Mexico: Background and U.S. Relations

Summary
Congress has maintained significant interest in Mexico, an ally and top trade partner. In recent
decades, U.S.-Mexican relations have grown closer through cooperative management of the
2,000-mile border, the North American Free Trade Agreement (NAFTA), and security and rule of
law cooperation under the Mérida Initiative. Relations have been tested, however, by President
Donald J. Trump’s shifts in U.S. immigration and trade policies.
President Enrique Peña Nieto of the Institutional Revolutionary Party (PRI) is in the final months
of his six-year term. During 2013, Peña Nieto shepherded significant structural reforms through
the Mexican congress, including a reform that opened Mexico’s energy market to foreign
investment. Nevertheless, he became embroiled in corruption scandals and struggled to address
human rights abuses and insecurity. Homicides surpassed record levels in 2017, hurting his
already relatively low approval ratings. With Peña Nieto’s presidency ending, his government
aims to conclude a revised trade agreement with the Trump Administration before leaving office.
Political attention in Mexico is on the incoming government of Andrés Manuel López Obrador,
the populist leader of the National Regeneration Movement (MORENA) party, who won 53% of
the vote in the July 1, 2018, presidential elections. MORENA’s coalition also won majorities in
both chambers of the legislature that convened on September 1, 2018. López Obrador is a former
mayor of Mexico City who ran for president in 2006 and 2012. He promised to govern differently
than recent PRI and National Action Party (PAN) administrations, which have presided over
periods of moderate economic growth, rising insecurity, and ongoing corruption. Some observers
are concerned that López Obrador could alter Mexico’s investor-friendly policies, but others
predict he will govern responsibly, albeit with a more centralized, state-led development
approach.
U.S. Policy
U.S.-Mexican relations remain relatively strong, but periodic tensions have emerged during the
Trump Administration. In January 2017, President Trump’s assertion that Mexico should pay for
a border wall that it has consistently opposed led Peña Nieto to cancel a White House visit. The
Mexican government continues to oppose paying for the border wall, and it has spoken out
against U.S. “zero tolerance” immigration policies and is concerned about the future of the
Deferred Action for Childhood Arrivals (DACA) initiative. However, bilateral security and
migration management efforts continue. The Trump Administration requested $76.3 million for
the Mérida Initiative for FY2019 (a 35% decline from the FY2017 enacted level). Mexico has
applied retaliatory tariffs in response to recent U.S. tariffs on steel and aluminum imports. In
NAFTA negotiations, the United States and Mexico reached a preliminary agreement in late
August 2018. On September 30, 2018, Canada joined Mexico and the United States in
announcing a new U.S.-Mexico-Canada (USMCA) free trade agreement.
Legislative Action
The 115th Congress has considered legislation affecting Mexico. The Senate passed a resolution
(S.Res. 83) calling for U.S. support for Mexico’s efforts to combat fentanyl. The House approved
a resolution reiterating the importance of bilateral cooperation (H.Res. 336). In March 2018,
Congress provided $152.6 million for Mexico in the FY2018 Consolidated Appropriations Act
(P.L. 115-141), including $145 million for the Mérida Initiative. The House Appropriations
Committee’s FY2019 version of the State Department and Foreign Operations appropriations bill,
H.R. 6385 (H.Rept. 115-829), recommends providing $125 million for Mexico. The Senate
version of the bill, S. 3108 (S.Rept. 115-282) recommends $169.5 million. In September 2018,
the House Foreign Affairs Committee passed a measure (H.R. 1567) to promote U.S.-Mexican

Introduction
Congress has maintained 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, familial, and historical
ties (see Figure 1). Economically, the United States and Mexico are interdependent, and U.S.
policymakers are closely following ongoing efforts to renegotiate the North America Free Trade
Agreement (NAFTA).1 Similarly, security conditions in Mexico affect U.S. national security,
particularly along the U.S.-Mexican border. Observers are concerned about resurgent organized
crime-related violence in Mexico, which reached record levels in 2017 (see Figure 2).2
Mexican President Enrique Peña Nieto is in the final months of his six-year term. In 2013, Peña
Nieto shepherded structural reforms through the Mexican congress by forming an agreement
among his Institutional Revolutionary Party (PRI), the conservative National Action Party (PAN),
and the leftist Party of the Democratic Revolution (PRD) (see Table A-1 in Appendix). Peña
Nieto’s approval rating has remained relatively low since 2014, as his government has struggled
to solve high-profile human rights cases, become embroiled in corruption scandals, and faced
security challenges. Economic growth has averaged 2% annually, but has been hindered by
uncertainty over the future of NAFTA.
The results of the July 1, 2018, presidential and legislative elections could significantly impact
Mexico’s political and economic trajectory, as well as its posture toward the United States.
Discontent with the PRI and voters’ desire for change led them to elect populist Andrés Manuel
López Obrador president with 53% of the vote (see “July 1, 2018, Elections”). Although some
fear that López Obrador, whose National Regeneration Movement (MORENA) coalition also
captured legislative majorities in both chambers of the congress, will reverse Mexico’s reforms
and damage U.S. relations, others predict he will govern pragmatically. President-elect López
Obrador is scheduled to be inaugurated on December 1, 2018 (see “The Incoming López Obrador
Administration”
).
This report provides an overview of political and economic conditions in Mexico, followed by
assessments of selected issues of congressional interest in Mexico: security and foreign aid,
extraditions, human rights, trade, migration, energy, education, environment, and water issues.
Political Situation
Over the past two decades, Mexico has transitioned from a centralized political system dominated
by the PRI to a true multiparty democracy. Since the 1990s, presidential power has become more
balanced with that of Mexico’s Congress and Supreme Court. Partially as a result of these new
constraints on executive power, the country’s first two presidents from the PAN—Vicente Fox
(2000-2006) and Felipe Calderón (2006-2012)—struggled to enact some of the reforms designed
to address Mexico’s economic and security challenges.

The Calderón government pursued an aggressive anticrime strategy and increased security
cooperation with the United States. Mexico arrested and extradited many drug kingpins, but some
60,000 people died due to organized crime-related violence. Mexico’s security challenges
overshadowed some of the government’s achievements, including its economic stewardship
during the global financial crisis, health care expansion, and efforts on climate change.
Twelve years after losing the presidency for the first time in 71 years, the PRI candidate Enrique
Peña Nieto won the 2012 presidential election over López Obrador of the leftist PRD. López
Obrador subsequently left the PRD and founded the MORENA party. In 2012, voters viewed the

PRI as best equipped to reduce violence and hasten economic growth, despite concerns about its
reputation for corruption. Enrique Peña Nieto took office with his party controlling 20 of 32
governorships, but his PRI/Green Ecological Party (PVEM) coalition lacked a legislative
majority. The PRI/PVEM’s control over the legislature further declined after midterm elections
held in 2015.
Structural Reforms: Enacted but Implemented Unevenly
In 2013, President Peña Nieto shepherded structural reforms through a fragmented legislature by
forming a “Pact for Mexico” agreement among the PRI, PAN, and PRD. The reforms addressed a
range of issues, including education, telecommunications, access to finance, and politics (see
Table A-1 in Appendix). Constitutional reforms on energy opened Mexico’s oil, natural gas, and
power sectors to private investment for the first time in more than 70 years but led to the collapse
of the pact in late 2014, due to the PRD’s opposition to the energy reform. Oil and gas companies
have committed to contracts estimated to bring $160 billion in investment into the country.3
Many analysts praised President Peña Nieto and his advisers for shepherding structural reforms
through the Mexican congress but predicted that the reforms’ impact would depend on their
implementation. Mexico’s ranking in the World Economic Forum’s Global Competiveness Index
for 2017 improved, in part due to some of the reforms. Nevertheless, critics have alleged that
votes in favor of the reforms “were duly purchased” by the PRI.”4
Some of Mexico’s reforms have faced problems due to issues in implementation; others have
faced opposition from entrenched interest groups. Still others have faced unfavorable global
conditions.5 Fiscal reforms faced challenges in tax collection, and a 2017 Supreme Court ruling
reportedly watered down the telecommunications reform.6 Teachers unions, particularly in
southern Mexico, vehemently opposed education reforms requiring teacher evaluations and
accountability measures. In June 2016, 8 people died and more than 100 were injured after unions
and police clashed in Oaxaca. Although Mexico’s energy sector has attracted significant
international investment, low global oil prices thus far have rendered shale resources and other
unconventional fields unfeasible to develop.
MORENA has promised to roll back some of the 2013-2014 reforms. The legislature is
considering various proposals to amend or roll back the education reform.7 President-elect López
Obrador has said that although he will respect existing oil contracts, he may halt oil auctions for
two years, prompting some concerns among investors.8
Security Setbacks
President Peña Nieto campaigned on a promise to reduce violence in Mexico. However, six years
later, insecurity has risen sharply (see Figure 2). Organized crime-related homicides in Mexico

rose slightly in 2015 and significantly in 2016. In 2017, total homicides and organized crime-
related homicides reached record levels.9 Homicides in 2018 have continued at extremely
elevated levels.10 The State Department has warned Americans not to travel to five of Mexico’s
32 states and to reconsider whether to travel to another 11 states.11 During Mexico’s 2018
campaign, more than 150 politicians reportedly were killed.12
Infighting among criminal groups has intensified since the rise of the Jalisco New Generation, or
CJNG, cartel, a group that shot down a police helicopter in September 2016. The January 2017
extradition of Joaquín “El Chapo” Guzmán has prompted succession battles within Sinaloa and
emboldened the CJNG and other groups to challenge Sinaloa’s dominance. Crime groups are
competing to supply surging U.S. demand for heroin and other opioids. Mexico’s criminal
organizations also are fragmenting and diversifying away from drug trafficking, furthering their
expansion into activities such as oil theft, alien smuggling, kidnapping, and human trafficking.
Although much of the crime—particularly extortion—disproportionately affects localities and
small businesses, fuel theft has become a national security threat, costing Mexico as much as $1
billion a year and fueling violent conflicts between the army and suspected thieves.13

