from the Chinese Ministry of National Defense
or face `emergency defensive measures';
Whereas the `rules of engagement' declared by China, including the `emergency defensive
measures', are in violation of the concept of `due regard for the safety of civil aviation' under
the Chicago Convention of the International Civil Aviation Organization's Chicago
Convention and thereby are a departure from accepted practice;
Whereas the Chicago Convention of the International Civil Aviation Organization
distinguishes between civilian aircraft and state aircraft and provides for the specific
obligations of state parties, consistent with customary law, to `refrain from resorting to the
use of weapons against civil aircraft in flight and . . . in case of interception, the lives of
persons on board and the safety of aircraft must not be endangered';
Whereas international civil aviation is regulated by international agreements, including
standards and regulations set by ICAO for aviation safety, security, efficiency and regularity,
as well as for aviation environmental protection;
Whereas, in accordance with the norm of airborne innocent passage, the United States does
not recognize the right of a coastal nation to apply its ADIZ procedures to foreign state
aircraft not intending to enter national airspace nor does the United States apply its ADIZ
procedures to foreign state aircraft not intending to enter United States airspace;

Whereas the United States Government expressed profound concerns with China's unilateral,
provocative, dangerous, and destabilizing declaration of such a zone, including the potential
for misunderstandings and miscalculations by aircraft operating lawfully in international
airspace;
Whereas the People's Republic of China's declaration of an ADIZ in the East China Sea will
not alter how the United States Government conducts operations in the region or the
unwavering United States commitment to peace, security and stability in the Asia-Pacific
region;
Whereas the Government of Japan expressed deep concern about the People's Republic of
China's declaration of such a zone, regarding it as an effort to unduly infringe upon the
freedom of flight in international airspace and to change the status quo that could escalate
tensions and potentially cause unintentional consequences in the East China Sea;
Whereas the Government of the Republic of Korea has expressed concern over China's
declared ADIZ, and on December 9, 2013, announced an adjustment to its longstanding Air
Defense Identification Zone, which does not encompass territory administered by another
country, and did so only after undertaking a deliberate process of consultations with the
United States, Japan, and China;
Whereas the Government of the Philippines has stressed that China's declared ADIZ seeks to
transfer an entire air zone into Chinese domestic airspace, infringes on freedom of flight in
international airspace, and compromises the safety of civil aviation and the national security
of affected states, and has called on China to ensure that its actions do not jeopardize
regional security and stability;

opposition to any coercive or unilateral actions to change the status quo in the East China

on Defense and Foreign Affairs on February 18, 2014, stated, `We have firmly told China we
will not accept a similar [Air Defense Identification] Zone if it is adopted in the South China
Sea. And the signal we have received thus far is, China does not plan to adopt a similar Zone
in the South China Sea.';
Whereas over half the world's merchant tonnage flows through the South China Sea, and
over 15,000,000 barrels of oil per day transit the Strait of Malacca, fueling economic growth
and prosperity throughout the Asia-Pacific region;
Whereas the increasing frequency and assertiveness of patrols and competing regulations
over disputed territory and maritime areas and airspace in the South China Sea and the East
China Sea are raising tensions and increasing the risk of confrontation;
Whereas the Association of Southeast Asian Nations (ASEAN) has promoted multilateral
talks on disputed areas without settling the issue of sovereignty, and in 2002 joined with
China in signing a Declaration on the Conduct of Parties in the South China Sea that
committed all parties to those territorial disputes to `reaffirm their respect for and
commitment to the freedom of navigation in and over flight above the South China Sea as

their territorial and jurisdictional disputes by peaceful means, without resorting to the threat
or use of force';
Whereas ASEAN and China committed in 2002 to develop an effective Code of Conduct
when they adopted the Declaration on the Conduct of Parties in the South China Sea, yet
negotiations are irregular and little progress has been made;
Whereas, in recent years, there have been numerous dangerous and destabilizing incidents in
waters near the coasts of the Philippines, China, Malaysia, and Vietnam;
Whereas the United States Government is deeply concerned about unilateral actions by any
claimant seeking to change the status quo through the use of coercion, intimidation, or
military force, including the continued restrictions on access to Scarborough Reef and
pressure on long-standing Philippine presence at the Second Thomas Shoal by the People's
Republic of China; actions by any state to prevent any other state from exercising its
sovereign rights to the resources of the exclusive economic zone (EEZ) and continental shelf
by making claims to those areas that have no support in international law; declarations of
administrative and military districts in contested areas in the South China Sea; and the
imposition of new fishing regulations covering disputed areas, which have raised tensions in
the region;
Whereas international law is important to safeguard the rights and freedoms of all states in
the Asia-Pacific region, and the lack of clarity in accordance with international law by
claimants with regard to their South China Sea claims can create uncertainty, insecurity, and
instability;
Whereas the United States Government opposes the use of intimidation, coercion, or force to
assert a territorial claim in the South China Sea;
Whereas claims in the South China Sea must accord with international law, and those that
are not derived from land features are fundamentally flawed;
Whereas ASEAN issued Six-Point Principles on the South China Sea on July 20, 2012,
whereby ASEAN's Foreign Ministers reiterated and reaffirmed `the commitment of ASEAN
Member States to: . . . 1. the full implementation of the Declaration on the Conduct of Parties

