Thailand: Background and U.S. Relations
Overview
Thailand is a long-time military ally and economic partner
of the United States. These ties endure, but more than a
decade of political turmoil in Thailand, including two
military coups in 2006 and 2014, has complicated U.S.Thai relations and erased Thailand’s image as a model
democracy in Southeast Asia.
Thailand conducted nationwide elections in March 2019—
its first since 2011—and in June seated a new government
led by Prime Minister Prayuth Chan-ocha, the former
Commander-in-Chief of the Royal Thai Army who led the
2014 coup. The polls were conducted under new rules
drafted by the junta that structurally protect the military’s
influence, and questions remain about the new
government’s popular legitimacy. The military government
also rewrote Thailand’s constitution to create a militaryappointed Senate, and was widely criticized for harassment
of government critics and severe restrictions on freedom of
expression and assembly.
The United States suspended security assistance to Thailand
after the 2014 coup as required by law, but other aspects of
the U.S.-Thai military relationship remain, including the
annual Cobra Gold military exercise, the largest multilateral
exercise in Asia. The United States continues to provide
non-security aid to the country, and maintains regional
offices for many U.S. programs at the Embassy in Bangkok.
As one of Southeast Asia’s most developed nations,
Thailand has the potential to support U.S. initiatives, such
as broadening regional defense cooperation. Thailand is the
2019 chair of the Association of Southeast Asian Nations
(ASEAN), and as such is to convene and lead the region’s
key multilateral forums this year. However, Bangkok’s
domestic challenges and the resulting damage to U.S.-Thai
relations have diminished opportunities for new bilateral
coordination. Following the 2019 polls, U.S. policymakers
face challenges in rekindling the bilateral relationship while
encouraging Thailand to fully return to democratic norms.
Thailand’s Politics and Elections
Thailand’s political turmoil has involved a broad clash
between the nation’s political establishment (a mix of the
military, royalists, senior bureaucrats, and many urban and
middle class citizens) and backers of former Prime Minister
Thaksin Shinawatra, who was deposed in the 2006 coup
and now resides overseas. Thaksin was popular, particularly
with the rural poor, because of his populist policies and
political empowerment of traditionally marginalized
communities. Yet, Thaskin was, and still is, a divisive
figure, and critics accused him of corruption and human
rights abuses while he was in office. Between 2001 and
2011, Thaksin and his supporters won six consecutive
national elections, but their leaders were repeatedly
removed from office, by either military or judicial coup.
The 2014 military coup deposed an acting prime minister
after Thaksin’s sister, Yingluck Shinawatra, was ousted
from the premiership by a Constitutional Court decision
that many observers saw as politically motivated. During
this period of instability, Thailand has seen numerous largescale demonstrations, and some have turned violent. In
2010, clashes over several weeks killed 80 civilians in
Bangkok.

The 2014 coup was Thailand’s 12th successful coup since
1932. It installed then-Army Commander Prayuth as prime
minister and head of the military junta. Although Prayuth
declared an end to martial law in April 2015, the junta
retained authoritarian powers under the new Constitution
approved by Thai voters in 2016 that was later signed into
law by the King. The new Constitution limits the power of
political parties and gives the military the ability to appoint
members to an upper house that along with the elected
lower house selects the prime minister.
In the March 2019 polls, voting ran smoothly overall. The
Election Commission of Thailand, however, received
widespread criticism when irregularities such as releasing
inconsistent and delayed results occurred, raising
skepticism about the credibility of the elections. Poll
statistics, such as voter turnout in comparison to the number
of ballots cast, fluctuated in the days after the election. As
poll results continued to change, Prayuth’s military-backed
party and the opposing pro-democratic Thaksin faction both
claimed to have won enough votes to form a coalition
government. Official results were released on May 9, and
Prayuth’s party was able to form a coalition government in
Parliament by a narrow margin. Prayuth was officially
voted in as Prime Minister on June 5, 2019.
Royal Succession
The monarchy is one of Thailand’s most powerful political
institutions. It has few formal authorities, but during King
https://crsreports.congress.gov
Thailand: Background and U.S. Relations
Bhumiphol’s reign, the palace enjoyed popular support and,
in turn, political influence. In October 2016, King
Bhumiphol passed away, ending a 70-year reign that had
made him the world’s longest serving monarch. After his
accession to the throne, Bhumiphol’s son Maha
Vajiralongkorn, officially known as King Rama X, has been
more politically active than his father, opposing some parts
of the 2016 Constitution and taking control of the bureau
managing the throne’s vast fortune in July 2017.
