Mexico: Background and U.S. Relations

Summary
Congress has maintained significant interest in neighboring Mexico, a close ally and top trade
partner whose political and economic situation has significant ramifications for the United States.
On December 1, 2012, the Institutional Revolutionary Party (PRI) retook the Mexican presidency
after 12 years in the opposition. Analysts are divided on how differently PRI President Enrique
Peña Nieto will govern than his PRI predecessors who ruled Mexico from 1929 to 2000.
Supporters maintain that Peña Nieto heads a “new PRI” government that is free from corruption
and is enacting reforms that proved elusive for his two National Action Party (PAN) predecessors.
Skeptics question the government’s commitment to transparency and human rights and whether
the reforms that have been enacted will be implemented effectively.
President Peña Nieto’s first year in office has brought mixed results for Mexico. The economy
faltered (GDP growth fell from 3.7% in 2012 to 1.2% in 2013) and violent crime remained
elevated. Nevertheless, Peña Nieto’s “Pact for Mexico” agreement with the conservative PAN and
leftist Party of the Democratic Revolution (PRD) facilitated the passage of significant financial,
education, telecommunications, and fiscal reforms. Although the PRD recently withdrew from the
Pact, Peña Nieto ended the year on a high note, signing historic constitutional reforms to open
Mexico’s energy sector to private investment on December 20, 2013.
U.S. Policy
As Mexico has experienced a domestic shift in power, U.S.-Mexican relations have also evolved.
President Obama and Vice President Biden embraced President Peña Nieto’s desire to bolster
economic ties and focus on issues beyond security, including education, during their respective
May and September 2013 visits to Mexico. Presidents Obama and Peña Nieto are to meet again in
Mexico on February 19, 2014 for a North American Leaders’ Summit with Canadian Prime
Minister Stephen Harper. U.S.-Mexican security cooperation has continued under the Mérida
Initiative framework, but friction has occurred due to limits put on U.S. involvement in some law
enforcement and intelligence operations and revelations of alleged U.S. spying on former
President Calderón and President-elect Peña Nieto. U.S. approval of the Trans-Boundary
Hydrocarbons Agreement signed in February 2012 on managing oil resources in the Gulf of
Mexico and Mexico’s energy reforms could create opportunities for energy cooperation.
Legislative Action
This year, a broad range of issues in U.S.-Mexican relations have received congressional
attention. The Senate passed S. 744 in June 2013, a comprehensive immigration reform bill that
includes additional funding for border security; the House has passed a series of discrete
immigration measures, including H.R. 1417, which would require new border security metrics. In
December 2013, Congress approved the U.S.-Mexico Transboundary Hydrocarbons Agreement
that is intended to facilitate joint development of oil and natural gas in part of the Gulf of Mexico
(P.L. 113-67). Congress has continued oversight of the Mérida Initiative and included at least
$200 million in assistance to Mexico, subject to human rights conditions, in the FY2014
Consolidated Appropriations Act, P.L. 113-76, along with funding for additional customs
inspectors and infrastructure at the border. P.L. 113-76 also requires a State Department report on
how it is addressing a U.S.-Mexico water dispute in the Rio Grande Basin. The House-passed
version of the 2013 farm bill, H.R. 2642, also addresses that issue.

U.S.-Mexican energy cooperation and the recent reforms that Mexico has enacted have generated
congressional interest, as has how Mexico’s participation in the Trans Pacific Partnership (TPP)
negotiations may impact U.S.-Mexico economic relations, especially in the context of the 20th
anniversary of the North American Free Trade Agreement (NAFTA).
Mexico’s participation in the Trans Pacific Partnership (TPP) negotiations and the 20th

Mexico: Background and U.S. Relations

Introduction
Congress has maintained a strong interest in Mexico, a top trade partner and energy supplier, with
which the United States shares a nearly 2,000 mile border and strong cultural and historical ties.
Economically, the United States and Mexico are heavily interdependent, and the U.S. economy
could benefit if Mexico is able to boost its growth rates by successfully implementing the historic
reforms enacted in 2013. Similarly, security conditions in Mexico affect U.S. national security,
particularly along the U.S.-Mexico border. Congress may closely monitor whether the reduction
in organized-crime related violence that Mexico has experienced since 2012 can be sustained
without jeopardizing bilateral efforts against transnational organized crime. Maintaining strong
bilateral cooperation on these and other issues, while also ensuring that U.S. interests are
protected, are likely to be of interest during the second session of the 113th Congress.
This report provides an overview of political and economic conditions in Mexico followed by
assessments of some key issues of congressional interest in Mexico: migration, trade, security,
human rights, energy, and water issues. The report summarizes legislative action that has
occurred related to these topics and refers to other CRS products and experts that can be
consulted for further information. It will be updated to address major developments in Mexico
and in Mexican-U.S. relations that are of interest to Congress.
Political Situation
Over the past two decades, Mexico has transitioned from a centralized political system dominated
by the Institutional Revolutionary Party (PRI) to a true multiparty democracy. Since the PRI last
governed in the 1990s, presidential power has become increasingly constrained by Mexico’s
Congress, Supreme Court, and increasingly powerful governors.1 Partially as a result of those
constraints, two successive National Action Party (PAN) administrations struggled to enact the
structural reforms needed to boost Mexico’s economic competitiveness and effectively address
the country’s security challenges.
The PAN government of Felipe Calderón (2006-2012) pursued an aggressive anticrime strategy
and increased security cooperation with the United States. Those efforts helped Mexico arrest or
kill record numbers of drug kingpins, but some 60,000 people may have died as a result of
organized crime-related violence during the Calderón Administration. Mexico’s security
challenges overshadowed some of the Calderón government’s achievements, including its
economic stewardship during and after the global financial crisis and expansion of access to
health care.2

July 1, 2012, Elections: Return of PRI Dominance3
The July 1, 2012, elections occurred at a time when Mexico was experiencing modest economic
growth after a severe economic crisis (in 2009) and a growing security crisis under two
successive PAN administrations. As a result, economic and security issues figured as top concerns
among the Mexican electorate. Voters appeared to believe that the PRI would be best equipped to

restore order and hasten economic growth, despite uncertainty about how the party’s return might
impact Mexican democracy given its past reputation for corruption and undemocratic practices.4
Twelve years after losing the presidency for the first time in 71 years, the PRI won the
presidential election, a plurality of seats in the Senate and Chamber of Deputies, and three of six
gubernatorial elections held on July 1, 2012. Despite those victories, PRI/Green Ecological Party
(PVEM) candidate Enrique Peña Nieto won by a relatively narrow margin (6.6% of the vote) over
Andrés Manuel López Obrador of the leftist Party of the Democratic Revolution (PRD) and the
PRI/PVEM failed to capture a majority in either legislative chamber (see Figure 2 below).
However, unlike his predecessor, President Enrique Peña Nieto took office with his party
controlling 20 of 32 governorships.