Whereas there has been an unprecedented increase in dangerous activities by Chinese
maritime agencies in areas near the Senkaku islands, including between 6 and 25 ships of the
Government of China intruding into the Japanese territorial sea each month since September
2012, between 26 and 124 ships entering the `contiguous zone' in the same time period, and
9 ships intruding into the territorial sea and 33 ships entering in the contiguous zone in
February 2014;
Whereas, although the United States Government does not take a position on the ultimate
sovereignty of the Senkaku Islands, the United States Government acknowledges that they
are under the administration of Japan and opposes any unilateral actions that would seek to
undermine such administration;
Whereas the United States Senate has previously affirmed that the unilateral actions of a
third party will not affect the United States acknowledgment of the administration of Japan
over the Senkaku Islands;
Whereas the United States remains committed under the Treaty of Mutual Cooperation and
Security to respond to any armed attack in the territories under the administration of Japan,

waters in the South China Sea when a People's Liberation Army Navy vessel reportedly
crossed its bow at a distance of less than 500 yards and stopped in the water, forcing the USS
Cowpens to take evasive action to avoid a collision;
Whereas the reported actions taken by the People's Liberation Army Navy vessel in the USS
Cowpens' incident, as publicly reported, appear contrary to the international legal obligations
of the People's Republic of China under COLREGs;
Whereas, on May 1, 2014, the People's Republic of China's state-owned energy company,
CNOOC, placed its deepwater semi-submersible drilling rig Hai Yang Shi You 981 (HD-
981), accompanied by over 25 Chinese ships, in Block 143, 120 nautical miles off Vietnam's
coastline;
Whereas, from May 1 to May 9, 2014, the number of Chinese vessels escorting HD-981
increased to more than 80, including seven military ships, which aggressively patrolled and
intimidated Vietnamese Coast Guard ships in violation of COLREGS, reportedly
intentionally rammed multiple Vietnamese vessels, and used helicopters and water cannons
to obstruct others;
Whereas, on May 5, 2014, vessels from the Maritime Safety Administration of China
(MSAC) established an exclusion zone with a radius of three nautical miles around HD-981,
which undermines maritime safety in the area and is in violation of universally recognized
principles of International Law, including the 1982 United Nations Convention on the Law
of the Sea (UNCLOS);
Whereas China's territorial claims and associated maritime actions in support of the drilling
activity that HD-981 commenced on May 1, 2014, have not been clarified under international
law, including as defined by the 1982 United Nations Convention on the Law of the Sea,

and Vietnam, whose countries all border the Pacific Ocean region, provides a forum where
leaders of regional navies can meet to discuss cooperative initiatives, discuss regional and
global maritime issues, and undertake exercises to strengthen norms and practices that
contribute to operational safety, including protocols for unexpected encounters at sea,
common ways of communication, common ways of operating, and common ways of
engagement;
Whereas, Japan and the People's Republic of China sought to negotiate a Maritime
Communications Mechanism between the defense authorities and a Maritime Search and
Rescue Agreement and agreed in principle to these agreements to address operational safety
on the maritime domains but failed to sign them;
Whereas the Changi Command and Control Center in Singapore provides a platform for all
the countries of the Western Pacific to share information on what kind of contact at sea and

almost all political and diplomatic avenues for a peaceful negotiated settlement of its

assert disputed maritime or territorial claims or alter the status quo;
(2) strongly urges that all parties to maritime and territorial disputes in the region exercise