judge to an adversarial system with oral arguments and the presumption of innocence. During the
new system’s first year in operation, 15% of indictments occurred because of a police
investigation; the rest occurred when the perpetrator was caught in the act of committing a crime
(such as possessing drugs).15 Botched investigations have resulted in judges releasing thousands
of prisoners from prison; citizens have subsequently blamed the new justice system for rising
criminality.16 In addition to these problems in the criminal justice sector, the Peña Nieto
government stopped funding its national prevention program in 2017 and made little headway in
replacing military forces engaged in public security with a national gendarmerie (police).17
Criticism of Peña Nieto’s security strategy has mounted since 2014. Many observers assert that
Peña Nieto has maintained Calderón’s reactive approach of deploying federal forces—including
the military—to areas in which crime surges rather than proactively strengthening institutions to
deter crime and violence.18 In December 2017, the government enacted an internal security law to
provide legal authority for continued military deployments despite harsh criticism from domestic
and international human rights groups, the U.N., and others.19 The Supreme Court is considering
various challenges to its constitutionality.
High-value targeting of top criminal leaders has continued. Security forces had killed or detained
at least 110 of 122 high-value targets identified by the government as of August 2018; only nine
of those individuals received sentences.20 That figure included “El Chapo” Guzmán, recaptured in
January 2016 after escaping from prison in July 2015. High-value targeting has contributed to
crime groups splintering and diversifying their illicit activities, but it has remained a focus of this
government. In August 2018, the Mexican government and the U.S. Drug Enforcement
Administration (DEA) announced a new bilateral effort to arrest the leader of the CJNG.21 Even
as many groups have developed into multifaceted illicit enterprises, government efforts to seize
criminal assets have been modest ($36 million in 2016) and attempts to prosecute money
laundering cases have had “significant shortcomings.”22

of serious human rights violations. The vast majority of those abuses have gone unpunished.23
Incidents such as the forced abduction and killing of 43 students in Iguala, Guerrero, in
September 2014 have galvanized protests against impunity in Mexico. On average, fewer than
20% of homicides have been successfully prosecuted, suggesting high levels of impunity.24
Extrajudicial Killings, Torture, and Enforced Disappearances
For years, human rights groups and U.S. State Department reports have chronicled cases of Mexican security
officials’ involvement in extrajudicial killings, torture, and enforced disappearances.25
Tlatlaya, State of Mexico. In October 2014, Mexico’s National Human Rights Commission (CNDH) issued a
report concluding that the Mexican military killed at least 15 people in Tlatlaya on July 1, 2014. The military
originally claimed that the victims were criminals killed in a confrontation. The CNDH also documented claims of
the torture of witnesses to the killings by state officials. The last three soldiers in custody for killing eight people
that day have been released, but four state prosecutors were convicted of torture. Concerns about the adequacy
of the attorney general’s investigation into the case prompted a federal judge to order it reopened in May 2018.26
Iguala, Guerrero. The unresolved case of 43 missing students who disappeared in Iguala, Guerrero, in
September 2014—which allegedly involved the local police and authorities—galvanized global protests. The
government’s investigation has been widely criticized, and experts from the Inter-American Commission on
Human Rights (IACHR) disproved much of its findings. The government worked with those experts to
reinvestigate the case in 2015-April 2016 but denied their requests to interview soldiers who were in the area of
the incident. In July 2016, the government formed a follow-up mechanism with the IACHR to help ensure follow
up on the experts’ lines of investigation, but it made little progress. In May 2018, a federal judge ruled that the
attorney general’s investigation had not been “impartial or independent” and called for the creation of a creation
of a truth commission to take over the case.27 President-elect López Obrador has said that he will establish a
commission to investigate the case.28
In 2017, 12 journalists died in Mexico, making Mexico the world’s most violent country for
journalists outside a war zone.29 Thus far in 2018, more than 10 journalists have been killed.30
Some 75% of journalists surveyed by Freedom House do not have faith in the mechanism created
to protect them.31 The budget for that mechanism, which currently provides protective measures
for 727 journalists and human rights defenders, has been cut, despite rising demand.32 That figure
is likely even higher now that news outlets have reported that the Peña Nieto government has
used spyware to monitor its critics, including journalists. The government acknowledged
purchasing the spyware but denied using it for espionage.33

Mexico: Background and U.S. Relations

In response to criticism of the aforementioned human rights incidents, President Peña Nieto
proposed 10 actions to improve the rule of law in late 2014. Proposals that have advanced include
launching a national 911 emergency line, reforming the national anticorruption system, and
enacting laws against torture (in April 2017) and enforced disappearances (in October 2017).34
Additional policy changes, including police reforms, were not implemented. Many say a botched
police operation in November 2017 that resulted in the killing of four women and two children in
Temixco, Mexico, illustrates the violent tactics that are still used.35
Corruption and Impunity
Although President Peña Nieto’s proposals focused on confronting corruption at the municipal
level, corruption is a major issue at the state and federal levels. At least fourteen current or former
governors are under investigation for corruption, including collusion with organized crime groups
that resulted in violent deaths and serious human rights violations that have gone unpunished.36
Observers have criticized the federal attorney general’s recent conviction of Javier Duarte, the
former PRI governor of Veracruz who allegedly stole billions of dollars in public funds, as too
lenient (Duarte received a nine-year sentence).37 A government auditor cleared President Peña
Nieto, his wife, and his foreign minister of misconduct, but reports that surfaced in 2014 of how
they benefitted from ties to a firm that won many government contracts tarnished their image. A
credible case against the chair of Peña Nieto’s 2012 campaign (and former head of state oil
company Pemex) for receiving $10.5 million in bribes from Odebrecht, a Brazilian construction
firm, stalled after the prosecutor investigating the case was fired.38
In July 2016, Mexico’s Congress approved legislation to fully implement the national
anticorruption system (NAS) created by a constitutional reform in April 2015. The legislation
reflected several of the proposals put forth by Mexican civil society groups. It gave the NAS
investigative and prosecutorial powers and a civilian board of directors; increased administrative
and criminal penalties for corruption; and required three declarations (taxes, assets, and conflicts
of interest) from public officials and contractors.39 Members of the anticorruption board maintain
that the government has been “thwarting” its efforts by denying requests for information and
failing to appoint an anticorruption prosecutor and judges to hear corruption cases.40

June 22, 2017.
34 According to the U.N., enforced disappearances occur when “persons are arrested, detained or abducted against their
will or otherwise deprived of their liberty by officials of different branches or levels of Government, or by organized
groups or private individuals acting on behalf of, or with the support, direct or indirect, consent or acquiescence of the
Government.” See http://www.un.org/en/events/disappearancesday/background.shtml.

Mexico: Background and U.S. Relations

Mexico’s federal attorney general’s office generally has been incapable of resolving high-profile
cases, including human rights abuses allegedly committed by security forces.41 Since 2015,
federal prosecutors have secured only one federal conviction for corruption.42 Three attorneys
general have resigned in five years. Civil society groups therefore have focused their efforts on
urging President Peña Nieto and the Mexican congress to create an independent national
prosecutor’s office to replace the attorney general’s office, which is dependent on the President,
and to name a respected independent person to lead the new institution.43 President-elect López
Obrador has said that the MORENA-led legislature will appoint an attorney general, as well as an
anti-corruption prosecutor, before he takes office.44
Foreign Policy
President Peña Nieto has prioritized promoting trade and investment in Mexico as a core goal of
his Administration’s foreign policy. During his term, Mexico has begun to participate in U.N.
peacekeeping efforts and to speak out in the Organization of American States on the deterioration
of democracy in Venezuela, a departure for a country with a history of nonintervention. Peña
Nieto has sought to create closer trade ties with Europe, Asia, and the rest of Latin America; these
efforts could become more important should Mexican-U.S. trade decline. He has hosted Chinese
Premier Xi Jinping for a state visit to Mexico, visited China twice, and in September 2017
described the relationship as a “comprehensive strategic partnership.”45
The Peña Nieto government negotiated and signed the proposed Trans-Pacific Partnership (TPP)
trade agreement with other Asia-Pacific countries (and the United States and Canada). Even after
President Trump withdrew the United States from the TPP agreement, Mexico and the 10 other
signatories of the TPP moved forward and concluded their own trade agreement, the
Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). Mexico has
prioritized economic integration efforts with the pro-trade Pacific Alliance countries of Chile,
Colombia, and Peru and focused on expanding markets for those governments.46 Mexico is close
to concluding a modernization of a free-trade agreement (FTA) with the European Union and may
seek a FTA with the United Kingdom. Mexico currently has 11 FTAs involving 46 countries.47
Relations with Canada have improved since 2016, when Prime Minister Justin Trudeau removed
a visa requirement for Mexicans visiting Canada and Mexico lifted a ban on Canadian beef
imports.
Mexico is investing in Central American energy integration projects and supporting the “northern
triangle” (Guatemala, El Salvador, and Honduras) governments’ “Alliance for Prosperity”
proposal to promote development. The Mexican and U.S. governments cohosted a conference on
growth and investment in security in Central America in June 2017.

