The Organization of American States

The Organization of American States is an important forum for regional diplomacy and has become more assertive in promoting the rule of law, human rights, and fair elections as some states face domestic upheaval.

The Organization of American States (OAS) is a multilateral regional body focused on human rights, electoral oversight, social and economic development, and security in the Western Hemisphere. While the organization is recognized by many foreign policy experts as an important forum for regional diplomacy, critics say ideological divisions among its members have hampered its efforts to promote democratic principles.

The OAS has come under renewed focus in recent years for criticizing democratic decline in Nicaragua and persistently condemning Venezuelan President Nicolás Maduro. Since the 2021 killing of Haiti’s president, Jovenel Moïse, the country’s deteriorating security climate has also posed a challenge for the bloc, and Russia’s 2022 invasion of Ukraine has proved to be yet another divisive issue. While President Donald Trump showed his ambivalence toward the OAS by becoming the first U.S. president to skip its headline meeting, President Joe Biden has signaled his administration’s desire to renew U.S. leadership in the Western Hemisphere.

The United States and twenty other governments in the Western Hemisphere signed the OAS charter in 1948 to increase regional security and commercial cooperation. Additionally, the United States hoped the new organization would serve as a bulwark against the spread of communism. Member states pledged to strengthen regional peace and security, promote representative democracy, and encourage economic and social cooperation. The OAS emerged a year after member states signed the Inter-American Treaty of Reciprocal Assistance, known as the Rio Treaty, which established a defensive military alliance in the region. Since then, its membership has increased to thirty-five states; the number of permanent observers dropped to seventy-one in April 2022 after Russia was suspended in response to its invasion of Ukraine.



How is the OAS organized?

The OAS is headed by Secretary-General Luis Almagro, Uruguay’s former foreign minister, who assumed office in 2015. It comprises three main bodies [PDF]: the General Assembly, the principal decision-making organ, which meets annually; the Permanent Council, which manages day-to-day affairs; and the General Secretariat, which implements policies made by the other two bodies.

The OAS is headquartered in Washington, DC, and has more than seven hundred employees throughout the Americas. It convenes a Summit of the Americas every two to four years, during which national leaders discuss multilateral initiatives and work to reinforce diplomatic ties. The most recent summit took place in June 2022 in Los Angeles, California, where OAS members addressed the theme “building a sustainable, resilient, and equitable future” amid growing economic insecurity, climate instability, and political polarization. However, President Biden’s decision to exclude Cuba, Nicaragua, and Venezuela led the leaders of several countries—including Guatemala, Honduras, and Mexico—to boycott the gathering [PDF]. Major outcomes of the summit included the creation of a U.S.-Caribbean partnership to mitigate the impact of climate change on Caribbean nations and a pact aimed at addressing the region’s growing migration crisis.

What does the OAS do?

Its primary functions are promoting democracy, coordinating security and law enforcement operations, providing technical and financial assistance for development projects, and monitoring human rights through the inter-American legal system. Several autonomous institutions carry out OAS functions, including the Inter-American Commission on Human Rights (IACHR) and the Inter-American Juridical Committee.  

In 2021, the OAS sent election observation missions to Bolivia, El Salvador, and Peru, among other countries. Other recent initiatives include establishing a working group [PDF] to address mass migration from Venezuela; supporting the creation of an anticorruption commission in El Salvador; and collaborating with member governments, regional institutions, and private companies to improve cybersecurity. The OAS currently has observation missions in six countries: Brazil, Colombia, Costa Rica, Grenada, Mexico, and Saint Kitts and Nevis.

What is its budget?

The OAS has a regular fund that supports the General Secretariat, and a specific fund geared toward particular programs and initiatives. The General Assembly finances the regular fund by setting country quotas, which are based on members’ capacities to pay. The OAS’s 2022 budget [PDF] allocates $81 million to the regular fund, of which the United States is required to provide [PDF] a little more than $45 million, or about 56 percent. Between January and June 2022, the United States voluntarily gave [PDF] more than $12 million to the specific fund, accounting for roughly 49 percent of contributions [PDF] in that period.

What are its strengths?

The OAS’s role as a forum for regular high-level discussions on issues facing the hemisphere is one of its major strengths, says CFR’s Shannon K. O’Neil. Several other analysts have praised the IACHR as a crucial, objective platform for human rights litigation. For instance, the commission played an important role in uncovering rights abuses committed during several of the region’s military dictatorships in the 1970s and 1980s. The OAS “took forceful stands to defend democracy in Haiti, Peru, Guatemala, and Paraguay” in the 1990s, writes Michael Shifter, former president of the Inter-American Dialogue.

What are its weaknesses?

Many policymakers from member states have criticized the OAS for institutional shortcomings. Experts say the region’s polarized politics have made it difficult for the OAS to make quick, decisive calls to action and maintain its role as an impartial moderator.