Pena Nieto’s Administration
Structural Changes
Mexico’s presidential transitions are characterized not only by a high level of turnover in
government agencies, but often by a complete overhaul of governmental structures and
organizational patterns. For example, President Peña Nieto has returned much of the power to the
Interior Ministry that it had before the PAN took office. With congressional approval, he placed
the Secretariat of Public Security (SSP, including the Federal Police5) and intelligence functions
under the authority of the Interior Ministry. That ministry, rather than the SSP, now coordinates

5 Recent Mexican presidents have also sought to create new or revamped federal police entities. The Peña Nieto
government is reforming, rather than dismantling, the Federal Police that were recruited, trained, and equipped by
former President Calderón with significant U.S. assistance.

security efforts with the military and state and municipal authorities. The Interior Ministry is also
creating a new militarized police entity within the Federal Police, the National Gendarmerie.6
The Attorney General’s Office (PGR) is being revamped and modernized, potentially to serve as a
counterweight to the increased power of the Interior Ministry. The PGR’s budget increased much
less during the Felipe Calderón Administration (2006-2012) than those of the SSP or the military.
Per reforms enacted in December 2013, the PGR will eventually be replaced by an independent
Prosecutor General’s Office.
Additionally, President Peña Nieto sought and achieved the dissolution of the Ministry of Public
Administration, Mexico’s anti-corruption authority. Peña Nieto has proposed replacing that entity
with an anti-corruption commission that would reside within the Treasury Department and have
the power to issue administrative sanctions for corruption found in all levels and branches of
government. The Mexican Senate approved legislation to establish the autonomous anti-
corruption commission in December 2013.
Leadership
Although Mexico has an unusually long transition period from one presidency to the next – five
months – incoming leaders do not generally announce their cabinet appointments until
immediately prior to assuming office. President Peña Nieto selected many of his close
confidantes and transition team leaders for key positions in his government. Many analysts
maintain that Peña Nieto’s appointments reflect his desire to reestablish a strong presidency
backed by certain key ministers.
Within Peña Nieto’s cabinet, two key leaders are the Ministers of Finance and the Interior. Luis
Videgaray Caso, who served as the Transition Team’s General Coordinator, is the Secretary of
Finance, a post which he also held in the state of Mexico during Peña Nieto’s governorship.
Miguel Angel Osorio Chong, the Transition Team’s General Coordinator for Political and
Security Issues, is head of the powerful Interior Ministry. Osorio Chong served as governor of
Hidalgo, which borders the state of Mexico, when Peña Nieto governed. The remainder of the
cabinet consists of a combination of younger PRI leaders with technical expertise and
postgraduate education abroad; senior PRI politicians, many of whom served as governors; and a
few individuals from outside the party.7
Thus far, Peña Nieto’s government has appeared to avoid the public infighting that occurred
among some of former President Calderón’s ministers and to manage public relations effectively.
The government has tightly controlled the message it seeks to project, which has emphasized its
commitment to implementing structural reforms to move Mexico forward, rather than focusing on
its efforts against organized crime (as Calderón did). Many assert that this strategy has improved
Mexico’s image abroad. Others have criticized the government’s communications strategy for
seeking to quash criticism of its policies and downplaying security concerns.8

6 The size of the Gendarmerie has been significantly scaled back from what the government had originally proposed. It
is reportedly scheduled to begin operating with roughly 5,000 officers in mid-2014. Many questions remain about how
responsibilities will be divided between the Federal Police, the Gendarmerie, and the military. Gabriel Stargardter and

Priorities
Upon his inauguration, President Peña Nieto announced a reform agenda with specific proposals
under five broad pillars: (1) reducing violence; (2) combating poverty; (3) boosting economic
growth; (4) reforming education; and (5) fostering social responsibility. Pillars one and three
echoed Peña Nieto’s core campaign pledges to prioritize violent crime reduction over combating
international criminal groups and to boost Mexico’s anemic growth rates (which had averaged
just 2% since 2000). Those pledges have thus far proven difficult to fulfill. While organized
crime-related homicides continue to trend downward as they have since 2012, extortions and
kidnappings are increasingly occurring.9 The spread of self-defense groups throughout Mexico
and the government’s inability to quell unrest in Michoacán have tested the government’s security
strategy.10 In addition, the government’s lack of investment, combined with weak demand for
Mexican exports and a slowdown in the construction industry, caused GDP growth to drop to its
lowest level since the 2009 recession. Peña Nieto posted a lower first year approval rating
(49.7%) than his two PAN predecessors.11
Despite these difficulties, investors and analysts have widely praised President Peña Nieto and his
top advisors for focusing their attention and political capital on shepherding structural reforms
through the Mexican Congress. Many of the reforms that Peña Nieto has prioritized have long
been recommended by the Organization for Economic Cooperation and Development (OECD)
and others as crucial for boosting Mexico’s competitiveness. As discussed below, Peña Nieto has
proven much more adept at engaging in the type of multi-party negotiations needed to enact
legislation when lacking a congressional majority than former Presidents Ernesto Zedillo, Vicente
Fox, or Felipe Calderón. No Mexican president has enjoyed a congressional majority since 1997.
The Pact for Mexico and Structural Reform
On December 2, 2012, leaders of the conservative PAN and leftist PRD surprised many analysts
by signing on to President Peña Nieto’s “Pact for Mexico” agreement containing 95 agreements
on key issues facing the country. Those agreements provided a baseline for the parties to debate
legislative proposals. While some opposition legislators later balked at their leaders’ decisions to
endorse the PRI-led pact, the Congress approved education and telecommunications reform
legislation, two measures that Peña Nieto had identified as short-term priorities, as well as a long-
stalled crime victim’s law during its first session (February-April 2013).12

Mexico: Background and U.S. Relations

Table 1. Key Reforms Enacted During Peña Nieto’s First Year

Education Reform: gives the government, rather than the union, control over hiring and firing teachers;
creates a new entity to evaluate teachers; and, increases funding for education, including full-day schooling.

Telecommunications Reform: increases consumers’ access to more affordable and reliable TV, radio,
internet, and mobile phone services and creates an independent entity, the Federal Institute of
Telecommunications (IFETEL), to regulate radio, television, and telecommunications companies.

Financial Reform: increases access to credit, particularly for small-and medium-sized businesses and creates
more competition in the banking sector.

Fiscal Reform: raises additional revenue by increasing income taxes for upper income earners, upping the value
added tax (VAT) to16% in northern border states (where it had been 11% before), and creating new taxes on
stock market profits, as well as sugary beverages and other snack foods.

Energy Reform: creates several different types of contracts, including production-sharing and licensing; al ows
companies to post reserves for accounting purposes; gives Petroleos Mexicanos (Pemex) budget autonomy;
establishes a sovereign wealth fund; creates new regulators; and removes the union from the Pemex board.

Political Reform: provides for the re-election of federal deputies for up to four terms beginning in 2015 and of
senators for up to two terms beginning in 2018, the reelection of mayors, and local legislators; replaces the
current Attorney General’s Office with an independent Prosecutor General’s Office; creates a new national
electoral institute, and calls for the annulment of an election if there is evidence that a party engaged in
“systematic” violations of campaign finance restrictions.

Unified Code of Criminal Procedure (CPC): One reform amended the Constitution so that the Congress
can establish a unified CPC for the entire country. The CPC has been approved by the Senate and is awaiting
consideration by the Chamber.

During his first year, Peña Nieto benefitted from the fact that the PAN and the PRI agreed on
many of the economic reforms that needed to be enacted. Some of the reforms passed with PAN-
PRI support, such as the energy reforms, were similar to efforts that PAN Presidents had put forth
in the past only to have them blocked by the PRI. Prospects for reform brightened after no party
dominated the July 7, 2013, state and municipal elections. While the PRI remained the dominant
party nationally, the PAN retained control of Baja California (which it has governed since 1989)
and the PRD and smaller parties garnered unexpected gains in other regions of the country.
Although many of the aforementioned reforms still need to have implementing legislation passed
in order to take effect, many were constitutional reforms requiring two thirds votes of both
chambers of Congress and the approval of a majority of state legislatures. The PRI had to garner
support from other parties to pass those reforms. The fiscal reform, passed with PRD support,
increased taxes on corporations and high-wage earners rather than applying the value added tax to
food and medicines. The energy reform created more avenues for private participation in the
energy sector than the PRI had originally proposed (per the PAN’s pressure).
This year will likely be a critical test of President Peña Nieto’s ability to translate broad reforms
into specific laws and regulations that will have an impact on Mexico’s political and economic
system. There is a real chance that some reforms enacted in 2013 may be diluted or blocked
entirely due to opposition from vested interest groups. For example, even though the government
arrested Elba Esther Gordillo, the formerly powerful head of the Mexican National Education
Worker’s Union (SNTE) on corruption charges in February 2013, protests from members of that
entity and another national teacher’s union proved fierce and sustained. Protesting teachers
prompted the Mexican Congress to water down legislation that would have required teachers to