Mexico: Background and U.S. Relations

July 1, 2018, Elections48
On July 1, 2018, Andrés Manuel López Obrador and his MORENA coalition dominated Mexico’s
presidential and legislative elections. MORENA, a leftist party, ran in coalition with the socially
conservative Social Encounter Party (PES) and the leftist Labor Party (PT). López Obrador won
53.2% of the presidential vote, more than 30 percentage points ahead of his nearest rival, Ricardo
Anaya, of the PAN/PRD/Citizen’s Movement (MC) alliance (See Figure 3 below).
Figure 3. 2018 Presidential Election Results

Source: Mexico’s National Electoral Institute (INE)
López Obrador is a 64-year-old former mayor of Mexico City (2000-2005) who ran for president
in the past two elections. After his loss in 2012, he left the center-left Democratic Revolutionary
Party (PRD) and established MORENA. Although some of his advisers endorse progressive
social policies, López Obrador reportedly personally opposes abortion and gay marriage.49 In
2018, López Obrador promised to bring about change by governing differently than recent PRI
and PAN administrations. He focused on addressing voters’ concerns about corruption, poverty,
inequality, and escalating crime and violence.
The presidential election results have prompted soul-searching within the traditional parties and
shown the limits of independent candidates. Anaya’s defeat has provoked internal struggles
within the PAN. Meade’s poor performance has similarly demonstrated voters’ deep frustration
with the PRI; the PVEM has since abandoned its alliance with the party. The PAN and the PRI
each will still likely control 12 governorships (a recount is under way in Puebla to verify a PAN
victory in that state), but MORENA won 5 governorships (including in Mexico City) and the MC
won 1. One of the other two governors is from the PVEM; the other is an independent
(Rodríguez).

Mexico: Background and U.S. Relations

In addition to the presidential contest, all 128 seats in the Mexican senate and 500 seats in the
chamber of deputies were up for election. Senators serve for six years, and deputies serve for
three. Beginning this cycle, both senators and deputies will be eligible to run for reelection for a
maximum of 12 years in office.
MORENA’s coalition won majorities in the Senate (69 of 128 seats) and the Chamber (308 of
500 seats), which convened on September 1, 2018. In the Chamber, the PVEM ceded five seats to
MORENA, giving the ruling coalition 313 seats, close to a two-thirds majority.50 The MORENA
coalition lacks the two-thirds majority it needs to make constitutional changes or overturn
reforms passed in 2013. It may be able to form alliances with the center-left PRD or others on
specific issues, however. The PAN is the second-largest party in each chamber.
The Incoming López Obrador Administration
Mexican voters gave President-elect López Obrador a mandate to change the course of Mexico’s
domestic politics, but he will face constraints in enacting his agenda, including from governors
from opposition parties who have spoken out against his proposals to expand federal power.51
López Obrador has set high expectations for his government and promised many things to many
different constituencies, some of which appear to conflict with each other. As an example, he has
promised to govern austerely but has proposed a number of new social programs.52 His future
finance minister, U.S.-trained economist Carlos Urzua, has said that the incoming government
will respect existing oil contracts, while his energy minister, Rocio Nahle (a chemical engineer
and former MORENA legislator), has been an opponent of private involvement in the industry.53
Some of his security proposals that may prompt concern among some U.S. officials, such as
seeking to decriminalize marijuana and potentially opium production, have been put forth by his
chosen interior minister, Olga Sánchez Cordero, a former supreme court justice.54
López Obrador has proposed the following key domestic goals:
 Increasing prison sentences and prohibiting bail for those accused of corruption
and electoral crimes;
 Implementing an austerity plan to cut high-level government officials’ salaries
and benefits;
 Placing one federal representative in each state to handle all disbursements of
federal funding from all agencies and liaise with the presidency;
 Establishing a universal pension for the elderly;
 Combating root causes of insecurity by giving youth stipends to study or
complete internships, enacting a transitional justice law that may reduce prison
time for nonviolent offenders, and revising drug policy;

 Reviewing all energy contracts for irregularities and bolstering Mexico’s refining
capacity;
 Modifying or repealing the 2013 education reforms; and
 Boosting expenditures on infrastructure and revitalizing the domestic agricultural
sector.55
In the area of foreign policy, President-elect López Obrador generally has maintained that the
best foreign policy is a strong domestic policy. His future foreign minister, Marcelo Ebrard
(former mayor of Mexico City), has said that a López Obrador government is likely to return to
Mexico’s traditional, non-interventionist approach to foreign policy (the so-called Estrada
doctrine). As an example, Ebrard predicted that Mexico could scale back the role it has played in
seeking to address the crises in Venezuela.56 Many analysts predict that Mexico would continue to
engage on global issues that it deems important, however, such as climate change.
President-elect López Obrador’s position on trade policy and NAFTA, which he formerly
criticized for hurting Mexico’s agricultural sector, have evolved. His chief NAFTA negotiator,
Jesús Seade (a former World Trade Organization official) and future minister of the economy,
Graciela Márquez (an academic and economist) had suggested that the incoming government
would accept an agreement negotiated by the outgoing administration. President-elect López
Obrador reportedly urged the United States and Canada to resolve outstanding disputes to reach a
revised trilateral agreement.57 The government also is likely to continue participating in pro-trade
fora, such as the Pacific Alliance, and seeking to diversify its export partners to reduce its reliance
on the United States. It likely will have to balance support for NAFTA, which has benefitted
northern and central Mexico, with promises to develop southern Mexico and revitalize
agricultural sectors hurt by NAFTA.58
Economic and Social Conditions59
Mexico has transitioned from a closed, state-led economy to an open market economy that, as
mentioned, has entered into free trade agreements with 46 countries. The transition began in the
late 1980s and accelerated after Mexico entered into NAFTA in 1994. Since NAFTA, Mexico has
increasingly become an export-oriented economy, with the value of exports equaling more than
38% of Mexico’s gross domestic product (GDP) in 2016, up from 10% of GDP 20 years ago.
Mexico remains a U.S. crude oil supplier, but its top exports to the United States are automobiles
and auto parts, computer equipment, and other manufactured goods. One report estimates that
40% of the content of those exports contain U.S. value added content.60

Despite attempts to diversify its economic ties and build its domestic economy, Mexico remains
heavily dependent on the United States as an export market (roughly 80% of Mexico’s exports in
2017 were U.S.-bound) and as a source of remittances, tourism revenues, and investment. Studies
estimate that a U.S. withdrawal from NAFTA, could cost Mexico more than 950,000 low-skilled
jobs and lower its GDP growth by 0.9%.61 In recent years, remittances have replaced oil exports
as Mexico’s largest source of foreign exchange. According to Mexico’s central bank, remittances
reached a record $28.8 billion in 2017. In contrast, U.S. travel warnings about security conditions
in Mexico contributed to a decline in U.S. tourism arrivals to Mexico.62 Although it has regained
value since the July elections, a weakened peso helped Mexico’s overall tourism industry and
some export industries in 2017, but the uncertainty that has contributed to its decline in value
against the dollar has weakened foreign direct investment.63
The Mexican economy grew by roughly 2% in 2017 and growth may reach 2.3% in 2018,
buoyed, in part, by reconstruction following earthquakes that occurred in September 2017.64 In
addition to concerns about the future of NAFTA, analysts warn that growth could decline if
corporations choose to invest more in the United States than in Mexico due to the new U.S.
corporate tax rate of 21% (Mexico’s corporate rate is 30%).65 Some observers believe that
investor sentiment and the country’s growth prospects also could worsen if President-elect López
Obrador rolls back recent structural reforms, increases the country’s debt burden, or promotes
government intervention in the economy.66
Economic conditions in Mexico tend to follow economic patterns in the United States. When the
U.S. economy is expanding, as it is now, the Mexican economy tends to grow. However, when the
U.S. economy stagnates or contracts, the Mexican economy also tends to contract, often to a
greater degree. Sound macroeconomic policies, a strong banking system, and recent structural
reforms backed by a flexible line of credit with the International Monetary Fund (IMF) have
helped Mexico weather recent economic volatility.67 Nevertheless, the IMF has recommended
additional steps to deal with potential external shocks. These steps include improving tax
collection, reducing informality, reforming public administration, and improving governance.
Factors Affecting Economic Growth
Over the past 30 years, Mexico has recorded a somewhat low average economic growth rate of
2.6%. Some factors—such as plentiful natural resources, a young labor force, and proximity to
markets in the United States—have been counted on to help Mexico’s economy grow faster in the
future. Most economists maintain that those factors could be bolstered over the medium to long
term by continued implementation of some of the reforms described in Table A-1.
At the same time, continued insecurity and corruption, a relatively weak regulatory framework,
and challenges in its education system may hinder Mexico’s future industrial competitiveness.