Moreover, many members have become more reluctant to empower independent monitoring agencies. In 2016, the IACHR announced layoffs and suspended hearings due to budget cuts, which Shifter says were largely due to members’ failing to meet their financial responsibilities. “For a number of governments, bolstering a genuinely autonomous body that would enhance scrutiny of their human rights records is hardly a high priority,” he writes.

Election monitoring is also constrained: OAS observers can deploy only to countries that have invited them. For example, in 2016, the United States invited OAS observers for the first time to oversee the country’s polarized presidential election. In 2022, the OAS deployed to Brazil for a presidential election held amid concerns that a constitutional crisis could ensue should President Jair Bolsonaro lose his reelection bid. Several other organizations also monitored the election, including the South American trade bloc Mercosur and the U.S.-based International Foundation for Electoral Systems.

Nevertheless, it has become a norm in many member countries to accept OAS monitors, which O’Neil says has been helpful in ensuring the legitimacy of elections. After observers expressed concern about vote counting during Bolivia’s 2019 presidential election, an OAS audit [PDF] found “clear manipulations” favoring President Evo Morales. The body recommended a new election, but Morales resigned amid widespread protests and under military pressure. Some researchers have since questioned the OAS’s allegations, arguing that there was no statistical evidence of election fraud.

Still, some critics say that the bloc has occasionally offered legitimacy to flawed elections, including in Honduras in 2009 and Haiti in 2011, while some members of the U.S. Congress argue that the OAS has failed to stop democratic erosion in countries such as Nicaragua and Venezuela.

How committed is the OAS to democracy?

The OAS has played an important role in promoting democracy since most of the hemisphere returned to civilian rule toward the end of the Cold War. In 1992, the OAS amended its charter to allow the suspension of states whose democratic governments are overthrown by force, and in 2001, members signed the Inter-American Democratic Charter, which declared that American states have a “right to democracy” and an “obligation to promote and defend it.” In 2009, members suspended Honduras following a military coup; the country was readmitted two years later after officials there held elections.

Since then, political pressure from the bloc has heightened significantly amid a humanitarian crisis that has caused more than seven million Venezuelans to flee the country. In 2018, Peru barred Maduro from that year’s Summit of the Americas, though Venezuela dominated the meeting’s plenary discussion. Sixteen OAS member states rebuked Caracas in a joint statement, but others, particularly Cuba, indicated support [PDF] for Maduro’s government.

Maduro ignored vociferous calls from Almagro and the OAS Permanent Council to postpone Venezuela’s 2018 presidential election until the rule of law was reinstated and elections sanctioned by international observers. In response, the regional bloc tried to initiate suspension proceedings against Venezuela, but the measure lacked sufficient support. However, the group dealt a blow to Maduro in April 2019 by recognizing opposition leader Juan Guaidó’s envoy as Venezuela’s representative to the OAS. In May 2021, the OAS publicly supported Guaidó’s efforts to unite the opposition around a plan to reestablish democratic order, which would include freeing political prisoners, allowing in international humanitarian aid, and distributing COVID-19 vaccines. During the 2022 OAS General Assembly in Lima, Peru, more than half of members voted in favor of ousting Guaidó’s representation to the bloc, though the motion fell short of the twenty-four votes needed to pass. Guaidó’s envoy did not attend the meeting. 

Tensions with Nicaragua, whose deteriorating democracy and worsening human rights situation previously drew criticism from the OAS, came to a head after the bloc declared the country’s November 2021 election to be illegitimate. In response, President Daniel Ortega announced Nicaragua’s withdrawal from the OAS, set to take effect in 2023. But in April 2022, his administration closed the OAS’s offices in the capital, Managua, and declared Nicaragua’s immediate split from the bloc. Additionally, the OAS Permanent Council has condemned the Ortega administration for its sentencing of political prisoners and continued repression of journalists and human rights defenders.

What is the organization’s history with Cuba?

The only country in the Western Hemisphere that is not a member of the OAS is Cuba, which has long been a wedge between member states. At the urging of the United States, the OAS suspended Cuba in 1962 on the grounds that its self-proclaimed Marxist-Leninist government was “incompatible with the principles and objectives of the inter-American system.”

In 2009, the OAS voted unanimously to lift the suspension on the condition that Cuba submit to a “process of dialogue” on OAS principles. In 2015, U.S. President Barack Obama met with Cuban President Raúl Castro on the sidelines of the Summit of the Americas—it was the first time a Cuban leader attended the summit—as part of a rapprochement many observers said could warm ties between Washington and much of Latin America.

However, Trump’s partial reversal of the détente introduced by Obama and Castro’s stated lack of interest in rejoining the OAS threw doubt on any such reconciliation. The OAS has remained critical of Cuba, denouncing the installation of Castro’s successor, Miguel Díaz-Canel, and condemning the government’s human rights record. In October 2019, Díaz-Canel rebuked the “troop of mediocre and duplicitous politicians pulled together in the OAS.” Months later, the IACHR released a report [PDF] detailing the poor human rights situation in Cuba, and in July 2021, the bloc condemned the Díaz-Canel administration’s use of force during nationwide protests.

What was the Trump administration's relationship with the OAS?