submit to periodic performance evaluations or face sanctions. The PRD has at least temporarily
withdrawn from the Pact for Mexico, and pledged to mobilize court challenges and popular
referenda against the energy reform. According to PRD leaders, some 40% of the Pact for
Mexico’s 95 goals remains unfilled, particularly those dealing with human rights, justice, and
rural development.13
Security Policy, Institutional Reform, and Corruption
On December 17, 2012, President Peña Nieto outlined a strategy that aims to achieve a “Mexico
in Peace” where human rights are protected by implementing a “state” security policy that
involves binding commitments from all levels of government and civic participation. The six
pillars of the strategy include (1) planning; (2) prevention; (3) protection and respect of human
rights; (4) coordination; (5) institutional transformation; and (6) monitoring and evaluation.
President Peña Nieto has said that although his government will not abandon the fight against
organized crime, the primary goal of his security strategy is to reduce violent crime. The Peña
Nieto government’s approach has been described as more “low key” than that of Calderón, who
tended to publicize kingpin arrests and drug seizures. The government’s emphasis on prevention
has been demonstrated by the creation of a national prevention program with a $9 billion budget
that includes socioeconomic, education, infrastructure, and drug treatment programs.
Fourteen months into his administration, the jury is still out on Peña Nieto’s security strategy.
Some analysts argue that Peña Nieto has yet to define his security priorities and how they will be
achieved, while others assert that he has quietly maintained an approach similar to that of former
President Calderón.14 Despite restrictions placed on U.S. security agencies working in Mexico,
U.S. intelligence reportedly helped Mexican marines successfully track and arrest Miguel Angel
Treviño Morales (“Z-40”), the leader of Los Zetas, in July 2013.15 Some 69 other top drug
traffickers have also been arrested.16 Bilateral cooperation has suffered at times, however,
including after a Mexican court has overturned the conviction of Rafael Caro Quintero, a kingpin
convicted of kidnapping and murdering DEA agent Enrique Camarena in 1985.17 (See “Security
and U.S. Assistance through the Mérida Initiative” below.)
Organized crime-related violence continued to decline in 2013 as it had during the last year of the
Calderón government, yet serious security challenges remain in many parts of Mexico. President
Peña Nieto has said that organized-crime violence declined by 30% in 2013.18 Since the
government is no longer publicly releasing information on trends in organized crime-related
killings as opposed to all homicides, it is difficult to analyze the security situation with precision.

counterdrug cooperation declined dramatically until the late 1990s due to U.S. mistrust of Mexican counterdrug
officials and concerns about the Mexican government’s tendency to accommodate drug leaders. For more on Quintero,

Mexico: Background and U.S. Relations

According to Mexican government figures, all homicides fell by 16.5% as compared to 2012.19
Nevertheless, kidnappings increased in 2013, with police from all levels of government among
those accused of carrying them out.20
While violence has declined in some parts of northern Mexico, it has spiked in the interior of the
country and along the Pacific Coast, particularly in Michoacán. The failure of past federal efforts
to quell violence and reestablish state presence there have led to the development of civilian
“self-defense groups” over the course of the last year that have recently engaged in violent
clashes with the Knights Templar drug trafficking organization. President Peña Nieto has
designated a special envoy for the state, sent in additional troops and Federal Police, and elected
to absorb the self-defense groups into “rural defense corps” under the authority of the military.21
It remains to be seen how and whether federal forces, working in collaboration with state
officials, will be able to combat drug traffickers, absorb and control the civilian groups, and
establish the rule of law. If left unaddressed, some analysts fear that vigilante groups could morph
into paramilitary forces whose interests do not necessarily align with those of the government, as
happened in Colombia, and/or form close ties with competing criminal groups.22
Reforming Mexico’s corrupt and inefficient criminal justice system is widely regarded as a
crucial for combating criminality, strengthening the rule of law, and better protecting citizen
security and human rights in the country. The Peña Nieto government has taken some steps to
accelerate implementation of judicial reform, establish national police standards, and investigate
cases of forced disappearances. Human rights groups and security analysts assert that much more
needs to be done to bolster institutional reform, anticorruption efforts, and respect for human
rights.23 According to the Economist Intelligence Unit, Peña Nieto’s government has “essentially
taken its eyes off … crime and corruption to concentrate on structural reform.”24
Foreign Policy
President Peña Nieto has prioritized promoting trade and investment in Mexico as a core goal of
his Administration’s foreign policy. José Antonio Meade, Secretary of Foreign Relations, served
in finance positions for the Fox and Calderón Administrations including, most recently, Secretary
of Finance. President Peña Nieto and Secretary Meade have not only reoriented U.S.-Mexican
relations to focus on economic issues, but sought to create closer trade ties with Europe, Asia, and
the rest of Latin America, including Cuba. President Peña Nieto visited China early in his
Administration and hosted Chinese Premier Xi Jinping for a state visit to Mexico. His
government is actively involved in negotiations for a Trans Pacific Partnership25 trade agreement

as well as economic integration efforts with the pro-trade Pacific Alliance countries of Chile,
Colombia, and Peru. Promoting investment opportunities that have been created by Mexico’s
recent energy reforms may figure prominently in Mexico’s foreign policy as well.
Economic and Social Conditions
Over the last 25 years, Mexico has transitioned from a closed, state-led economy to an open
market economy. While the transition began in the late 1980s, it accelerated after Mexico entered
into the North American Free Trade Agreement (NAFTA) with the United States and Canada in
1994. Since NAFTA, the Mexican economy has increasingly become a manufacturing-for-export
nation, with exports representing some 32% of Mexico’s GDP, up from 10% twenty years ago.
Mexico remains a major U.S. crude oil supplier, but its top exports to the United States have
diversified to include automobiles and auto parts, television receivers, and other manufactured
goods. Mexico has entered into 12 free trade agreements (FTAs) involving 44 other countries.26
Despite attempts to diversify its economic ties and build its domestic economy, Mexico continues
to remain heavily dependent on the United States as an export market (78% of Mexico’s exports
in 2012 were U.S.-bound), and as a source of tourism revenues, remittances, and investment.
Economic conditions in Mexico tend to follow economic patterns in the United States. When the
U.S. economy is expanding, the Mexican economy tends to grow as well. However, when the
U.S. economy stagnates or is in decline, the Mexican economy tends to decline as well, often by a
higher degree. In 2009, for example, GDP growth in the United States fell by 2.5% and Mexico’s
GDP declined by 6.5%.27
Many economists have praised the sound fiscal policies of the past two PAN administrations, but
faulted them for failing to address some of the structural issues that have constrained the
country’s growth potential. The Calderón government maintained macroeconomic stability in the
face of the 2008 global economic crisis and U.S. recession, a 2009 H1N1 swine flu epidemic that
damaged the tourism industry, and declining oil production.28 With careful economic planning,
the Mexican economy recovered from the 2009 crisis, with growth rates averaging 4.4% from
2010-2012. Despite that recovery, economists criticized the PAN’s failure to address Mexico’s
low tax base and over-reliance on declining oil revenues, weak education system, and lack of
competition in some sectors.29