Mexico: Background and U.S. Relations

Corruption costs Mexico as much as $53 billion a year (5% of GDP).68 A lack of transparency in
government spending and procurement, as well as confusing regulations and red tape, has likely
discouraged some investment. Deficiencies in the education system, including a lack of access to
vocational education, have led to firms having difficulty finding skilled labor.69
Another factor affecting the economy is the price of oil. Because oil revenues make up a large, if
lessening, part of the country’s budget, low oil prices since 2014 have required budget cutbacks.
The 2017 budget cut funding for all ministries, including the ministries of transport and
education, which impact the businesses climate.70 The government also has raised other taxes to
recoup lost revenue from oil.
Many analysts predict that Mexico will have to combine efforts to implement its economic
reforms with other actions to boost growth. A 2017 report by the Organisation for Economic Co-
operation and Development suggests that Mexico will need to enact complementary reforms to
address issues such as corruption, weak governance, and lack of judicial enforcement to achieve
its full economic growth potential.71
Combating Poverty and Inequality
Mexico has long had relatively high poverty rates for its level of economic development (43.6%
in 2016), particularly in rural regions in southern Mexico and among indigenous populations.72
Some assert that conditions in indigenous communities have not measurably improved since the
Zapatistas launched an uprising for indigenous rights in 1994.73 Traditionally, those employed in
subsistence agriculture or small, informal businesses tend to be among the poorest citizens. Many
households rely on remittances to pay for food, clothing, health care, and other basic necessities.
Mexico also experiences relatively high income inequality. According to the 2014 Global Wealth
Report
published by Credit Suisse, 64% of Mexico’s wealth is concentrated in 10% of the
population. Mexico is among the 25 most unequal countries in the world included in the
Standardized World Income Inequality Database. According to a 2015 report by Oxfam Mexico,
this inequality is due in part to the country’s regressive tax system, oligopolies that dominate
particular industries, a low minimum wage, and a lack of targeting in some social programs.74
Economists have maintained that reducing informality is crucial for addressing income inequality
and poverty, while also expanding Mexico’s low tax base. The 2013-2014 reforms sought to
boost formal-sector employment and productivity, particularly among the small- and medium-
sized enterprises (SMEs) that employ some 60% of Mexican workers, mostly in the informal
sector. Although productivity in Mexico’s large companies (many of which produce
internationally traded goods) increased by 5.8% per year between 1999 and 2009, productivity in
small businesses fell by 6.5% per year over the same period.75 To address that discrepancy, the

financial reform aimed to increase access to credit for SMEs and the fiscal reform sought to
incentivize SMEs’ participation in the formal (tax-paying) economy by offering insurance,
retirement savings accounts, and home loans to those that register with the national tax agency.
The Peña Nieto Administration has sought to complement economic reforms with social
programs and, more recently, with the establishment of special economic zones (ZEEs) with low
taxes and other investment incentives in the south of Mexico.76 It expanded access to federal
pensions, started a national anti-hunger program, and increased funding for the country’s
conditional cash transfer program.77 Peña Nieto renamed that program Prospera (Prosperity) and
redesigned it to encourage its beneficiaries to engage in productive projects. Despite recent
budget austerity, funding for these programs has been largely protected, but some programs have
been criticized for a lack of efficacy.78
U.S. Relations and Issues for Congress
Mexican-U.S. relations generally have grown closer over the past two decades. Common interests
in encouraging trade flows and energy production, combating illicit flows (of people, weapons,
drugs, and currency), and managing environmental resources have been cultivated over many
years. A range of bilateral talks, mechanisms, and institutions have helped the Mexican and U.S.
federal governments—as well as stakeholders in border states, the private sector, and
nongovernmental organizations—find common ground on difficult issues, such as migration and
water management. U.S. policy changes that run counter to Mexican interests in one of those
areas could trigger responses from the Mexican government on other areas where the United
States benefits from Mexico’s cooperation, such as combating illegal migration.79
President Trump’s shifts in U.S. immigration policies have tested U.S.-Mexican relations. His
repeated assertions that Mexico will pay for a border wall resulted in President Peña Nieto
canceling a White House meeting in January 2017 and have continued to periodically strain
relations.80 The Mexican government expressed regret after the Administration’s decision to
rescind the Deferred Action for Childhood Arrivals (DACA) initiative, which has provided work
authorization and relief from removal for migrants brought to the United States as children, but
pledged to assist DACA beneficiaries who return to Mexico.81 In June 2018, Mexico criticized
U.S. “zero tolerance” immigration policies.82 Despite these developments, Mexico has continued
to work with the United States on migration management and border issues.

The Trump Administration has made NAFTA renegotiation a prominent priority of its trade
policy, but it also has imposed tariffs on major trade partners (including Canada and Mexico) on
grounds that imports of products such as steel and aluminum harm U.S. national security.83 After
a year of talks among the NAFTA partners, the Administration notified Congress of President
Trump’s intent to “sign a trade agreement with Mexico- and Canada, if it is willing” on August
31, 2018.84 That notification, required under Trade Promotion Authority (TPA) governing
expedited congressional consideration of trade agreements, is intended to permit the signing of a
trade agreement before Mexico’s change in government is scheduled to take place on December
1, 2018.85 On September 30, 2018, the United States Trade Representative (USTR) announced
that Canada and the United States had resolved pending differences and that the three
governments would sign a revised agreement, the U.S.-Mexico-Canada agreement. 86
State Department Assistance87
U.S.-Mexican cooperation to improve security and the rule of law in Mexico has increased due to
the development and implementation of the Mérida Initiative, a program developed by the George
W. Bush and Felipe Calderón (2006-2012) governments. As proposed, the Mérida Initiative was
to provide some $1.4 billion in counterdrug and anticrime assistance to Mexico and Central
America, largely in the form of equipment and training for security forces, from FY2008 through
FY2010.88 Although total U.S. appropriations for the Mérida Initiative (nearly $2.9 billion) thus
far constitute only 2% of Mexico’s total security budget of $10 billion per year, they have enabled
the U.S. government to help shape Mexico’s security policy.
In 2011, the U.S. and Mexican governments agreed to broaden the scope of bilateral efforts to
focus on four pillars: (1) disrupting organized criminal groups, (2) institutionalizing the rule of
law, (3) creating a 21st-century border, and (4) building strong and resilient communities. From
FY2012 to FY2017, funding for pillar two—building the rule of law—exceeded funds for all
other pillars and military assistance no longer formed a part of the Mérida Initiative. Although
some analysts praised the wide-ranging cooperation between the governments, others criticized
the increasing number of priorities included in the Mérida Initiative.
President Trump’s executive orders on combatting transnational criminal organizations (TCOs;
E.O. 13773) and enhancing border security (E.O. 13767) have refocused the Mérida Initiative.
Trump Administration officials have held three Cabinet-level dialogues on security with the
outgoing Mexican government focused on attacking the TCOs’ business model. As a result,

recent Mérida Initiative programs have focused on combating the production and distribution of
opioids and other drugs, improving border interdiction and port security, training forensic experts
to gather evidence and testify in criminal trials, and combating money laundering.89 The
Administration asked for $76.3 million in its FY2019 budget request for the Mérida Initiative:
$56 million in International Narcotics Control and Law Enforcement (INCLE) funding to combat
crime groups, improve drug interdiction, and train Mexican law enforcement and judicial
personal and $20.3 million in Economic Support Funds (ESF) to strengthen the rule of law,
combat corruption, bolster human rights, and prevent crime. Future budget requests are likely to
reflect priorities agreed upon after negotiations with the incoming López Obrador government in

Notes: ESF = Economic Support Fund; INCLE = International Narcotics Control and Law Enforcement; FMF =
Foreign Military Financing. FY2008-FY2010 included supplemental funding.
a. For FY2017, Mérida programs administered by the U.S. Agency for International Development (USAID)
were funded through the Development Assistance account rather than ESF.
b. In the FY2019 budget request, the Trump Administration proposes a new aid account to merge the
Economic Support and Development Fund accounts. It is to be known as the Economic Support and
Development Fund account, or ESDF.
Although budget requests for the Mérida Initiative have been declining, there has been bipartisan
support in Congress for sustaining level funding for the initiative (see Table 1). The House and
Senate Appropriations Committees have approved their respective FY2019 State Department,
Foreign Operations, and Related Programs appropriations measures. H.Rept. 115-829 to the
House committee bill (H.R. 6385) recommends providing $120 million in INCLE for Mexico; it
does not specify an ESF amount. S.Rept. 115-282 to the Senate committee bill (S. 3108 )
recommends providing $163 million ($100 million in INCLE and $63 million in ESF).
Department of Defense Assistance
In contrast to Plan Colombia, the Department of Defense (DOD) did not play a primary role in
designing the Mérida Initiative and is not providing assistance through Mérida accounts.
However, DOD oversaw the procurement and delivery of equipment provided through the FMF
account. Despite DOD’s limited role in the Mérida Initiative, bilateral military cooperation has
been increasing. DOD assistance aims to support Mexico’s efforts to improve security in high-
crime areas, track and capture suspects, strengthen border security, and disrupt illicit flows.
A variety of funding streams support DOD training and equipment programs. Some DOD
equipment programs are funded by annual State Department appropriations for FMF, which
totaled $5.0 million in FY2018. International Military Education and Training (IMET) funds,
which totaled $1.5 million in FY2018, support training programs for the Mexican military,
including courses in the United States. Apart from State Department funding, DOD provides
additional training, equipping, and other support to Mexico that complements the Mérida
Initiative through its own accounts. Individuals and units receiving DOD support are vetted for
potential human rights issues in compliance with the Leahy Law. DOD programs in Mexico are
overseen by U.S. Northern Command, which is located at Peterson Air Force Base in Colorado.
DOD counternarcotics support to Mexico totaled approximately $63.3 million in FY2018.
Policymakers may want to receive periodic briefings on DOD efforts to guarantee that DOD
programs are being adequately coordinated with Mérida Initiative efforts, complying with U.S.
vetting requirements, and not reinforcing the militarization of public security in Mexico.
Extraditions
During the Calderón government, extraditions were another indicator that the State Department
used as an example of the Mérida Initiative’s success. During the final years of the Calderón
government, Mexico extradited an average of 98 people per year to the United States, an increase
over the prior Administration. When President Peña Nieto took office, extraditions fell to 54 in
2013 but rose to a high of 79 in 2016 (see Figure 4, below).