China said on Thursday [August 1] it had lodged a formal complaint with the United States
after the U.S. Senate passed a resolution expressing concern about Chinese actions in the
disputed East and South China Seas....
“The above resolution proposed by a minority of senators took heed of neither history nor
facts, unjustifiably blaming China and sending the wrong message,” China’s Foreign
Ministry said in a statement.
“China expresses its strong opposition, and has already made stern representations with the
U.S. side. We urge the relevant senators to respect the facts and correct their mistakes in

Appendix C. February 5, 2014, Testimony of
Assistant Secretary of State Daniel Russel

The appendix presents the text of the written statement of Assistant Secretary of State Daniel
Russel for a February 5, 2014, hearing before the subcommittee on Asia and the Pacific of the
House Foreign Affairs Committee on maritime disputes in East Asia. The text of the statement is
as follows:
Chairman Chabot, Members of the Subcommittee, thank you for the opportunity to testify
today on these important issues.
Before I begin, I would also like to take this opportunity to thank you, Chairman Chabot, for
your leadership on this issue and for your work to enhance our engagement with the Asia-
Pacific region. This Subcommittee has contributed to the rich bipartisan tradition of
engaging the Asia-Pacific and advancing U.S. interests there.
The Members of this Subcommittee know well the importance of the Asia-Pacific region to
American interests. The broader region boasts over half the world’s population, half of the
world’s GDP, and nearly half of the world’s trade, and is home to some of the fastest
growing economies in the world. More and more American citizens are now living, working,
and studying in this part of the world and people-to-people and family ties between
Americans and the peoples of the Asia-Pacific have witnessed tremendous growth. Growing
numbers of American companies are investing in and exporting their products and services
to rapidly expanding East Asian markets. Asia-Pacific businesses are increasing their profiles
in the United States and creating jobs for American workers. And, as the region’s economies
continue to grow and their interests expand, it becomes increasingly important that the
governments and institutions there contribute to upholding and strengthening international
law and standards – ranging from human rights to environmental protection to responsible
policies on climate change, maritime security, and trade and investment. The effects of what
happens in the Asia-Pacific Region will be felt across the globe and have direct implications
for America’s interests.
It is precisely with this in mind that this administration has for the past five years made
sustained engagement in the Asia-Pacific a strategic priority. This is precisely why Secretary
Kerry is about to make his fifth visit to Asia in ten months and why he has devoted so much
time and effort to meeting, calling and consulting with his Asian counterparts.
We have a strong stake in the continuing economic growth of this region, and we are
working to ensure that Americans can fully participate in that growth and share in that
prosperity. We are negotiating high-standard trade and investment agreements that will
unlock the dynamism of Pacific Rim economies for mutual benefit. We are bolstering
regional cooperation on transnational issues through ASEAN and its related institutions. And
we are helping countries manage complex environmental issues resulting from rapid
development. The common thread running through our strategic rebalancing is a
determination to ensure that the Asia-Pacific remains an open, inclusive, and prosperous
region guided by widely accepted rules and standards and a respect for international law.
Since the end of the Second World War, a maritime regime based on international law that
promotes freedom of navigation and lawful uses of the sea has facilitated Asia’s impressive
economic growth. The United States, through our our alliances, our security partnerships and
our overall military presence and posture, has been instrumental in sustaining that maritime
regime and providing the security that has enabled the countries in the region to prosper. As
Congressional Research Service