Sino-Thai ties could expand to fill the vacuum. In June
2017, the Thai government announced it would buy 34
Chinese armored personnel carriers, perhaps in an attempt
to reduce its reliance on U.S.-made weapons.
U.S.-Thai Trade and Economic Relations
Bhumiphol rarely interfered in politics in his later years, but
was seen as a moderating force that fostered stability
among competing political actors. The new king is much
less popular than his father, and his political inclinations
lean towards the military, which has played a major role in
supporting royal legitimacy. Since the 2014 coup, as the
military government has sought to limit political criticism,
it has interpreted Thailand’s lese-majeste laws, which
forbid insults to the monarch, more broadly, to include
perceived insults to other officials and government entities.
Thailand is an upper middle-income country, and trade and
foreign investment play a large role in its economy. In
2018, Thailand’s GDP grew 3.7%, continuing a period of
comparatively slow growth. The United States is Thailand’s
third largest trading partner, behind Japan and China. In
2018, Thailand was the United States’ 20th largest goods
trading partner; its 26th largest goods export market; and a
source of $44.5 billion in total two-way goods trade. In
2018, the United States ran a $19.31 billion trade deficit
with Thailand, ranking Thailand as the country with the 13th
largest bilateral surplus with the United States. In 2017,
USTR placed Thailand on its Section 301 Priority Watch
List because of the country’s poor intellectual property
rights protection and enforcement.
U.S.-Thailand Security Relations
Thailand’s Regional Relations
Security cooperation has long been the strongest pillar of
the U.S.-Thai relationship. In addition to hosting military
exercises, Thailand has provided the U.S. military with
access to important facilities, particularly the strategically
located Utapao airbase. The U.S. military used Utapao for
refueling operations during its campaigns in Iraq and
Afghanistan in the 2000s, as well as for multinational relief
efforts, including after the 2004 Indian Ocean tsunami and
2015 Nepal earthquake. For U.S. officials, intelligence and
law enforcement cooperation with Thai counterparts
remains a priority, particularly as the United States
confronts international criminal and drug networks. In the
past, transnational terrorist organizations have taken
advantage of Thailand’s relatively permissive environment,
including tourist-friendly travel procedures and central
location, for their operations in the region.
Before the most recent coup, U.S. military leaders generally
touted the alliance as apolitical and praised the Thai armed
forces for exhibiting restraint amidst the competing protests
and political turmoil. However, following the 2014 coup,
the United States immediately suspended military aid to
Thailand, including $3.5 million in Foreign Military
Financing (FMF) and $85,000 in International Military
Education and Training (IMET) funds. The U.S. took
similar action following the 2006 military coup.
The United States has not suspended non-military aid, and
capacity building assistance to the country largely has
continued. In February 2018, USAID committed $10
million to curtail human trafficking in Thailand. Some
military exercises, including the annual Cobra Gold military
exercises, have continued. In the years immediately after
the coup, fewer U.S. troops participated in Cobra Gold than
in previous years, but the scale of U.S. participation has
since returned to pre-coup levels.
Several analysts have noted that limits on U.S. engagement
could lead U.S.-Thai security ties could weaken, and that
Thailand’s importance for U.S. interests in Southeast Asia
stems from its large economy, its good relations with its
neighbors, and, until the coups, its relatively long-standing
democratic rule. Thailand is chair of ASEAN for 2019, and
Thai officials hope to foster an ASEAN position on the Free
and Open Indo-Pacific, a strategic concept adopted by the
Trump Administration. However, because of Thailand’s
political turmoil, it has recently played little leadership role
in the region. Historically, Sino-Thai ties have been close.
Unlike several of its Southeast Asian neighbors, Thailand
has no territorial disputes with China in the South China
Sea. Thai imports from China have boomed under the 2010
China-ASEAN Free Trade Agreement.
Human Rights and Democracy Concerns
International groups, some Members of Congress, and U.S.
officials have criticized Thailand’s alleged human rights
abuses, including arbitrary arrests and the lack of
protections for trafficking victims, laborers, and refugees.
International groups have also identified human rights
violations in the Muslim-majority southern provinces where
an ongoing insurgency has killed over 7,000 people since
2004. In its 2018 Trafficking in Persons report, the State
Department ranked Thailand as a Tier 2 country, an
improvement over recent years. Thailand argues that human
smuggling, not trafficking, is the main cross-border issue.