Mexico: Background and U.S. Relations

Growth: Will Reforms Bring Faster GDP Growth?
Enrique Peña Nieto and his top advisors have long stressed the importance of passing structural
reforms to make the Mexican economy more competitive. During the 2012 campaign, Peña Nieto
acknowledged that the PAN had maintained a stable economy, but criticized the past two
administrations for failing to spur rapid economic growth. He identified several reasons why
Mexico’s economic growth had lagged: low productivity, insufficient access to credit, deficient
investment in infrastructure, monopolies, a large and expanding informal sector, and a continued
over-reliance on the U.S. market. To counter these deficiencies, Peña Nieto advocated a 10-point
economic plan that included, among other measures, implementing legislation to counter
monopolistic practices, passing fiscal reform, opening up the oil sector to private investment,
making farmers more productive, and doubling infrastructure investments. Peña Nieto also
endorsed an active international trade policy aimed at increasing Mexico’s trade with Asia, South
America, and other markets.
During his first year in office, President Peña Nieto shepherded historic economic reforms
through the Mexican Congress (see Table 1), but failed to maintain the economic growth rates
that Mexico had posted for the last three years of the Calderón government. Economists have
variously blamed the government’s failure to promote investment, natural gas shortages, weak
external demand, and a slowdown in Mexico’s construction industry for the country’s weak 1.2%
growth rate in 2013.30 They predict that economic growth should pick up this year, however, since
the 2014 budget will allow for increased government spending and the aforementioned structural
reforms, along with labor reforms enacted in 2012, should begin to take effect.31
Analysts have estimated that the package of reforms that was approved in 2013 could increase
annual economic growth rates by 1.0-1.5 percentage points.32 The Peña Nieto government
maintains that the recently-enacted energy reforms will result in lower energy prices, create
500,000 new jobs, and boost GDP growth by 1 percentage point by the end of his term in 2018.
JP Morgan has estimated that the energy reforms may increase annual growth rates in Mexico by
up to 0.8% and foreign direct investment (FDI) in Mexico by $20 billion per year by 2016 or
2017.33 Although it is difficult to predict how increasing private participation in Mexico’s oil and
gas sectors will affect the country’s economic development, skeptics see reason to doubt the
government’s positive predictions, warning of the potential for corruption and waste.
Combating Poverty
President Peña Nieto sought to boost tax revenues in order to establish a universal social safety
net with social security and unemployment insurance that builds upon the last two governments’
provision of nearly universal access to health care. Mexico has long had relatively high poverty
rates for its level of economic development (45.5% in 2012),34 particularly in rural regions and

among indigenous populations. Some assert that conditions in indigenous communities have not
measurably improved in the twenty years since the Zapatistas (Ejército Zapatista de Liberación
Nacional
), a leftist revolutionary group based in Chiapas, launched an uprising for indigenous
rights in 1994.35 Poverty has historically been one of the factors fueling illegal emigration.
Finance Minister Videgaray has acknowledged the contributions that social programs have made
to preventing Mexicans from falling into poverty in times of crisis (including the 2009 recession),
but maintained that boosting GDP growth and job creation is needed to reduce poverty rates.
President Peña Nieto’s 2013 budget provided expanded access to federal pensions, created a new
life insurance program for female heads of household, and increased funding for the
Oportunidades (Opportunities) conditional cash transfer program.36 Oportunidades is currently
being redesigned to encourage its beneficiaries to engage in productive projects; a package of
agrarian reforms to bolster productivity in rural communities has also been announced.
U.S. Relations and Issues for Congress
As Mexico is experiencing a major domestic shift in power from PAN to PRI rule, U.S.-Mexican
relations are also evolving. While President Barack Obama and President Peña Nieto both face a
full slate of domestic challenges, analysts have urged them to work together on issues that are of
critical importance to both countries, particularly those aimed at boosting trade and job creation.
President Obama embraced President Peña Nieto’s desire to bolster economic ties and to focus on
a broad array of bilateral issues rather than focusing predominantly on security issues at meetings
held in November 2012 and in May 2013.37
Even as revelations of alleged U.S. surveillance of Mexican leaders and the recent execution of a
Mexican national on death row in Texas38 have strained relations, both governments have
emphasized that cooperation has continued, particularly in the economic realm. Vice President
Joseph Biden chaired the first annual High Level Economic Dialogue with Mexico in September
2013, at which both governments adopted a work plan aimed at promoting competitiveness and
connectivity, fostering productivity and innovation, and partnering for regional and global
leadership.39 President Obama will build upon those meetings, as well as Secretary of State John

Mexico: Background and U.S. Relations

Kerry’s recent meeting with Secretary Meade, with another trip to Mexico scheduled for February
19, 2014, for a North American Leader’s Summit with President Peña Nieto and Canadian Prime
Minister Stephen Harper.
The U.S. Congress has maintained long-standing interest in a broad range of issues dealing with
Mexico, a country with whom the United States shares a nearly 2,000-mile border and $500
billion in annual trade. In recent decades, the top issues of congressional interest on the bilateral
agenda have been migration/border security; trade (NAFTA implementation and disputes); and
drug trafficking and security. Security issues had generally overtaken migration and trade matters
since 2008 as a result of Mexico receiving U.S. foreign assistance through the Mérida Initiative,
but in 2013 migration and trade again moved to the top of the bilateral agenda. The potential for
greater energy cooperation with Mexico has emerged as a new issue of interest, while water
disputes in the Rio Grande region have reemerged as an area of contention.
Some bilateral issues may require immediate congressional action in order to advance, while
others may lend themselves more to long-term oversight. For example, migration and border
security cooperation could be substantially overhauled should Congress enact comprehensive
immigration reform. Congress has already weighed in on current trade and water disputes. At the
same time, Congress is considering continued funding for the Mérida Initiative and related
domestic initiatives aimed at combating transnational crime and strengthening the rule of law in
Mexico that are well underway. Congressional concerns about improving human rights conditions
and strengthening democracy in Mexico also lend themselves to long-term oversight.
Migration and Border Security
Immigration policy has been a subject of congressional concern over many decades, with much of
the debate focused on how to prevent unauthorized migration. Mexico’s status as the largest
source of U.S. migrants and a continental neighbor means that U.S. migration policies—including
stepped up border and interior enforcement—have primarily affected Mexicans.40 As a result,
immigration is a central issue in U.S.-Mexican relations.
Since 1986, the United States has taken a number of steps to tighten border security and
strengthen immigration enforcement,41 while also legalizing about 3 million people. Yet the
estimated number of unauthorized immigrants in the United States still has grown from about 3.2
million in 1986 to about 11.1 million in 2011.42 At a broad level, today’s immigration debate is
focused on additional steps to strengthen immigration enforcement and border security, potential
legalization provisions for certain unauthorized immigrants, and possible changes to the rules
governing lawful immigration flows. An overarching question is whether these three issues
should be considered together as “comprehensive immigration reform or whether they should be

40 Mexicans are by far the largest group of immigrants in the United States, accounting for about 12 million people in
2012, or 30% of all current U.S. immigrants. (Chinese immigrants are the next largest group, at 5%.) About half of
Mexican immigrants are unauthorized, representing about 58% of the U.S. unauthorized population. See Jeffrey Passel,
D’Vera Cohn, and Ana Gonzalez-Barrera, Net Migration from Mexico Falls to Zero—and Perhaps Less, Pew Hispanic
Center, Washington, DC, May 3, 2012. Mexicans account for an even larger share of unauthorized aliens apprehended
(93% since FY1991) and aliens formally deported (72%); see CRS Report R42560, Mexican Migration to the United
States: Policy and Trends
, by William A. Kandel, Clare Ribando Seelke, and Ruth Ellen Wasem.