a maritime nation with global trading networks, the United States has a national interest in
freedom of the seas and in unimpeded lawful commerce. From President Thomas Jefferson’s
actions against the Barbary pirates to President Reagan’s decision that the United States will
abide by the Law of the Sea Convention’s provisions on navigation and other traditional uses
of the ocean, American foreign policy has long defended the freedom of the seas. And as we
consistently state, we have a national interest in the maintenance of peace and stability;
respect for international law; unimpeded lawful commerce; and freedom of navigation and
overflight in the East China and South China Seas.
For all these reasons, the tensions arising from maritime and territorial disputes in the Asia-
Pacific are of deep concern to us and to our allies. Both the South China and East China Seas
are vital thoroughfares for global commerce and energy. Well over half the world’s merchant
tonnage flows through the South China Sea, and over 15 million barrels of oil per day
transited the Strait of Malacca last year, with most of it continuing onward through the East
China Sea to three of the world’s largest economies—Japan, the Republic of Korea, and
China. A simple miscalculation or incident could touch off an escalatory cycle.
Confrontations between fishermen and even law enforcement patrols are not unusual in these
waters. But the frequency and assertiveness of some countries’ patrols are increasing. In
addition, the imposition of competing regulations by different countries over disputed
territory and associated maritime areas and airspace is raising tensions and increasing the risk
of confrontation. We witnessed a tragic incident in May of last year, when a Philippine Coast
Guard patrol shot and killed a fisherman from Taiwan. Both sides, to their credit, took steps
to prevent an escalation of tensions. But the risk of confrontation could have very serious
adverse consequences for all of our economic and security interests.
Accordingly, we have consistently emphasized in our diplomacy in the region as well as in
our public messaging the importance of exercising restraint, maintaining open channels of
dialogue, lowering rhetoric, behaving safely and responsibly in the sky and at sea, and
peacefully resolving territorial and maritime disputes in accordance with international law.
We are working to help put in place diplomatic and other structures to lower tensions and
manage these disputes peacefully. We have sought to prevent provocative or unilateral
actions that disrupt the status quo or jeopardize peace and security. When such actions have
occurred, we have spoken out clearly and, where appropriate, taken action. In an effort to
build consensus and capabilities in support of these principles, the administration has
invested considerably in the development of regional institutions and bodies such as the
ASEAN Regional Forum, the ASEAN Defense Ministers Meeting Plus, the East Asia
Summit, and the Expanded ASEAN Maritime Forum. These forums, as they continue to
develop, play an important role in reinforcing international law and practice and building
practical cooperation among member states.
In the South China Sea, we continue to support efforts by ASEAN and China to develop an
effective Code of Conduct. Agreement on a Code of Conduct is long overdue and the
negotiating process should be accelerated. This is something that China and ASEAN
committed to back in 2002 when they adopted their Declaration on the Conduct of Parties in
the South China Sea. An effective Code of Conduct would promote a rules-based framework
for managing and regulating the behavior of the relevant countries in the South China Sea. A
key part of that framework, which we and many others believe should be adopted quickly, is
inclusion of mechanisms such as hotlines and emergency procedures for preventing incidents
in sensitive areas and managing them when they do occur in ways that prevent disputes from
escalating.
And in the East China Sea, we remain concerned about the serious downturn in China-Japan
relations. We support Japan’s call for diplomacy and crisis management procedures in order
to avoid a miscalculation or a dangerous incident. It is important to lower tensions, turn
down the rhetoric, and exercise caution and restraint in this sensitive area. China and Japan

are the world’s second and third largest economies and have a shared interest in a stable
environment to facilitate economic growth. Neither these two important countries nor the
global economy can afford an unintended clash that neither side seeks or wants. It is
imperative that Japan and China use diplomatic means to manage this issue peacefully and
set aside matters that can’t be resolved at this time.
China’s announcement of an Air Defense Identification Zone (ADIZ) over the East China
Sea in November was a provocative act and a serious step in the wrong direction. The
Senkakus are under the administration of Japan and unilateral attempts to change the status
quo raise tensions and do nothing under international law to strengthen territorial claims. The
United States neither recognizes nor accepts China’s declared East China Sea ADIZ and has
no intention of changing how we conduct operations in the region. China should not attempt
to implement the ADIZ and should refrain from taking similar actions elsewhere in the
region.
Mr. Chairman, we have a deep and long-standing stake in the maintenance of prosperity and
stability in the Asia-Pacific and an equally deep and abiding long-term interest in the
continuance of freedom of the seas based on the rule of law—one that guarantees, among
other things, freedom of navigation and overflight and other internationally lawful uses of
the sea related to those freedoms. International law makes clear the legal basis on which
states can legitimately assert their rights in the maritime domain or exploit marine resources.
By promoting order in the seas, international law is instrumental in safeguarding the rights
and freedoms of all countries regardless of size or military strength.
I think it is imperative that we be clear about what we mean when the United States says that
we take no position on competing claims to sovereignty over disputed land features in the
East China and South China Seas. First of all, we do take a strong position with regard to
behavior in connection with any claims: we firmly oppose the use of intimidation, coercion
or force to assert a territorial claim. Second, we do take a strong position that maritime
claims must accord with customary international law. This means that all maritime claims
must be derived from land features and otherwise comport with the international law of the
sea. So while we are not siding with one claimant against another, we certainly believe that
claims in the South China Sea that are not derived from land features are fundamentally
flawed. In support of these principles and in keeping with the longstanding U.S. Freedom of
Navigation Program, the United States continues to oppose claims that impinge on the rights,
freedoms, and lawful uses of the sea that belong to all nations.
As I just noted, we care deeply about the way countries behave in asserting their claims or
managing their disputes. We seek to ensure that territorial and maritime disputes are dealt
with peacefully, diplomatically and in accordance with international law. Of course this
means making sure that shots aren’t fired; but more broadly it means ensuring that these
disputes are managed without intimidation, coercion, or force. We have repeatedly made
clear that freedom of navigation is reflected in international law, not something to be granted
by big states to others. President Obama and Secretary Kerry have made these points
forcefully and clearly in their interactions with regional leaders, and I—along with my
colleagues in the State Department, Defense Department, the National Security Council and
other agencies—have done likewise.
We are also candid with all the claimants when we have concerns regarding their claims or
the ways that they pursue them. Deputy Secretary Burns and I were in Beijing earlier this
month to hold regular consultations with the Chinese government on Asia-Pacific issues, and
we held extensive discussions regarding our concerns. These include continued restrictions
on access to Scarborough Reef; pressure on the long-standing Philippine presence at the
Second Thomas Shoal; putting hydrocarbon blocks up for bid in an area close to another
country’s mainland and far away even from the islands that China is claiming; announcing