In an April 2017 statement, Trump called the OAS an “enduring organization for the promotion of democracy, security, human rights, and economic development.” His administration led OAS efforts to suspend Maduro’s Venezuelan delegation and recognize Guaidó’s envoy. However, the U.S. ambassador to the OAS received criticism in June 2019 from groups, including Haiti’s opposition, for attempting to intervene in the country’s volatile political situation. Some observers also allege that U.S. policymakers pressured the OAS to interfere in the Bolivian election and topple Morales, who called the United States a “great conspirator” in his fall from power.

In other ways, Trump de-emphasized the bloc, including by trying to cut funding. In 2018, his administration requested $8.75 million less than [PDF] the United States’ required contribution to the OAS budget for that year, though it ultimately did meet its $50.75 million quota [PDF]. Trump also skipped the 2018 summit, making it the first to be held without a sitting U.S. president. And in March 2019, Secretary of State Mike Pompeo announced that the Trump administration would cut funding to the OAS due to the organization’s support for legalizing abortion.

Many Latin American leaders expressed concerns over Trump’s stances on immigration, trade, and Cuba. Trump’s policies toward Latin America risked alienating an increasingly pro-trade, U.S.-friendly region, wrote Javier Corrales, a professor of political science at Amherst College.

How has Biden engaged with the bloc?

Biden entered office on promises to increase the U.S. focus on Latin America and reverse several policies enacted during the Trump administration, including by giving more aid to Venezuela’s opposition. He has expressed support for several of the OAS’s efforts to restore political stability in Cuba, Haiti, and Nicaragua, and extended temporary protected status to migrants from Haiti and Venezuela, among other countries. In July 2021, he nominated Francisco Mora, a professor at Florida International University, to be the next U.S. ambassador to the OAS, though Mora has not yet been confirmed by the U.S. Senate.

At the 2022 General Assembly, U.S. Secretary of State Antony Blinken announced that the United States will provide an additional $240 million in new aid, including education and legal assistance, for migrants and refugees across the Western Hemisphere. Meanwhile, the United States was among the majority of member countries that supported a declaration condemning Russia’s military deployment in Ukraine. Several countries, including Argentina, Brazil, and Mexico, refused to sign.

However, some critics say that the Biden administration has failed to prioritize regional goals, such as advancing U.S.-Cuba ties and political negotiations in Venezuela. Others, including several Republican members of Congress, have criticized the president for enacting policies they argue are incentivizing “waves of illegal immigration” [PDF] into the United States, particularly from the so-called Northern Triangle countries of El Salvador, Guatemala, and Honduras.

Are there regional alternatives to the OAS?

A handful of other regional groupings have emerged over the last two decades with different goals. Some seek to counter Washington’s perceived influence over the OAS, while others aim to streamline decision-making.

CELAC: The Community of Latin American and Caribbean States is an organization that excludes the United States and Canada and was widely seen as a potential alternative to the OAS when it was founded in 2010. Its achievements have included securing a 2015 pledge from Chinese President Xi Jinping to invest $500 billion in the region. In December 2021, the China-CELAC Forum released a two-year Joint Action Plan that aims to deepen multilateral cooperation between Beijing and the bloc, as well as create eight new forums that focus on topics including space and digital technology. At a second China-CELAC meeting the following July, the two groups agreed to deepen cooperation on poverty reduction and infrastructure development in the region. However, CELAC’s membership has shrunk in recent years; Brazil withdrew in 2020, arguing that the group is controlled by authoritarian regimes in Cuba, Nicaragua, and Venezuela. Argentina is currently occupying the bloc’s rotating presidency and has proposed focusing group efforts on several initiatives, including post-pandemic economic recovery, food security, and regional health cooperation.

UNASUR: The Union of South American Nations was founded in 2008 and regarded by many observers as a means for Brazil to assert its power in the region. The organization mediated a diplomatic crisis between Ecuador and Colombia in 2008, and participated in Vatican-led talks between Venezuela’s government and opposition leaders in 2016. However, it fell apart after more than half its member states suspended their involvement in 2018; only Bolivia, Guyana, Suriname, and Venezuela remain, while Mexico and Panama are observer states. 

Prosur: The Forum for the Progress of South America was formed in March 2019 by UNASUR’s defecting countries—Argentina, Brazil, Chile, Colombia, Ecuador, Paraguay, and Peru—plus Guyana. Venezuela was the only South American state not invited to join. Conveners envision it as a UNASUR substitute focused on socioeconomic cooperation, though analysts have questioned the bloc’s usefulness and staying power. Paraguayan President Mario Abdo Benítez has held the bloc’s annual rotating presidency since January 2022.

ALBA: The Bolivarian Alliance for the Peoples of Our America was founded in 2004 by Venezuelan President Hugo Chávez and Cuban President Fidel Castro. It comprises ten governments from the region (Ecuador withdrew in 2018) and seeks economic and political integration based on leftist ideals. Experts say its influence has diminished amid Venezuela’s economic and political disintegration.