taken up separately (sometimes referred to as “piecemeal reform”). Some Members of Congress
have argued that legalization only should be considered—if at all—after enforcement measures
have been successfully implemented.
Since the mid-2000s, successive Mexican governments have supported efforts to enact
comprehensive immigration reform in the United States, while being careful not to appear to be
infringing upon U.S. congressional authority to make and enforce immigration laws.43 The
Mexican government has pledged to enforce legal emigration, increase security along its northern
and southern borders, and create opportunities for workers in Mexico so that fewer individuals
will emigrate. Mexico has aggressively combated transmigration by unauthorized migrants
crossing Mexico bound for the United States and worked with U.S. law enforcement to combat
alien smuggling and human trafficking. Due to a number of factors, illegal emigration from
Mexico is estimated to be at a 40-year low.44 Still, corruption remains endemic within Mexico’s
National Migration Institute (the entity within the Interior Ministry that enforces immigration
laws);45 Mexico’s southern border continues to be porous and insecure; and rural poverty and a
dearth of formal employment opportunities persist.
President Peña Nieto, like former President Calderón, is unlikely to promise Mexicans that he can
affect immigration reform efforts in the U.S. Congress or reach a bilateral accord with the Obama
Administration. Both leaders saw how Former President Vicente Fox’s failure to secure a bilateral
immigration accord with the United States in 2001 proved to be a major blow to his
administration.46 Nevertheless, Peña Nieto has pledged his full support for efforts to enact
comprehensive immigration reform, and is likely to continue Mexico’s efforts to improve border
security, enforce its migration policies in a humane way, and create jobs in order to discourage
illegal emigration.
Several migration-related issues have concerned the Mexican government. Mexico has protested
the alleged excessive use of force by U.S. agents on the border; defended the rights of Mexican
migrants in the United States, regardless of their status; and is challenging state laws against
illegal immigration.47 Record numbers of removals (deportations) under the Obama
Administration, as well as certain removal procedures, such as the treatment of unaccompanied
minors and removals that release migrants into violent border regions at night, have been issues
of concern.48 Recent increases in Mexicans from some regions seeking asylum in the United

43 For background, see CRS Report R42560, Mexican Migration to the United States: Policy and Trends.
44 Researchers attribute this decline to the U.S. recession, stepped-up U.S. border security and interior enforcement,
increasing abuses of migrants by smugglers and transnational criminal organizations, and expanding job opportunities
in Mexico, among other factors. Jeffrey Passel, D'Vera Cohn, and Ana Gonzalez-Barrera, Net Migration from Mexico

46 President Fox and President George W. Bush met five times during the first nine months of 2001, and on September
6, 2001, the two presidents announced a framework agreement to negotiate a major bilateral migration accord. The
agreement would have included a Mexico-specific temporary worker program, collaborative border enforcement,
legalization for certain unauthorized Mexicans in the United States, and new investments in Mexican communities of
origin aimed at reducing illegal outflows. The possibility of a U.S.-Mexico migration accord faded after the 9/11
terrorist attacks.
47 The Mexican government has filed amicus curiae (i.e., “friend of the court”) briefs in lawsuits seeking to block the
immigration laws in Arizona, Alabama, Georgia, South Carolina, and Utah.

Mexico: Background and U.S. Relations

States due to threats of violence in their communities and a rise in Central American migrants in
transit through Mexico has been a concern of both governments. Emigrants from Mexico and
Central America have increasingly become victims of kidnapping and abuses by organized crime,
sometimes in collusion with corrupt Mexican officials.49
Immigration reform received substantial attention in both chambers during the first session of the
113th session of Congress. On June 27, 2013, the Senate passed the Border Security, Economic
Opportunity, and Immigration Modernization Act (S. 744) by a yea-nay vote of 68-32. This
comprehensive immigration reform bill would roughly double recent investments in border
security; require all employers eventually to use an electronic employment eligibility verification
system similar to the current E-Verify program; establish three different legalization programs
designed to potentially offer lawful permanent residency to most existing unauthorized
immigrants; and substantially revise rules for both permanent and temporary immigration to the
United States.50 Many unauthorized Mexicans in the United States would potentially be eligible to
obtain legal status under S. 744, and Mexicans also would be among those eligible for new
permanent and temporary visas that would be created by the bill. While border security is seen as
a core feature of comprehensive immigration reform, some people have argued that S. 744 would
devote too much money to border fencing, personnel, and surveillance, possibly to the detriment
of border communities and legal cross-border flows.
In the House, five different immigration bills received committee attention in 2013.51
• In May, the House Homeland Security Committee reported favorably on the
Border Security Results Act of 2013 (H.R. 1417), which would require the
Department of Homeland Security (DHS) to develop a comprehensive strategy to
secure the southern border, along with new border security metrics.
The House Judiciary Committee (with jurisdiction over immigration issues) marked up four bills
in June 2013.
• The Strengthen and Fortify Enforcement Act (SAFE Act, H.R. 2278) focuses on
interior immigration enforcement. Among other provisions, the SAFE Act would
encourage states and localities to play a larger role in immigration enforcement
and heighten penalties for violations of federal immigration law, including by
establishing a new criminal penalty for illegal presence in the United States.
• The Agricultural Guest Worker Act (H.R. 1773) would create a new H-2C
temporary agricultural worker visa designed to be more flexible than the existing
H-2A visa, which eventually would be eliminated under the bill.
• The Supplying Knowledge-based Immigrants and Lifting Levels of STEM Visas
Act (SKILLS Visa Act, H.R. 2131) would expand permanent and temporary visa
programs for high-skilled workers, and would eliminate the existing Diversity
Visa program.

• The Legal Workforce Act (H.R. 1772) would require all employers eventually to
use the E-Verify electronic employment eligibility verification system, while also
creating a larger role for states in the enforcement of employment-related
immigration laws.
All four Judiciary Committee bills were ordered reported on mainly party line votes, and all four
bills were referred to other committees with jurisdiction over them. House Members appear to be
divided about which of these bills, if any, should be brought to the House floor. Some House
Members also favored a legalization program for certain unauthorized immigrants brought to the
United States as children.52
Enacted on January 17, 2014, the FY2014 Consolidated Appropriations Act (P.L. 113-76)
provides funding for additional customs inspectors and infrastructure at the U.S.-Mexico border.
Those increases may help address some of the concerns that have been raised about the need to
ensure that the need for border security is balanced with the need to facilitate trade and reduce
border wait times.
As part of this broader debate about immigration policy and border security, one question that
may arise is the degree to which U.S. immigration policy should treat Mexico as a “special case”
on certain immigration questions given the sheer size of the bilateral flow of migrants and
Mexico’s status as America’s continental neighbor.53 Mexico enjoyed such status during and after
World War II, when the United States and Mexico negotiated a Mexico-specific temporary
worker program, known as the Bracero program. In addition, Mexican President Vicente Fox and
U.S. President George W. Bush reached agreement on a bilateral framework for comprehensive
immigration reform in 2001, though negotiations were abandoned following the September 2001
terrorist attacks against the United States. Under S. 744 as passed by the Senate in June 2013, the
U.S. Secretary of State, in coordination with DHS and in consultation with Congress, would be
required to develop a strategy to address unauthorized transit migration through Mexico to the
United States. The strategy would include steps to enhance the training of border and law
enforcement personnel in Mexico and certain Central American states, and to educate the
nationals of such countries about certain risks associated with illegal migration to the United
States.
As Congress carries out its oversight function, questions that may arise include How well is
Mexico fulfilling its pledges to increase security along its northern and southern borders and to
enforce its immigration laws? What is Mexico doing to address the root causes of emigration?
What is the current level of bilateral cooperation on border security and immigration matters, and
how might that cooperation be improved? Should Mexico be treated as a “special case” on
immigration questions?