Thailand is not a signatory to the 1951 Refugee Convention
nor its 1967 Protocol and does not have a formal national
asylum framework. In 2016, the United Nations High
Commissioner for Refugees reported that Thailand hosted
nearly 600,000 refugees, asylum-seekers, and stateless
have complicated U.S.Thai relations. The Thai government’s efforts to manipulate
political processes and suppress critics has raised questions
about Thailand’s prospects for returning to full democratic
governance including the peaceful transfer of power and
protection for civil liberties, and eventually recognizing
civilian authority over the military. After holding elections
in early 2019 that many regarded as flawed, Thailand has
indicated it wants to reset its relationship with the United
States after five years of coup-triggered constraints.
As one of Southeast Asia’s most developed nations and a
long-time U.S. partner on a range of issues, Thailand has
the potential to support U.S. initiatives, such as broadening
regional defense cooperation. Thailand is the 2019 chair of
the Association of Southeast Asian Nations (ASEAN), and
is to convene and lead the region’s key multilateral forums
this year. However, U.S. policymakers face challenges in
rekindling the bilateral relationship with Thailand, which
was frustrated by U.S. criticism of the coup, while also
encouraging it to fully return to democratic norms.
Background on Thailand’s Political Landscape
As demonstrated in the close election outcome, Thailand
remains deeply politically divided, with the potential for
more conflicts ahead. Thailand’s political turmoil has
involved a broad clash between the nation’s political
establishment (a mix of the military, royalists who are
staunch supporters of the monarchy, senior bureaucrats, and
many urban and middle class citizens) and democracy
activists and backers of former Prime Minister Thaksin
Shinawatra, who was deposed in the 2006 coup and now
resides overseas. Thaksin was popular, particularly with the
rural poor, because of his populist policies, challenges to
the traditional elites, and political empowerment of
traditionally marginalized communities.
Between 2001 and 2011, Thaksin and his supporters won
six consecutive national elections, but their leaders were
repeatedly removed from office, by either military or
judicial coup. During this period of instability, Thailand
saw numerous large-scale demonstrations, several of which
resulted in violent confrontations between factions, or with
the military and police. In 2010, clashes between the
military and pro-Thaksin demonstrators over several weeks
killed 80 civilians in Bangkok.
March 2019 Elections
Thailand
Thailand conducted nationwide elections in March 2019—
its first since 2011—and in June seated a new government
led by Prime Minister Prayuth Chan-ocha, the former
Commander-in-Chief of the Royal Thai Army who led the
2014 coup. The polls were conducted under new rules
drafted by the junta that provided structural advantages for
military-backed parties, raising questions about the new
government’s popular legitimacy. Voting overall ran
smoothly, but the Election Commission of Thailand was
widely criticized for releasing inconsistent and delayed
results, raising skepticism about the credibility of the
tallying process. Official results showed that the main
opposition party had won the highest number of elected
seats. Prayuth’s party, however, was able to form a
coalition government with the full support of the militaryappointed Senate.
The 2014 coup was Thailand’s 12th successful coup since
1932. The junta drafted a new constitution that created a
military-appointed Senate and limited the power of political
parties.
On July 19, 2019, the U.S. State Department notified
Congress of its certification that a democratically elected
government had taken office in Thailand. (Under the
Foreign Assistance Act of 1961 [P.L. 87-195; 22 U.S.C.
2151 et seq.], certain categories of military assistance may
not be used to “finance directly any assistance to any
country whose duly elected head of government is deposed
by military coup or decree.”) With this certification, the
United States can resume the provision of military
assistance that was suspended after the 2014 coup, which
includes Foreign Military Sales (FMS) and International
Military Education Training (IMET).
The monarchy is one of Thailand’s most powerful political
institutions. The former king, Bhumibol Adulyadej, passed
away in 2016, ending a 70-year reign that had made him the
world’s longest serving monarch. The palace has few
formal authorities, but Bhumibol enjoyed tremendous
popular support and, in turn, political influence. After his
accession to the throne, Bhumiphol’s son Maha
Vajiralongkorn, now officially known as King Rama X, has
been more politically active than his father was in his last
years, opposing some parts of the 2016 Constitution and
taking control of the bureau managing the throne’s vast
fortune in July 2017.

Thailand: Background and U.S. Relations
U.S.-Thailand Relations
The United States and Thailand have longstanding bilateral
relations, including a treaty alliance that derives from the
1954 Southeast Asian Treaty Organization, which the U.S.
and Thailand reinforced in a bilateral 1962 agreement, the
Thanat-Rusk Communique. The United States operates
numerous regional offices from the Bangkok Embassy, one
of the largest diplomatic missions in the world. Bilateral
cooperation includes security initiatives and operations,
regional health and education, and others.