Human Rights91
The U.S. Congress has expressed ongoing concerns about human rights conditions in Mexico.
Congress has continued to monitor 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), which pertains
to State Department aid, and 10 U.S.C. 2249e, which guides DOD funding. DOD reportedly
suspended assistance to a brigade based in Tlatlaya, Mexico, due to concerns about the brigade’s
potential involvement in the extrajudicial killings previously described.92 From FY2008 to
FY2015, Congress made conditional 15% of U.S. assistance to the Mexican military and police
until the State Department sent a report to appropriators verifying that Mexico was taking steps to
comply with certain human rights standards. In FY2014, Mexico lost $5.5 million in funding due
to human rights concerns.93 For FY2016-FY2018, human rights reporting requirements applied to
FMF rather than to Mérida Initiative accounts.94
U.S. assistance to Mexico has supported the Mexican government’s efforts to reform its judicial
system and to improve human rights conditions in the country.95 Congress has provided funding

93 As a result of the State Department’s decision not to submit a report for Mexico, some $5 million in FY2014
International Narcotics Control and Law Enforcement (INCLE) assistance was reprogrammed by the State Department
to Peru. Mexico lost close to $500,000 in Foreign Military Financing (FMF), as well.

to support Mexico’s transition from an inquisitorial justice system to an oral, adversarial, and
accusatory system that aims to strengthen human rights protections for victims and the accused.
The State Department has established a high-level human rights dialogue with Mexico. The U.S.
Agency for International Development (USAID) has supported Mexico’s 2014-2018 human
rights plan, including the development of legislation in compliance with international standards,
prevention efforts, improved state responses to abuses, and expanded assistance to victims.96 One
current project addresses the way the Mexican government addresses cases of torture and
enforced disappearances, whereas others aim to help the government protect journalists and
resolve crimes committed against them.97 In many of these areas, U.S. technical assistance to the
government is complemented by support to think tanks and civil society organizations.
Despite these efforts, the Mexican government continues to be criticized for not investigating and
punishing serious human rights abuses committed by security forces and for not adequately
protecting journalists, migrants, and other vulnerable groups.98 Observers are particularly
concerned about cases of torture, extrajudicial killings, and enforced disappearances, particularly
since the Mexican congress enacted a law in late 2017 to make the military’s involvement in
public security permanent.99 Some urge the U.S. government to stop funding Mexico’s military-
led approach to public security.100 Others recommend increasing U.S. support for judicial and
police reform (particularly accountability and anticorruption programs).101 Many others
recommend working with nongovernmental organizations to strengthen communities’ abilities to
exert oversight over the police and to report human rights abuses.
Congress may choose to augment Mérida Initiative funding for human rights programs, such as
ongoing training programs for military and police, or to fund new efforts to support human rights
organizations. Human rights conditions in Mexico, as well as compliance with conditions
included in the FY2018 Consolidated Appropriations Act (P.L. 115-141), are likely to be closely
monitored.102 Some Members of Congress have written letters to U.S. and Mexican officials
regarding human rights concerns, including allegations of extrajudicial killings by security forces,
abuses of Central American migrants, and the use of spyware against human rights activists.
U.S. policymakers may question how the Peña Nieto Administration is moving to punish past
human rights abusers, how it intends to prevent new abuses from occurring, and how the police
and judicial reforms being implemented are bolstering human rights protections.

97 The United States is supporting Mexican government efforts to protect journalists and bringing together journalists,
media outlet owners, civil society, and the private sector to play a role in monitoring and improving protection and
prosecution efforts. USAID has provided at least $6.6 million to support freedom of expression and protection for
journalists in Mexico, and it plans to invest at least another $4.2 million through September 2019.

Mexico: Background and U.S. Relations

Economic and Trade Relations103
The United States and Mexico have a strong economic and trade relationship that has been
bolstered through NAFTA. Since 1994, NAFTA has removed virtually all tariff and nontariff
trade and investment barriers among partner countries and provided a rules-based mechanism to
govern North American trade. Most economic studies show that the net economic effect of
NAFTA on the United States and Mexico has been relatively small but positive, though there
have been adjustment costs to some sectors in both countries. Further complicating assessments
of NAFTA, not all trade-related job gains and losses since NAFTA entered into force can be
entirely attributed to the agreement. Numerous other factors have affected trade trends, such as
Mexico’s trade-liberalization efforts, economic conditions, and currency fluctuations.
Nevertheless, U.S.-Mexican trade has increased rapidly since NAFTA. The United States is
Mexico’s leading partner in merchandise trade, and Mexico is the United States’ third-largest
trade partner, after China and Canada. Mexico ranks second among U.S. export markets, after
Canada, and is the third-leading supplier of U.S. imports. Total trade (exports plus imports)
amounted to $525.2 billion in 2016 and $368 billion in 2017. Much of the bilateral trade between
the United States and Mexico occurs in the context of supply chains, as manufacturers in each
country work together to create goods. The expansion of trade has resulted in the creation of
vertical supply relationships, especially along the U.S.-Mexican border. The flow of intermediate
inputs produced in the United States and exported to Mexico and the return flow of finished
products increased the importance of the U.S.-Mexican border region as a production site.
Foreign direct investment (FDI) is also an integral part of the bilateral economic relationship. The
stock of U.S. FDI in Mexico increased from $17 billion in 1994 to $87.6 billion in 2016.104
Mexican FDI in the United States is lower than U.S. investment in Mexico but also has increased
in recent years. In 2016, Mexican FDI in the United States totaled $16.8 billion.
The Obama Administration engaged in bilateral efforts with Mexico to balance border security
with facilitating legitimate trade and travel, promote economic competitiveness, and pursue
energy integration. The U.S.-Mexican High-Level Economic Dialogue, launched in 2013, was a
bilateral initiative to advance economic and commercial priorities through annual Cabinet
meetings. The High-Level Regulatory Cooperation Council launched in 2012 helped align
regulatory principles. Trilateral (with Canada) cooperation occurred under the aegis of the North
American Leadership Summits. While those mechanisms have not continued, the bilateral
Executive Steering Committee (ESC), guiding broad efforts along the border and the Bridges and
Border Crossings group on infrastructure have continued to meet.105
Mexico, Canada, and the United States participated in negotiations for the Trans-Pacific
Partnership (TPP) agreement, a proposed FTA with nine other Asia-Pacific countries that was
signed on February 4, 2016.106 On January 23, 2017, President Trump directed the USTR to

representatives from the border states in both countries to discuss infrastructure and other issues.

withdraw the United States as a signatory to the TPP agreement; the acting USTR gave
notification to that effect on January 30, 2017. In November 2017, Mexico and 10 other former
TPP countries agreed to the core elements of a new agreement, the Comprehensive and
Progressive Agreement for Trans-Pacific Partnership (CPTPP) to replace the TPP. Mexico signed
onto the CPTPP in March 2018 and the Mexican senate approved the agreement the following
month.107
Trade Disputes
Despite positive advances on many aspects of bilateral and trilateral economic relations, trade
disputes continue to arise. The United States and Mexico have had a number of trade disputes
over the years, many of which have been resolved. Some of them have involved: country-of-
origin labeling, tomato imports from Mexico, dolphin-safe tuna labeling, and NAFTA trucking
provisions.108 In 2017, Mexico and the United States concluded a suspension agreement on a U.S.
antidumping and countervailing duty investigation on Mexican sugar exports to the United States
in which Mexico agreed to certain limitations on its access to the U.S. sugar market.109 On
January 24, 2018, President Trump announced new tariffs on imported solar panels and washing
machines under the Trade Act of 1974 that would include products coming from Mexico, a move
that Mexico is likely to dispute.110
The Trump Administration has imposed tariffs on U.S. imports of steel and aluminum under
Section 232 of the Trade Expansion Act of 1962, as amended.111 In response, Mexico applied
retaliatory tariffs of 5% to 25% on U.S. exports valued at approximately $3.6 billion on pork,
apples, potatoes, and cheese, among other items. Most of Mexico’s tariffs went into effect on
June 5, 2018, and on July 5, 2018.
On May 23, 2018, the Trump Administration initiated a Section 232 investigation into the imports
of motor vehicles and automotive parts (83 FR 24735) to determine if those imports threaten to
impair U.S. national security.112 Automobiles and parts are important exports for Mexico and
Canada. The Administration may be using the threat of tariffs on these products to create U.S.
leverage for ongoing NAFTA negotiations.
NAFTA Renegotiations and the Preliminary U.S.-Mexico Agreement113
The Trump Administration has made NAFTA renegotiation and modernization a prominent
priority of its trade policy. President Trump has described the agreement as the “worst trade deal”