Trade: North American Integration and the Trans-Pacific
Partnership (TPP)54

The bilateral trade relationship with Mexico is of key interest to Congress because of Mexico’s
proximity, the high volume of U.S. trade with Mexico, and the strong cultural ties between the
two countries. The U.S. and Mexican economies are linked through the North American Free
Trade Agreement (NAFTA), which has been in effect since 1994. Since the implementation of
NAFTA, total U.S. trade with Mexico has increased by 506%, with the value of total bilateral
trade reaching some $494 billion in 2012.55 Mexico ranks third as a source of U.S. imports, after
China and Canada, and second, after Canada, as an export market for U.S. goods and services.
The value of U.S. FDI in Mexico has also increased by more than 400%.56 Most studies show that
the net economic effects of NAFTA on both the U.S. and Mexican economies have been small but
positive, though there have been adjustment costs to some sectors. Congress has monitored the
implementation of NAFTA, the effects of NAFTA on the U.S. and Mexican economies, and the
resolution of NAFTA-related trade disputes. Oversight interest in NAFTA has increased recently
because of the 20th anniversary of its entry into force (January 1, 2014).57
President Peña Nieto has put forth proposals for deepening North American integration (such as
the establishment of a North American infrastructure fund) and improving efficiency at the U.S.-

Mexican border. On September 20, 2013, Peña Nieto and Vice President Biden announced plans
to enhance cooperation in border trade and security as part of their High-Level Economic
Dialogue. Describing the U.S.-Mexican border as the “busiest in the world,” generating over
$500 billion of annual bilateral trade, President Peña Nieto stated that a goal of the initiative is to
streamline trade and improve border crossing infrastructure so that the transit of both people and
trade will become more efficient, faster, and safer.58
In its legislative and oversight capacities, the 113th Congress may face numerous issues related to
trade that could affect U.S.-Mexican economic relations. For example, the Obama Administration
has made the proposed Trans-Pacific Partnership (TPP)59 free trade agreement a top trade priority.
The United States, Canada, and Mexico, along with nine other countries,60 are participating in the
TPP negotiations. The United States has sought to go beyond current U.S. FTAs in its proposed
rules chapters for the TPP, which may have implications for NAFTA in several areas. For
example, if agreement is reached on a TPP, all three NAFTA countries may need to adhere to
stronger and more enforceable labor and environmental provisions and more stringent intellectual
property rights (IPR) provisions.
The 113th Congress is also likely to continue monitoring NAFTA’s institutions. Those include the
bilateral Border Environment Cooperation Commission (BECC), located in Ciudad Juárez,
Mexico, and the North American Development Bank (NADBank), headquartered in San Antonio,
Texas. In 2011, the NADBank’s mandate was broadened beyond promoting and financing
environmental protection projects along the border to also include projects aimed at developing
clean energy. Some U.S. and Mexican policymakers have supported broadening the functions of
NADBank further to include port infrastructure. NADBank officials have offered to leverage
public-private partnerships and other financial mechanisms to help fund and coordinate border
infrastructure (roads and port projects among others), although under the bank’s mandate it can
only support projects with an environmental focus. NADBank is in the process of doing a report
for both governments regarding border infrastructure projects and potential funding mechanisms.
Experts have proposed ideas that Congress might consider to make North American industries
more competitive and hasten regional integration. Some proposals that have emerged include
calls for rethinking the current trade relationship under NAFTA by broadening the scope of North
American integration and cooperation. One idea, for example, is to develop a North American
Investment Fund to help close the income gap between Mexico and its northern neighbors. Others
include setting up a Customs Union in North America, similar to that of the European Union, with
a common external tariff to facilitate trade and deepen North American integration; developing a
cooperative approach on immigration; and promoting regulatory convergence.61
Finally, Congress may play a significant role in determining when and how outstanding trade
disputes with Mexico are resolved. The U.S. and Mexican governments resolved a long-standing
trade dispute in 2011 involving NAFTA trucking provisions62 and settled a tomato trade dispute in

early 2013. However, pending disputes include issues related to dolphin-safe tuna labeling and
meat labeling, among other issues.
In the trade realm, potential questions for congressional consideration include how U.S.-Mexican
trade and economic ties can be deepened, how efficiency on the border can be improved without
compromising security, and how weaknesses in NAFTA can be addressed.
Security and U.S. Assistance through the Mérida Initiative63
Violence perpetrated by warring criminal organizations has threatened citizen security and
governance in parts of Mexico and overwhelmed the country’s justice sector institutions.
Although the violence has declined since late 2011, it likely claimed more than 60,000 lives
during the Calderón Administration.64 According to government estimates, at least 6,000
additional organized crime-related deaths occurred during the first six months of the Peña Nieto
Administration.65 This violence has increased congressional concerns about stability in Mexico
and about the possibility of violence spilling over into the United States.
U.S.-Mexican security cooperation increased significantly as a result of the development and
implementation of the Mérida Initiative, a bilateral security partnership announced in 2007 that
has involved U.S. assistance to Mexico. From FY2008 to FY2013, Congress appropriated $2.1
billion in Mérida assistance for Mexico, roughly $1.3 billion of which has been delivered. The
Obama Administration asked for $183 million in its FY2014 request. Final FY2014 aid amounts
are not yet available, but P.L. 113-76 recommends providing at least $200 million in aid to
Mexico subject to human rights conditions.66 It also requires a report within 45 days of the bill’s
enactment, which occurred on January 17, 2014, assessing progress made in Mérida
implementation and examining how criminal groups in Mexico have evolved and the best ways to
combat them, including their illicit financing activities.67
Whereas U.S. assistance initially focused on training and equipping Mexican counterdrug forces,
it now places more emphasis on addressing the weak institutions and underlying societal
problems that have allowed the drug trade to flourish in Mexico. The current Mérida strategy
focuses on four pillars: (1) disrupting organized criminal groups, (2) institutionalizing the rule of
law, (3) building a 21st century border, and (4) building strong and resilient communities. While
bilateral efforts have yielded some positive results, the weakness of Mexico’s criminal justice
system has hindered the effectiveness of some anti-crime efforts.
Peña Nieto has vowed to continue U.S.-Mexican security cooperation, albeit with more emphasis
on reducing violent crime in Mexico. Peña Nieto has begun to adjust the process and priorities of

Mexico: Background and U.S. Relations

U.S.-Mexican efforts, adjustments which President Obama has pledged to support.68 The Interior
Ministry is now the primary entity through which Mérida training and equipment requests are
coordinated and intelligence is channeled. The Mexican government is requesting increased
assistance for judicial reform and prevention efforts, but limiting U.S. involvement in some law
enforcement and intelligence operations.69 Peña Nieto’s security strategy appears to dovetail well
with pillars two and four of the Mérida strategy, and his economic plans embrace pillar three’s
goals for border modernization, but the path forward for efforts under pillar one remains
somewhat unclear.
President Peña Nieto may also call the U.S. government to report on progress in meeting its
domestic pledges under the Mérida Initiative to address drug demand and the illicit trafficking of
firearms and bulk currency to Mexico. His government supports efforts to enact gun control and
to combat gun trafficking from the United States to Mexico. It has identified money laundering as
an area in which bilateral efforts could be intensified.
The 113th Congress has held hearings70 examining how the Mérida Initiative is being adjusted to
align with the Peña Nieto government’s priorities and is withholding $95 million in Mérida aid
pending further information from the Obama Administration on that topic.71 Congressional
consultation will be needed should the State Department seek to reprogram some of the funding
in the pipeline for Mérida, or seek new funding to align with Mexico’s new priorities. Should
differences occur between Mexican and U.S. priorities, Congress may choose to weigh in on how
those differences should be resolved. While the Peña Nieto government’s capture of the leader of
Los Zetas may have assuaged some concerns about his commitment to combating organized
crime, a Mexican court’s reversal of the conviction of Rafael Caro Quintero raised U.S.
concerns.72 Mexico has issued a warrant for him to be re-arrested. For its part, the Mexican
government continues to be concerned about the adequacy of U.S. efforts to respond to the
allegations of National Security Agency spying on its leaders.73
Possible questions for oversight may include the following.
• What have been the results of the Mérida Initiative thus far?
• How is the State Department measuring the efficacy of Mérida programs?
• How are Mérida programs being affected by the Peña Nieto government’s new
security strategy?
• How is coordination going with the new government?