Security Relations
Security cooperation, which dates back to cooperation in
the Korean and Vietnam Wars, has long been the highest
profile pillar of the U.S.-Thai relationship. In addition to
hosting military exercises, Thailand has provided the U.S.
military with access to important facilities, particularly the
strategically located Utapao airbase and Sattahip naval
base. The U.S. military used Utapao for refueling
operations during its campaigns in Iraq and Afghanistan in
the 2000s, as well as for multinational relief efforts,
including after the 2004 Indian Ocean tsunami and 2015
Nepal earthquake. For U.S. officials, intelligence and law
enforcement cooperation with Thai counterparts remains a
priority, particularly as the United States confronts
international criminal and drug networks.
Before the 2014 coup, U.S. military leaders touted the
alliance as apolitical and praised the Thai armed forces for
exhibiting restraint amidst the competing protests and
political turmoil. Following the coup, the United States
suspended military aid to Thailand as required by law,
including $3.5 million in FMF and $85,000 in IMET funds.
The United States did not suspended non-military aid or
cooperation, and capacity building assistance to the country
was largely uninterrupted. The large-scale annual Cobra
Gold military exercises continued.
Several analysts have suggested that limits on U.S.
engagement allowed U.S.-Thai security ties to weaken, and
that Sino-Thai ties—which already were strong and
growing—expanded to fill the vacuum. China’s stateowned arms industries provided an appealing and lessexpensive alternative for Thailand, particularly in light of
U.S. restrictions on arms sales following the 2014 coup. In
2015, Thailand acquired three diesel-electric submarines
from China, Thailand’s most expensive defense
procurement to date. In 2017, the Thai government
announced it would buy 34 Chinese armored personnel
carriers, perhaps in an attempt to reduce its reliance on
U.S.-made weapons, and also purchased a $530 million
submarine from China.
Trade and Economic Relations
Thailand is an upper middle-income country, and trade and
foreign investment play a large role in its economy. In
2018, Thailand’s GDP grew 3.7%, continuing a period of
slow growth compared to previous years. The United States
is Thailand’s third largest trading partner, behind Japan and
China. In 2018, Thailand was the United States’ 20 th largest
goods trading partner; its 26th largest goods export market;
and a source of $44.5 billion in total two-way goods trade.
In 2018, the United States ran a $19.31 billion trade deficit
with Thailand, ranking Thailand as the country with the 13 th
largest bilateral surplus with the United States.
Thailand did not join negotiations for the proposed regional
Trans-Pacific Partnership (TPP) agreement, and trade
discussions between the United States have focused more
recently on Thailand’s poor intellectual property rights
protections and its protection and subsidization of its large
agriculture industry. Thailand has remained on the USTR’s
Section 301 Watch List since 2018.
Thailand’s Regional Relations
Thailand’s importance for U.S. interests in Southeast Asia
stems from its large economy and its good relations with its
neighbors. Thailand is chair of ASEAN for 2019, and
Thailand helped broker consensus on an ASEAN position
on the Free and Open Indo-Pacific, a strategic concept
adopted by the Trump Administration. Thailand has
extensive trade and investment relations across the region.
Japan is its largest source of foreign direct investment and
its second largest trading partner, after China.
Historically, Sino-Thai ties have been close, and trade has
burgeoned under the 2010 China-ASEAN Free Trade
Agreement. Unlike several of its Southeast Asian
neighbors, Thailand has no territorial disputes with China in
the South China Sea and has been generally loathe to take
an assertive stance against China’s actions there. As a
member of the China-led Belt and Road Initiative (BRI),
Thailand is involved in a high speed railway project that
would connect southern China with several Southeast Asian
nations to its south. The project, which has been backed by
the Prayuth government, has raised concerns in Thailand by
some who question whether it can be operated profitably.
Human Rights and Democracy Concerns
International organizations have criticized Thailand’s
alleged human rights abuses, including the military
government’s curtailment of freedoms of speech and
assembly; harassment of government critics; use of lese
majeste laws to muzzle dissent; arbitrary arrests; and the
lack of protections for human trafficking victims, laborers,
and refugees. International groups have also identified
human rights violations in the Muslim-majority southern
provinces where an ongoing insurgency has killed over
7,000 people since 2004.
In its 2018 Trafficking in Persons report, the State
Department ranked Thailand as a Tier 2 country, an
improvement over recent years. Thailand argues that human
smuggling, not trafficking, is the main cross-border issue.
Thailand is not a signatory to the 1951 Refugee Convention
nor its 1967 Protocol and does not have a formal national
asylum framework. In 2019, the United Nations High
Commissioner for Refugees reported that Thailand hosted
over 95,000 refugees and stateless people.