and has stated that he may seek to withdraw from the agreement, including in September 2018.114
He has focused on the trade deficit with Mexico as a major reason for his critique. On May 18,
2017, the Trump Administration sent a 90-day notification to Congress of its intent to begin talks
to renegotiate NAFTA, as required by the 2015 Trade Promotion Authority (TPA). Negotiations
started August 16, 2017.
This notification and an announcement on August 27, 2018, that the United States and Mexico
had reached a preliminary agreement in principle—subject to finalization and implementation—
served as the culmination of a year of talks among the NAFTA partners. Talks with Canada have
not concluded, and it is unclear whether Congress would support an agreement that does not
include Canada. The United States and Mexico stated that they would like to sign the agreement
before Mexico’s president-elect is scheduled to take office on December 1, 2018. The Mexican
president can submit the agreement to the senate for consideration as soon as it is signed and the
accompanying paperwork required by Mexico’s law on international treaties related to economic
matters is prepared.115
Migration and Border Issues
Mexican-U.S. Immigration Issues
Immigration policy has been a subject of congressional concern over many decades, with much of
the debate focused on how to prevent unauthorized migration and address the large population of
unauthorized migrants living in the United States. Mexico’s status as both the largest source of
migrants in the United States and a continental neighbor means that U.S. migration policies—
including stepped-up border and interior enforcement—have primarily affected Mexicans.116
Beginning in FY2012, foreign nationals from countries other than Mexico began to comprise a
growing percentage of total apprehensions, even as total apprehensions declined to 40-year
lows.117 Due to a number of factors, more Mexicans have been leaving the United States than
arriving.118 Nevertheless, protecting the rights of Mexicans living in the United States, including
those who are unauthorized, remains a top Mexican government priority.
Since the mid-2000s, successive Mexican governments have supported efforts to enact
immigration reform in the United States, while being careful not to appear to be infringing upon
U.S. authority to make and enforce immigration laws. Mexico has made efforts to combat
transmigration by unauthorized migrants and worked with U.S. law enforcement to combat alien
smuggling and human trafficking.119 In FY2017, the Trump Administration removed (deported)

Mexico: Background and U.S. Relations

some 128,765 Mexicans, as compared to 149,821 removals in FY2016.120 During the Obama
Administration, some of Mexico’s past concerns about U.S. removal policies, including nighttime
deportations and issues concerning the use of force by some U.S. Border Patrol officials, were
addressed through bilateral migration talks and letters of agreement.121
Donald Trump made promises of restricting immigration, which he variously described as a threat
to U.S. security and to economic prosperity, a central component of his campaign.122 Within days
of taking office, President Trump signed a series of executive orders on immigration. Of those,
executive orders focused on hastening construction of a border wall (E.O. 13677) and increasing
interior enforcement (E.O. 13678) likely have had the most direct impact on Mexican citizens
living unlawfully in the United States.123 The Trump Administration’s September 2017
announcement to rescind the DACA program beginning in March 2018 barring legislative action
also would disproportionately affect Mexicans (80% of all DACA recipients).124
Congress has considered the amount and type of funding to provide for border infrastructure (e.g.,
what President Trump has described as a border wall). The Trump Administration asked for $1.4
billion in FY2017 supplemental appropriations for U.S. Customs and Border Protection (CBP),
including $1 billion “for planning, design, and construction of the first installment of the border
wall.”125 Congress responded to the request in the FY2017 Consolidated Appropriations Act (P.L.
115-31), which provided a total of $533 million for border assets and infrastructure, including
funding for repairs and upgrades to existing border barriers.126 The Administration asked for some
$1.6 billion for construction of border infrastructure in its FY2018 Department of Homeland
Security budget request. Congress met that request in the FY2018 Consolidated Appropriations
Act (P.L. 115-141). The Administration is seeking $5 billion for border infrastructure in FY2019.
In E.O. 13678, the Trump Administration broadened the categories of authorized immigrants
prioritized for removal. According to the Migration Policy Institute, U.S. Immigration and
Customs Enforcement (ICE) arrested 42% more individuals (including Mexicans) from January
20, 2017, through the end of September 2017 and removed 37% more individuals from the
interior of the United States than in the same period in 2016. Of those arrested, almost 30%
reportedly had no criminal conviction.127 Those trends have since continued, according to ICE
data for FY2017.128 As a result, the profile of Mexican deportees now include more individuals

who have spent many decades in the United States than in recent years (when the Obama
Administration had focused on recent border crossers and those with criminal records).129
The potential for large-scale removal of Mexican nationals present in the United States without
legal status is an ongoing concern of the Mexican government that reportedly has been expressed
to Trump Administration officials.130 Mexico’s consular network in the United States has
bolstered the services offered to Mexicans in the United States, including access to identity
documents and legal counsel.131 It has launched a 24-hour hotline and mobile consultants to
provide support, both practical and psychological, to those who may have experienced abuse or
are facing removal. The Mexican government also criticized U.S. “zero tolerance” immigration
policies implemented in May 2018 that resulted in family separations at the U.S. Southwest
border.132
The Mexican government has expressed hope that the U.S. Congress will develop a solution to
resolve the phased ending of the DACA initiative and has said that it would welcome and provide
support to any DACA enrollees that may be deported.133 As of July 2018, some 561,400
Mexicans brought to the United States as children had received work authorizations and relief
from removal through DACA.134 Many DACA recipients born in Mexico have never visited the
country, and some do not speak Spanish.
Dealing with Unauthorized Migration, Including from Central America135
In 2014, the United States and Mexico experienced a surge in the unauthorized migration of
unaccompanied children and family units from Central America. More recently, increasing
numbers of apprehensions of Central American family units are occurring within the context of
relatively low historical levels of total apprehensions. Since FY2012, the composition of family
unit apprehensions by origin country has shifted from mostly Mexican (80%) to mostly El
Salvadoran, Guatemalan, and Honduran (97%).136 Many of those families are seeking asylum.
In July 2014, Mexico announced a new Southern Border Plan. The plan aimed to increase
security at 12 ports of entry from Guatemala and Belize and along migration routes. It prioritized
(1) regular and ordered migration, (2) infrastructure improvements, (3) protection of migrants, (4)
regional shared responsibilities (including cooperation with Central America), and (5) interagency

132 In May 2018, DOJ implemented a zero tolerance policy toward illegal border crossing. Under the policy, DOJ
prosecuted all adults apprehended while crossing the border illegally, with no exception for asylum seekers or those
with minor children. This policy resulted in up to 3,000 children being separated from their parents. After a federal
judge mandated that all separated children be reunited with their families in late June 2018, DHS reverted to some prior
immigration enforcement policies. For information on those policies, see CRS Report R45266, The Trump

not have a border police. Instead, its National Institute of Migration (INM) is the only agency
with legal authority to detain migrants. These unarmed agents have worked to increase
immigration control along known migration routes, including northbound trains and at bus
stations. INM has improved the infrastructure at border crossings and created mobile highway
checkpoints. With U.S. support (discussed below), INM is seeking to professionalize its
workforce and to improve coordination and communication with the federal police, navy, army,
and customs agencies. Many human rights groups have expressed concerns that the Southern
Border Plan does little to address corruption among police and migration officials and that it has
made migration routes more clandestine and dangerous.
Studies by the U.N. High Commissioner for Human Rights (UNHCR) and others have found that
half of all children and a sizable proportion of women fleeing the northern triangle may need
international protection. Mexico has a broader definition of refugee than the United States.
Migrants’ rights activists have claimed that INM agents inform very few migrants of the right to
request asylum, as required by law, and that asylum, if granted, would enable them to stay in
Mexico permanently. Even with support from UNHCR, Mexico’s Commission for the Aid of
Refugees (COMAR) has insufficient capacity to process claims. COMAR granted refugee status
to 1,426 individuals from northern triangle countries in 2017, up from 880 in 2015.137 The agency
processed 30% of the asylum applications it received in 2017. In July 2018, the Mexican
government announced a 150% budget increase and 84% staffing increase for COMAR.138
The U.S. State Department has allocated more than $100 million in Mérida Initiative funding to
support Mexico’s southern border efforts.139 As of July 2018, the State Department had delivered
$32 million of that assistance, mostly in the form of nonintrusive inspection equipment, mobile
kiosks, canine teams, vehicles, and training. By late 2018, U.S. funds are expected to have helped
build a secure communications network for Mexican agencies in the southern border region. By
2019, U.S. funds aim to help Mexico collect biometric information that can interface with U.S.
databases, at all of its migration stations. It is unclear whether Mexico will accept $20 million
offered by the Trump Administration to pay for removing U.S.-bound migrants.140
In addition to Mérida Initiative funds, the State Department has provided funding through the
Migration and Refugees Assistance foreign aid account to UNHCR to help strengthen Mexico’s
humanitarian protection system. UNHCR estimates that it has used roughly $8.8 million in
unrestricted U.S. funds in FY2016 and $8 million in FY2017 for programs in Mexico.141 These
funds have helped to improve access to asylum, give legal assistance to asylum seekers, provide
alternatives to detention to asylum seekers, and increase the asylum capacity at COMAR. The