Mexico: Background and U.S. Relations

• To what extent is the Mexican government moving judicial and police reform
efforts forward, and how is U.S. assistance supporting those reforms?
Human Rights and Judicial Reform
Congress has expressed ongoing concerns about human rights conditions in Mexico. These
concerns have intensified as U.S. security assistance to Mexico has increased under the Mérida
Initiative. Congress has continued monitoring adherence to the “Leahy” vetting requirements that
must be met under the Foreign Assistance Act (FAA) of 1961 as amended (22 U.S.C. 2378d)74
and annual Department of Defense (DOD) appropriations75 in order for Mexican security forces76
to receive U.S. support.77 Congress has also conditioned U.S. assistance to the Mexican military
and police on compliance with certain human rights standards, while simultaneously providing
funding to support human rights training for security forces and to protect groups vulnerable to
human rights abuses (such as the press and human rights defenders). The primary goal of these
efforts has been to ensure that U.S.-funded anticrime efforts are carried out in a way that respects
human rights and strengthens the rule of law in Mexico.
U.S. assistance to Mexico has increasingly focused on supporting the Mexican government’s
efforts to reform its corrupt and inefficient judicial system, both as a means to make anticrime
efforts more effective and to strengthen the rule of law in Mexico.78 Congress has targeted money
to support Mexico’s transition from an inquisitorial justice system to an oral, adversarial, and
accusatory system that should strengthen human rights protections for victims and the accused.
Congress has also increased funding for rule of law (ROL) programs in Mexico, asked the State
Department to report on how U.S. programs are helping to achieve judicial and police reform in
Mexico (H.Rept. 112-331), and expressed support for future ROL funding (H.Rept. 113-185).79
U.S. policymakers are likely to follow how the Peña Nieto government moves to fulfill its
pledges to enact a federal criminal procedure code to hasten reform at the federal level and
increase support to states transitioning to the new system.
Human rights groups initially expressed satisfaction that President Peña Nieto had adopted a pro-
human rights discourse and promulgated a law requiring state support for crime victims and their
families.80 They have since been underwhelmed with his government’s efforts to promote and

74 The codified Leahy law (22 U.S.C. 2378d) prohibits the furnishing of assistance authorized by the FAA and the
Arms Export Control Act, as amended, (AECA) to any foreign security force unit that is credibly believed to have
committed a gross violation of human rights.
75 A provision in the annual DOD appropriations legislation prohibits the use of DOD funds to support any training
program involving a unit of a foreign security or police force if the unit has committed a gross violation of human
rights. P.L. 113-76 expands that prohibition to cover DOD equipment assistance programs as well.
76 There is no FAA definition for the term “security force.” DOD defines the term as “duly constituted military,
paramilitary, police, and constabulary forces of a state.”(DOD Dictionary of Military and Associated Terms, DOD
Joint Publication 1-02, http://www.dtic.mil.)

protect human rights.81 Some have therefore urged U.S. policymakers to closely monitor the Peña
Nieto government’s compliance with conditions on Mérida assistance and to continue rigorous
vetting of Mexican individuals and units slated to receive U.S. training and equipment.82 How the
Peña Nieto government moves to improve the ability of Mexico’s civilian institutions to
investigate and prosecute cases of human rights abuses by security forces, enhance enforcement
of prohibitions against torture and other mistreatment, and strengthen protection for human rights
defenders, the media, and other vulnerable groups is likely to be closely scrutinized.
The 113th Congress may choose to augment Mérida Initiative funding for human rights programs,
such as ongoing training programs for military and police, or newer efforts, such as support for
human rights organizations. Human rights conditions in Mexico, as well as compliance with
conditions on Mérida assistance, are also likely to continue to be important oversight issues. The
State Department submitted a report in August 2012 that met the statutory requirements for
FY2012 and FY2013 funding to be released, but withheld $18 million as a matter of policy
pending further progress in key areas.83 The FY2014 Consolidated Appropriations Act (P.L. 113-
76) includes several human rights provisions regarding aid to Mexico. Those provisions withhold
15% of assistance to the Mexican military and police until the State Department reports that
progress has been made in meeting four human rights conditions.84 They also require a report
from the State Department within 60 days of the measure’s enactment (January 17, 2014) on
progress made in meeting the human rights conditions included in the FY2012 and FY2013
appropriations legislation (P.L. 112-74 and P.L. 113-6).85
U.S. policymakers may question how the Peña Nieto Administration is moving to punish past
human rights abuses, how it intends to prevent new abuses from occurring, and how the police
and judicial reforms being implementing are bolstering human rights protections.

.
83 Those areas include improving the ability of Mexico’s civilian institutions to investigate and prosecute cases of
human rights abuses; enhancing enforcement of prohibitions against torture and other mistreatment; and strengthening
protection for human rights defenders.
84 Those conditions require the Secretary of State to report that the Mexican government (1) has reformed its military
justice system to require that military abuses against civilians are investigated and prosecuted in the civilian justice
system; (2) is enforcing prohibitions against torture and the use of testimony obtained through torture; (3) is ensuring
that military and police are immediately transferring detainees to the custody of civilian judicial authorities and are
cooperating with such authorities in such cases; and, (4) is searching for the victims of enforced and involuntary
disappearances and prosecuting those responsible for such crimes. They are outlined in S.Rept. 113-81 accompanying

Mexico: Background and U.S. Relations

Mexico’s Energy Reforms and U.S. Approval of the Transboundary
Hydrocarbons Agreement86

The future of oil and gas production in Mexico is of great importance for Mexico’s economic
development and for U.S. energy security, a key congressional interest; Mexico is consistently a
top U.S. crude oil supplier. Mexico’s state oil company, Petroleos Mexicanos (Pemex),
established in 1938 as the world’s first major national oil company, remains an important source
of government revenue, but is struggling to counter the country’s declining oil production.
On December 20, 2013, President Enrique Peña Nieto signed into law constitutional reforms
related to Mexico’s energy sector aimed at reversing those declines. The reforms create several
different types of contracts, including production-sharing and licensing, allow companies to post
reserves for accounting purposes, give Pemex budget autonomy, establish a sovereign wealth
fund, create new regulators, and remove the union from the Pemex board. The Mexican Congress
has 120 days to draft the secondary legislation to implement the historic reforms to open
Mexico’s oil and natural gas sector to international companies.
The U.S. Congress has legislative and oversight interests in examining the potential implications
of Mexico’s oil and natural gas reforms on U.S. hydrocarbons imports and exports, bilateral trade
and investment, and economic conditions in Mexico. Congress recently approved the U.S.-
Mexico Transboundary Hydrocarbons Agreement87 that is intended to facilitate joint development
of oil and natural gas in part of the Gulf of Mexico (P.L. 113-67), the Bipartisan Budget Act of
2013). Other legislation has been introduced dealing with U.S. approval processes for North
American energy infrastructure, including oil and gas pipelines (H.R. 3301). The opening of
Mexico’s oil and natural gas sector could expand U.S.-Mexico energy trade and provide
opportunities for U.S. companies and investors involved in the hydrocarbons sector, as well as
infrastructure and other oil field services. If these reforms accelerate growth in Mexico (as the
government has promised) they could also benefit North American competitiveness.
Oversight questions may focus on how the Transboundary Hydrocarbons Agreement is being
implemented; the extent to which Mexico is developing independent and capable energy sector
regulators, particularly for deep water drilling; and the fairness of the terms Mexico offers to
private companies interested in investing in its hydrocarbons industry.
Water Sharing88
Management of shared water resources is significant for U.S. and Mexican interests in the border
region, as well as a contributing factor to the level of cooperation or tension between the two
countries. Multiple rivers cross or form the U.S.-Mexico border. The two principal rivers are the
Colorado River, which is predominantly in the United States but passes through Mexico on its
way to the Gulf of California (see Figure 4); and the Rio Grande, which forms the U.S.-Mexico

border in Texas (see Figure 5). These rivers are covered by long-standing international water
sharing agreements. Starting in 1906, agreements emerged to allocate the rivers’ water between
the two countries. In 1944, the two countries entered into a comprehensive water treaty, the
“Utilization of Waters of the Colorado and Tijuana Rivers and of the Rio Grande” (Treaty).89 The
1944 Treaty reconfigured an existing entity into the International Boundary and Water
Commission (IBWC),90 which is responsible for managing water in accordance with the Treaty
and resolving water-sharing disputes through amendments, called “minutes.” Recent experiences
of international water management in the two basins have contrasted, with advances in
cooperation in the Colorado River basin and increased tensions in the Rio Grande basin.
Colorado River
The Colorado River flows through seven U.S. states (Arizona, California, Colorado, Nevada,
New Mexico, Utah, and Wyoming) and into Mexico before emptying into the Gulf of California.
Some 97% of the basin is in the United States (see Figure 4).91 The 1944 Treaty requires that the
United States provide Mexico with 1.5 million acre-feet (AF) of Colorado River water annually,92
roughly 10% of the river’s average annual flow. Binational disputes have arisen over water
quantity, quality, and conservation.
Recent U.S.-Mexico water sharing discussions have coalesced around the need for better
management and conservation of both the Colorado River itself and the Colorado River Delta. As
a result, both governments, along with state officials and conservation groups from both
countries, worked with the IBWC to develop an agreement that would allocate water to Mexico
based on whether there is a surplus or drought and allow for joint investments to create greater
environmental protection, as well as greater water conservation (i.e., ability to store water) for
Mexico. These discussions culminated in the signing of Minute 319 on November 20, 2012.