administrative and even military districts in contested areas in the South China Sea; an
unprecedented spike in risky activity by China’s maritime agencies near the Senkaku Islands;
the sudden, uncoordinated and unilateral imposition of regulations over contested airspace in
the case of the East China Sea Air Defense Identification Zone; and the recent updating of
fishing regulations covering disputed areas in the South China Sea. These actions have raised
tensions in the region and concerns about China’s objectives in both the South China and the
East China Seas.
There is a growing concern that this pattern of behavior in the South China Sea reflects an
incremental effort by China to assert control over the area contained in the so-called “nine-
dash line,” despite the objections of its neighbors and despite the lack of any explanation or
apparent basis under international law regarding the scope of the claim itself. China’s lack of
clarity with regard to its South China Sea claims has created uncertainty, insecurity and
instability in the region. It limits the prospect for achieving a mutually agreeable resolution
or equitable joint development arrangements among the claimants. I want to reinforce the
point that under international law, maritime claims in the South China Sea must be derived
from land features. Any use of the “nine dash line” by China to claim maritime rights not
based on claimed land features would be inconsistent with international law. The
international community would welcome China to clarify or adjust its nine-dash line claim to
bring it in accordance with the international law of the sea.
We support serious and sustained diplomacy between the claimants to address overlapping
claims in a peaceful, non-coercive way. This can and should include bilateral as well as
multilateral diplomatic dialogue among the claimants. But at the same time we fully support
the right of claimants to exercise rights they may have to avail themselves of peaceful
dispute settlement mechanisms. The Philippines chose to exercise such a right last year with
the filing of an arbitration case under the Law of the Sea Convention.
Both legal and diplomatic processes will take time to play out. The effort to reach agreement
on a China-ASEAN Code of Conduct has been painfully slow. However, there are important
steps that the relevant parties can take in the short term to lower tensions and avoid
escalation. One line of effort, as I mentioned earlier, is to put in place practical mechanisms
to prevent incidents or manage them when they occur. Another common-sense measure
would be for the claimants to agree not to undertake new unilateral attempts to change the
status quo, defined as of the date of the signing of the 2002 Declaration of Conduct, that
would include agreement not to assert administrative measures or controls in disputed areas.
And as I have indicated, all claimants—not only China—should clarify their claims in terms
of international law, including the law of the sea.
In the meantime, a strong diplomatic and military presence by the United States, including
by strengthening and modernizing our alliances and continuing to build robust strategic
partnerships, remains essential to maintain regional stability. This includes our efforts to
promote best practices and good cooperation on all aspects of maritime security and bolster
maritime domain awareness and our capacity building programs in Southeast Asia. The
Administration has also consistently made clear our desire to build a strong and cooperative
relationship with China to advance peace and prosperity in the Asia-Pacific, just as we
consistently have encouraged all countries in the region to pursue positive relations with
China. And this includes working with all countries in the region to strengthen regional
institutions like ASEAN and the East Asia Summit as venues where countries can engage in
clear dialogue with all involved about principles, values and interests at stake, while
developing cooperative activities – like the Expanded ASEAN Seafarers Training initiative
we recently launched – to build trust and mechanisms to reduce the chances of incidents.

To conclude, this is an issue of immense importance to the United States, the Asia-Pacific,
and the world. And I want to reaffirm here today that the United States will continue to play
a central role in underwriting security and stability in the Asia-Pacific.
Mr. Chairman, I thank you for this opportunity to appear before you today to discuss this
important issue. I look forward to answering any questions you may have.107