measure, S. 3108, stipulates that $18 million of the ESF provided should be “transferred to, and
merged with” funds appropriated under the Migration and Refugees Assistance account to
UNHCR to help process the asylum applications of Central Americans in Mexico.
Mexico has reportedly resisted signing a “safe third country agreement” with the United States,
which could require asylum seekers who transit through Mexico to seek asylum there rather than
in the United States.142 Mexico will not accept non-Mexican nationals who illegally entered the
United States via the U.S.-Mexican land border (as DHS had reportedly proposed).143
Modernizing the U.S.-Mexican Border
Since the terrorist attacks of September 11, 2001, there have been significant delays and
unpredictable wait times at the U.S.-Mexican border.144 The majority of U.S.-Mexican trade
passes through a port of entry along the southwestern border, often more than once, due to the
increasing integration of manufacturing processes in the United States and Mexico. The bilateral
efforts discussed below have contributed to reductions in wait times at some points of entry, but
infrastructure and staffing issues remain on both the U.S. and Mexican sides of the border.145
On May 19, 2010, the United States and Mexico declared their intent to collaborate on enhancing
the U.S.-Mexican border as part of pillar three of the Mérida Initiative.146 A Twenty-First Century
Border Bilateral Executive Steering Committee (ESC) has met annually since then, most recently
in November 2017, to develop binational action plans and oversee implementation of those plans.
The plans set goals within broad objectives: coordinating infrastructure development, expanding
trusted traveler and shipment programs, establishing pilot projects for cargo preclearance,
improving cross-border commerce and ties, and bolstering information sharing among law
enforcement agencies. In 2015, the two governments opened the first railway bridge in 100 years
at Brownsville-Matamoros and launched three cargo pre-inspection test locations where U.S. and
Mexican customs officials are working together.147 A Mexican law allowing U.S. customs
personnel to carry arms in Mexico hastened these bilateral efforts.
As Congress carries out its oversight function on U.S.-Mexican migration and border issues,
questions that may arise include the following: 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 Central American migration through its territory? What is the
current level of bilateral cooperation on border security and immigration and border matters, and
how might that cooperation be improved? How well are the U.S. and Mexican governments
balancing security and trade concerns along the U.S.-Mexican border? To what extent would the
construction of a new border wall affect trade and migration flows in the region?

Mexico: Background and U.S. Relations

Energy148
The future of energy production in Mexico is important for Mexico’s economic growth and for
the U.S. energy sector. Mexico has considerable oil and gas resources, but its state oil company,
Petroleos Mexicanos (Pemex), has struggled to counter declining production and has postponed
needed investments due to fiscal challenges. Mexico’s 2013 constitutional reforms on energy
opened up oil, electricity, gas, transmission, production, and sales to private and foreign
investment while keeping ownership of Mexico’s hydrocarbons under state control, as established
in its 1917 constitution.
The 2013 reforms created opportunities for U.S. businesses in exploration, pipeline construction
and ownership, natural gas production, and commercial gasoline sales. Although the reforms did
not privatize Pemex, they did expose the company to competition and hastened its entrance into
joint ventures. Because of the reforms, Mexico has received more than $220 billion in promised
investment. 149 However, the reforms ended subsidies that kept gasoline prices low for Mexican
consumers and failed to reverse production declines and ongoing problems within Pemex.
The United States has sought to help lock in Mexico’s energy reforms through the ongoing
NAFTA renegotiations. NAFTA includes some reservations for investment in Mexico’s energy
sector. The proposed U.S.-Mexico free trade agreement announced on August 27, 2018,
reportedly would reinforce Mexico’s 2013 constitutional reforms and the current legal framework
for private energy projects in Mexico.150 It also would apply similar investor-state dispute
settlement mechanisms that currently exist in NAFTA to the oil and gas, infrastructure, and other
energy sectors. Additionally, the free trade agreement would allow for expedited exports of U.S.
natural gas to Mexico, which have increased about 130% since the 2013 reforms.
Private sector trade, innovation, and investment have created a North American energy market
that is interdependent and multidirectional, with more than 25 cross-border gas pipelines on the
U.S.-Mexican border alone.151 Some experts estimate that the United States, Mexico, and Canada
represent 20% of global oil and gas supply, as well as 20%-25% of the expected additions to
international supply over the next 25 years. They believe that deepened energy cooperation with
Mexico will give North America an industrial advantage.152
There is some uncertainty regarding López Obrador’s plans for Mexico’s energy sector. Although
López Obrador once opposed the 2013 reforms, he and his future Cabinet officials have said that
his government will honor existing contracts that do not involve any corruption.153 It is unclear,
however, whether the incoming government will seek to scale back the reforms or the pace of
their implementation. In July 2018, López Obrador announced an energy plan that included $2.6
billion to upgrade six existing refineries and $8.6 billion to construct a new refinery in Tabasco.154

His plan also includes a significant focus on revitalizing Pemex, although the person he has
appointed to head the company lacks experience in the sector. The plan also includes a focus on
renewable energy; Mexico already has attracted significant investment in its wind and solar
sectors.
Opportunities exist for continued U.S.-Mexican energy cooperation in the hydrocarbons sector,
but the future of those efforts may depend on the policies adopted by the López Obrador
government. Leases have been awarded in the Gulf of Mexico under the U.S.-Mexico
Transboundary Agreement, which was approved by Congress in December 2013 (P.L. 113-67).
Bilateral efforts to ensure that hydrocarbon resources are developed without unduly damaging the
environment could continue, possibly through collaboration between Mexican and U.S.
regulatory entities. Educational exchanges and training opportunities for Mexicans working in the
petroleum sector could expand. The United States and Mexico could build upon efforts to provide
natural gas resources to help reduce energy costs in Central America and connect Mexico to the
Central American electricity grid, as discussed at a June 2017 conference on Central America
cohosted by both governments.155 Analysts also have urged the United States to provide more
technical assistance to Mexico—particularly in deepwater and shale exploration.
In addition to monitoring energy-related issues as they pertain to NAFTA, oversight questions
may focus on how the Transboundary Hydrocarbons Agreement is implemented, the extent to
which Mexico is developing capable energy-sector regulators, and the effects of transnational
crime groups and violence on Mexico’s energy industry and the safety of foreign workers
employed in the energy sector. An emerging issue for congressional oversight may involve the
fairness of policies adopted by the incoming Mexican government toward foreign investors.
Water and Floodplain Issues156
The United States and Mexico share not only a border but also multiple rivers. These shared
rivers have long presented complex issues leading to cooperation and conflict in the U.S.-
Mexican border region and between the United States and Mexico.
The future of U.S.-Mexican border water relations depends on hydrologic conditions (e.g.,
drought, hurricanes), as well as the political environment and leadership. An acting official is
functioning as the U.S. commissioner of the International Boundary and Water Commission
(IBWC), the official responsible for compliance on a range of boundary and water treaties.
President Trump may affect the context through his appointment of a U.S. IBWC commissioner
and his interactions with Mexican officials. President-elect López Obrador is scheduled to assume
office on December 1, 2018; his positions on border water issues remain undefined.
IBWC and Water-Related Border Treaties. A binational water treaty in 1944 (referred to herein
as the 1944 Water Treaty) established a framework to address border water-related disputes and
developments, allocated water between the United States and Mexico in the Colorado River and
the Rio Grande below Fort Quitman, TX, and established the IBWC. The commission develops,
with approval by the executive branches of both nations, interpretations of the 1944 Water Treaty,
called minutes. Treaty minutes often are used to enhance bilateral cooperation and guide treaty

Mexico: Background and U.S. Relations

compliance. The IBWC is a binational entity with a U.S. Section that operates under foreign
policy guidance from the U.S. Department of State.
Under the 1944 Water Treaty, the United States is required to provide Mexico annually with 1.5
million acre-feet (AF) of Colorado River water. U.S. deliveries to Mexico in the Rio Grande basin
near El Paso/Ciudad Juárez occur annually under a 1906 binational convention, whereas
Mexico’s deliveries downstream of Fort Quitman, TX, are established in the 1944 Water Treaty.
Mexico is to deliver to the United States a minimum amount during a five-year cycle. IBWC also
administers other binational boundary and water-related agreements and projects for flood control
and sanitation (principally wastewater treatment facilities) and binational reservoirs.
Recent Developments in the Colorado River Basin. Minute 323, signed on September 21,
2017, is a set of binational cooperative measures in the Colorado River basin. It provides for more
cooperative basin water management, including environmental flows to restore riverine habitat.
Minute 323 also provides for Mexico to share in cutbacks during shortage conditions in the basin;
such cutbacks are not required under the 1944 Water Treaty. Minute 323 designates a “Mexican
Water Reserve,” through which Mexico can delay its water deliveries from the United States and
store its delayed deliveries upstream at Lake Mead, thereby increasing the lake’s elevation. Lake
Mead elevation is the baseline used for determining shortage conditions and associated water
delivery cutbacks for the lower Colorado River basin states of Arizona, California, and Nevada.
For the Colorado River basin, issues before Congress may be largely related to oversight of
Minute 323 implementation and water management associated with potential shortage conditions.
Recent Development in the Rio Grande Basin. Mexico was 15% below its deliveries for the
2010 to 2015 period; Mexico made up that deficit by early 2016. The October 2015 to October
2020 cycle is under way; deliveries below the annual target for the first year were offset by
additional deliveries made in the second year. In recent years, IBWC reportedly has been working
toward a binational model for water management in the Rio Grande and obtaining input from
binational working groups with the objective of improved predictability and reliability in water
deliveries and treaty compliance. To date, Congress has been primarily involved in conducting
oversight through reporting requirements for the U.S. Department of State. For FY2018, H.Rept.
115-253 included the following direction from the House Appropriations Subcommittee on State,
Foreign Operations, and Related Programs:
The Committee notes the treaty obligations of Mexico to supply water deliveries to the Rio
Grande and recognizes the importance of transparency concerning such matters. The
Committee directs International Boundary and Water Commission (IBWC) to regularly
publish water delivery data on its Web site, including projections for the balance of water
deliveries. The Committee expects IBWC to hold quarterly meetings with interested
stakeholders to inform them of IBWC activities and receive feedback.
Pursuant to the various reporting requirements, various reports have been delivered to various
committees of Congress, including as recently as March 2018. The 2014 farm bill (P.L. 113-79)
reporting requirement remains in effect; it requires an annual report from the Secretary of State on
efforts by Mexico to meet its treaty deliveries of water to the Rio Grande. The 115th Congress is
considering various bills that have accompanying reports with references to reporting on Rio
Grande water topics. For example, the Senate report for FY2019 Department of State
appropriations—S.Rept. 115-282 accompanying S. 3108—would continue the reporting
requirement.157 The House report—H.Rept. 115-829 accompanying H.R. 6385—for FY2019

