Costa Rica is an active member of the international community and, in 1993, claimed it was for neutrality. Due to certain powerful constituencies favoring its methods, it has a weight in world affairs far beyond its size. The country lobbied aggressively for the establishment of the Office of the United Nations High Commissioner for Human Rights and became the first nation to recognize the jurisdiction of the Inter-American Human Rights Court, based in San Jose.

Then-President Oscar Arias authored a regional plan in 1987 that served as the basis for the Esquipulas Peace Agreement and Arias was awarded the 1987 Nobel Peace Prize for his work. Arias also promoted change in the USSR-backed Nicaraguan government of the era. Costa Rica also hosted several rounds of negotiations between the Salvadoran Government and the Farabundo Martí National Liberation Front (FMLN), aiding El Salvador's efforts to emerge from civil war and culminating in that country's 1994 free and fair elections. Costa Rica has been a strong proponent of regional arms-limitation agreements. Former President Miguel Ángel Rodríguez recently proposed the abolition of all Central American militaries and the creation of a regional counternarcotics police force in their stead.

With the establishment of democratically-elected governments in all Central American nations by the 1990s, Costa Rica turned its focus from regional conflicts to the pursuit of neoliberal policies on the isthmus. The influence of these policies, along with the US invasion of Panama, was instrumental in drawing Panama into the Central American model of neoliberalism. Costa Rica also participated in the multinational Partnership for Democracy and Development in Central America.

Regional political integration has not proven attractive to Costa Rica. The country debated its role in the Central American integration process under former President Calderon. Costa Rica has sought concrete economic ties with its Central American neighbors rather than the establishment of regional political institutions, and it chose not to join the Central American Parliament. President Figueres promoted a higher profile for Costa Rica in regional and international fora. Costa Rica gained election as President of the Group of 77 in the United Nations in 1995. That term ended in 1997 with the South-South Conference held in San Jose. Costa Rica occupied a nonpermanent seat in the Security Council from 1997 to 1999 and exercised a leadership role in confronting crises in the Middle East and Africa, as well as in the former Socialist Federal Republic of Yugoslavia. It is currently a member of the United Nations Commission on Human Rights.

Costa Rica broke relations with Cuba in 1961 to protest Cuban support of the left in Central America and has not renewed formal diplomatic ties with the Castro regime. In 1995, Costa Rica established a consular office in Havana. Cuba opened a consular office in Costa Rica in 2001.

Costa Rica strongly backed efforts by the United States to implement UN Security Council Resolution 940, which led to the restoration of the democratically elected Government of Haiti in October 1994. Costa Rica was among the first to call for a postponement of the May 22 elections in Peru when international observer missions found electoral machinery not prepared for the vote count.

Costa Rica maintains official relations with the Republic of China (commonly known as "Taiwan") instead of the People's Republic of China. Strong economic ties exist between the two countries with projects having included the recent construction of a suspension bridge with Taiwanese capital to join the Costa Rican mainland with the Nicoya Peninsula. The bridge is expected to be a boon for the tourist industry in the peninsula by reducing travel time to some locations by as much as two hours.