90 The IBWC is an international body consisting of a United States and a Mexican section, which are overseen by the
State Department and Mexico’s Foreign Ministry, respectively.

current flows are closer to 14.4 million AF annually. “U.S., Mexico: The Decline of the Colorado River,” Stratfor

Rio Grande
While Colorado River Basin relations have been increasingly collaborative, the delivery of water
from Mexico to the United States in the Rio Grande basin has been a source of tension. The Rio
Grande is divided into two basins: the western El Paso-Juárez Rio Grande basin and the eastern
basin, which encompasses an area from Ft. Quitman to the Gulf of Mexico (see Figure 5 below).
For that eastern portion of the basin, under article 4 of the 1944 Treaty, Mexico’s water delivery
from designated tributaries must average at least 350,000 AF per year, measured in five-year
cycles.93 If Mexico fails to meet its delivery obligations for a five-year cycle because of

93 The 1944 Treaty also establishes Mexico’s right to two-thirds of the flows that feed into the Rio Grande from the six
major tributaries that enter from Mexico (Id. art. 4(A)(c)), and the United States’ right to all flows from Rio Grande
tributaries in the United States side and one-third from the six Mexican tributaries (Id. art. 4(B)).

“extraordinary drought”—a term not defined in the Treaty—it must make up the deficiency
during the next five-year cycle.
As both the U.S. and Mexican portions of the basin have experienced drought conditions since
2011, deliveries from Mexico per the 1944 Treaty have slowed, raising concerns in Texas about a
water debt. The current delivery cycle started October 25, 2010, and will end October 24, 2015.
In October 2013, the first three years of the current cycle ended with Mexico roughly 288,000 AF
(27%) behind in deliveries, based on a total target delivery for those three years of 1,050,000 AF.
Mexican interests maintain that “extraordinary drought” conditions hamper deliveries, while
Texas interests assert that the drought is easing in the Mexican portion of the basin and its
deliveries should therefore increase.

Mexico: Background and U.S. Relations

Historically, Mexico met its deliveries within the five-year cycles until the 1994 to 2003 drought.
During that drought, Mexico accrued a water debt through two water cycles. Diffusion of tensions
over the debt was the result of presidential intervention, negotiation of Minutes under the 1944
Treaty, and investments in improved water efficiency; hurricane-induced wet conditions cleared
the water debt in 2005.94
The U.S. and Mexican sections of the IBWC have met regularly since late 2012 to discuss
Mexico’s water deliveries; bilateral discussions since May 2013 also have involved high-level
State Department and Mexican government officials. Between the end of July 2013 and October
2013, the two sections had eight formal bilateral meetings, including a meeting attended by the
U.S. Ambassador to Mexico and the Mexican Foreign Ministry’s Under Secretary for North
America. Among the outcomes has been an exchange of technical data to assist in options for
future water management in the basin. Mexico delivered more than the 350,000 AF during the
third year of the cycle and reduced its water debt.95
Members of Congress have written letters to the Administration and introduced legislation related
to the Rio Grande water dispute.96 Members of Congress have also introduced legislation that
seeks to address the water shortages in Texas. H.R. 1863, introduced in April 2013, would require
the State Department to report 120 days after the enactment of the bill and annually thereafter on
efforts by Mexico to meet its Treaty deliveries of water to the Rio Grande and the benefits to the
United States occurring as a result of Minute 319. H.R. 2307 and S. 1125, introduced in May
2013, would require the State Department to report 45 days after the enactment of the legislation
and quarterly thereafter on Mexico’s water deliveries and to provide annual reports on the
benefits of Minute 319. H.R. 2307 and S. 1125 would also prohibit the Secretary of State from
continuing to implement Minute 319 if the Secretary fails to comply with the reporting
requirements included in the act.
On January 28, 2014, the House passed a new version of the 2013 farm bill (H.R. 2642). Section
11320 of the conference report (H.Rept. 113-333) accompanying H.R. 2642 would require the
State Department to submit a report within 120 days of the bill’s enactment on efforts by Mexico
to meet its Rio Grande Treaty deliveries.
On January 17, 2014, President Obama signed the FY2014 Consolidated Appropriations Act into
law (P.L. 113-76). The law requires The Secretary of State, in consultation with the IBWC
Commissioner, to report to the appropriate congressional committees within 60 days of the
measure’s enactment on actions taken to ensure that the water deficits owed by Mexico to the
United States do not increase and that allocations comply with existing bilateral water treaties.
In addition to proposed legislation, questions that Congress may confront related to the Rio
Grande basin include what are the most effective mechanisms and approaches for achieving a
Mexican water delivery regime that provides more benefit to Texas water users, and whether
interventions and investment like those employed to manage the previous water debt would be
necessary or effective. For the Colorado River basin, issues before Congress may be largely
related to oversight of the impacts and implementation of Minute 319.

Mexico: Background and U.S. Relations

Outlook
As Enrique Peña Nieto begins his second year in office, many questions remain about Mexico’s
future. How effective will President Peña Nieto be in securing congressional approval of the
secondary legislation needed to enact the reforms he signed into law in 2013? Will Peña Nieto’s
legislative agenda continue to advance even though the PRD has left the Pact for Mexico and
joined with other leftist parties and social movements to challenge energy reform and other
government actions? To what extent will the reforms that have been enacted actually be
implemented? How long will it take for average Mexicans to see benefits from the reforms?
As the 2015 mid-term elections approach, Mexicans will be increasingly concerned about
whether President Peña Nieto and the PRI have delivered on their promises to reduce crime and
bolster economic growth. Will the Peña Nieto government be able to reduce violent crimes that
affect average citizens, such as kidnapping and extortion, while still combating organized crime
and associated killings? Will the Mexican economy perform better in 2014 under the PRI? How
might this government support efforts to enact comprehensive immigration reform in the United
States?
Answers to some of these questions will depend largely upon the actions of President Peña Nieto
himself, others will depend upon external factors, while still others will be decided by a mix of
domestic and external factors. For example, Mexico would benefit immensely if certain
immigration reforms were enacted in the United States, but there is little that the Peña Nieto
government can do to support their enactment beyond pledging to reduce illegal emigration and
bolster border security. In contrast, Enrique Peña Nieto’s domestic policies can have a significant
impact on security and economic conditions in Mexico, as well as bilateral efforts in those areas.
Mexico and U.S.-Mexican relations are experiencing a time of transition. This transition may
bring about advances in some areas of the bilateral relationship, while setbacks may occur in
others. Analysts are hopeful, for example, that even as bilateral attention focuses more on trade
and energy than in the recent past, intense U.S.-Mexican security cooperation can continue.
Throughout this process, the 113th Congress is likely to closely monitor conditions in Mexico, as
well as U.S.-Mexican cooperation on key issues as part of its legislative and oversight capacities.