157 The language states: “Not later than 45 days after enactment of the act, the Secretary of State,

appropriations—would continue report language requiring the publishing of data and holding of
stakeholder meetings, similar to H.Rept. 115-253.
Recent Development in Wastewater and River Pollution. On border wastewater issues,
congressional appropriators have shown interest in increasing oversight through statements and
reporting requirements related to the pollution in the Tijuana River. Authorizing committees have
engaged on issues related to wastewater management near Nogales, AZ.
Border Floodplain Encroachment. Discussion of increased U.S. security measures along the
border, particularly the border between Texas and Mexico, may revive concerns regarding
compliance with treaty provisions related to the construction of structures in the binational
floodplain that increase flood risk.158 In 2012, Minute 319 established a set of binational
cooperative measures in the Colorado River basin.
Environment and Renewable Energy Policy
In addition to the water management and conservation issues addressed by the IBWC, the U.S.
and Mexican governments have worked together on broader environmental issues in the border
region since signing the La Paz Agreement in 1983.159 Led by the U.S. Environmental Protection
Agency (EPA) and the Mexican secretary of environmental resources, the agreement committed
the two governments to regularly consult and review environmental concerns. Federal funding
and interest in border environmental issues peaked in the 1990s during the negotiations for and
implementation of the environmental side agreement to NAFTA that created the North American
Development Bank (NADB) and the Border Environment Cooperation Commission (BECC).160

Mexico to the United States to meet annual water apportionments to the Rio Grande, in
accordance with the 1944 Treaty between the United States and Mexico Respecting Utilization of
Waters of the Colorado and Tijuana Rivers and of the Rio Grande, and actions taken to minimize
or eliminate future water deficits to the United States.”
158 Article IV of the 1970 Treaty to Resolve Pending Boundary Differences and Maintain the Rio Grande and Colorado

Both in the main channel of the river and on adjacent lands to a distance on either side of the

each Contracting State shall prohibit the construction of works in its territory which, in the
judgement of the Commission, may cause deflection or obstruction of the normal flow of the river
or its flood flows.
It further describes that any works causing adverse flood effects shall be removed or modified and that repair or
compensation for damages provided. In the late 2000s and early 2010s during construction of border fencing,
particularly in the lower Rio Grande Valley of Texas, various stakeholders, including representatives from the Mexico
section of the IBWC according to news reports, raised concerns related to construction of security works within the
shared U.S.-Mexico floodplain (S. Nicol, “New Border Walls Designed to Flood Texas Towns,” Texas Observer, July
11, 2012; C. Sherman, “U.S., Mexico disagree over border fence plan in Texas,” Houston Chronicle, July 24, 2012.).

Mexico: Background and U.S. Relations

Even after federal funding for border environmental projects decreased post-2000, the U.S. and
Mexican governments have continued to design and implement binational environmental
programs.161 The current 10-year border program, Border 2020, is focused on cooperation in five
areas: (1) reducing air pollution; (2) improving access to clean water; (3) promoting materials and
waste management; (4) enhancing joint preparedness for environmental response; and (5)
enhancing environmental stewardship. The Trump Administration’s FY2019 budget request
would zero out funding and staff for the U.S.-Mexican border programs run by the EPA.162 In
FY2018, the Administration did not requested any funding for the programs, but Congress
provided $3.0 million in EPA funding.
In 2009, President Obama and then-President Calderón announced the Bilateral Framework on
Clean Energy and Climate Change to jointly develop clean energy sources and encourage
investment in climate-friendly technologies. Among others, its goals included enhancing
renewable energy, combating climate change, and strengthening the reliability of cross-border
electricity grids. USAID and Mexico also expanded cooperation through the Mexico Global
Climate Change (GCC) Program, which began in 2010 and provided $50 million in funding
through FY2016, although bilateral efforts on climate change began around 1990.163 By 2016,
environmental protection and clean energy became a priority for North American cooperation.164
Mexico, Canada, and the United States all became parties to the Paris Agreement, which entered
into force on November 4, 2016,165 under the U.N. Framework Convention on Climate Change.
The Mexican congress and the Canadian parliament ratified the Paris Agreement.166 In contrast,
U.S. executive branch officials stated that the Paris Agreement is an executive agreement not
requiring Senate advice and consent to ratification.167 President Obama signed an instrument of
acceptance on behalf of the United States on August 29, 2016, without submitting it to Congress.
On June 1, 2017, President Trump announced his intention to withdraw from the Paris
Agreement.168 The Administration’s FY2018 budget request, released on May 23, 2017, proposed
to “eliminate U.S. funding for the Green Climate Fund (GCF) in FY2018, in alignment with the
President’s promise to cease payments to the United Nations’ climate change programs.” The
dFY2018 budget request also eliminates funding for Global Climate Change programs run by
USAID, the Department of State, and the Department of the Treasury. Congress did not provide
funding for those programs in FY2018. Given these developments, it is unlikely that trilateral
efforts on advancing clean energy and meeting the aforementioned emissions targets will
continue under the Trump Administration.

Mexico: Background and U.S. Relations

Educational Exchanges and Research
Educational and research exchanges between the United States and Mexico have been occurring
for decades, but they rose higher in the bilateral agenda during the Obama Administration as part
of the High-Level Economic Dialogue. In 2011, President Obama established a program called
“100,000 Strong in the Americas” to boost the number of U.S. students studying in Latin America
(including Mexico) to 100,000 (and vice versa) by 2020. Similarly, President Peña Nieto has
implemented Proyecta 100,000, which aims to have 100,000 Mexican students and researchers
studying in the United States by 2018. Together, the U.S. and Mexican governments launched a
Bilateral Forum on Higher Education, Innovation, and Research (FOBESII) in May 2013, which
has led to more than 80 partnerships between U.S. and Mexican universities.169 Both programs
are still being implemented.
Country and bilateral efforts face continued challenges. In 2015-2016, the number of U.S.
students studying in Mexico increased by 6% compared to 2014-2015, but the number of
Mexicans studying in the United States decreased by 1.9%.170 Mexico ranks 10th on the Institute
of International Education’s list of countries with students studying in the United States. China is
number one, and Brazil is number eight. A lack of scholarship funding and a lack of English
language skills have been barriers for many Mexican students.
Outlook
President Peña Nieto began his Administration focused on enacting economic reforms. By 2014,
it appeared that Peña Nieto’s economic agenda could not be successful without addressing the
country’s rule-of-law challenges. Four years later, President Peña Nieto’s approval ratings are at
historic lows for a Mexican president, largely due to his government’s inability to tackle those
issues. Numerous former PRI governors are facing criminal charges, and President Peña Nieto is
fending off allegations of corruption within the PRI and his 2012 campaign, as well as charges
that his government used spyware to illegally spy on its critics. His government has been
criticized for not defending Mexican interests more vigorously vis-à-vis the positions of President
Trump, but Peña Nieto has been careful not to use rhetoric or take tough positions that could
alienate the U.S. administration and risk a U.S. withdrawal from NAFTA.
As Mexico’s July 1, 2018, elections approach, observers predict that the election is likely to be
extremely close, particularly given the participation of independent candidates. Some analysts are
concerned that Mexicans may elect López Obrador, a leftist who may be less inclined to continue
close bilateral cooperation with the United States in some areas than others candidates.171 López
Obrador’s supporters maintain that he is a progressive who wants to take on corruption within
Mexico and maintain good relations with the United States, while his opponents denounce him as
a populist who would implement socialist policies and antagonize the United States.172 Whoever
wins the Mexican presidency is likely to inherit a difficult security and economic situation that
will be influenced, at least in part, by developments in the United States and U.S. trade, drug, and
immigration policy.

sectors except telecommunications and energy and gives the commission the power to oversee mergers,
regulate industries, and sanction monopolistic practices.

Telecommunications Reform: Increases consumers’ access to more affordable and reliable television,
radio, Internet, and mobile phone services; increases privacy protections for consumers; 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 (SMEs),
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) to 16% from 11% in northern border states and creating new taxes on stock market
profits, as well as sugary beverages and other snack foods.

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. In
June 2015, Mexico’s Supreme Court upheld the constitutionality of removing teachers who fail evaluation
exams from instructional positions.

Unified Code of Criminal Procedure (CPC): Replaces the procedural rules that existed in the country
so that the same general rules apply to all states and the federal government; facilitates coordination between
authorities; and aims to improve the efficiency of investigations. As a result of the unified code, all states will
have oral, adversarial trials with the presumption of innocence and the use of alternative dispute mechanisms
as required by constitutional reforms enacted in 2008.

Political Reform: Provides for the reelection of federal deputies for up to four terms beginning in 2015 and
of senators for up to two terms beginning in 2018; provides for 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.

Transparency Reform: Extends the rights of citizens to seek information from all levels of government,
unions, and political parties and strengthens the entity charged with managing access to information (the
Federal Institute of Access to Information and Data Protection).
