Inside Costa Rica’s foreign policy.

Costa Rica’s foreign policy is built on legalism, demilitarization, and trade openness, but the hierarchy underneath is harder-edged: territorial security and regime stability now sit above its older branding as a purely normative middle power. Costa Rica has had no standing army since Article 12 of its Constitution abolished it in 1949, and it still presents international law, human rights, and multilateral dispute settlement as core principles of external action Constitución Política de Costa Rica, Ministry of Foreign Affairs and Worship of Costa Rica. But President Laura Fernández Delgado took office in June 2026 on a security-focused agenda after an election shaped heavily by organized crime and border concerns, which shifts the operational center of gravity toward public security, border control, and management of spillover from Nicaragua and regional trafficking routes The Tico Times, Latinoamérica 21. In practical terms, the presidency and executive ministries, especially foreign affairs and public security, hold the file; the legislature matters, but the president sets the diplomatic line unless treaty ratification is at issue Constitución Política de Costa Rica.

Costa Rica’s core interests are unusually clear. Survival-level interests center on sovereignty at the northern border, especially in relation to Nicaragua, with which Costa Rica has had repeated territorial and river-navigation disputes adjudicated through international law, including at the International Court of Justice International Court of Justice, International Court of Justice. Regime-security interests now include containing transnational criminal violence that threatens public order, tourism, and investor confidence; homicide and narcotics trafficking have become major domestic drivers of foreign policy coordination with the United States and regional partners UN Office on Drugs and Crime. Economic interests come next: Costa Rica joined the OECD in 2021, tying its diplomacy more closely to rules-based investment, tax cooperation, and regulatory credibility OECD, while trade and investment promotion remain central through CAFTA-DR and deep integration into medical devices, electronics, and services exports Office of the United States Trade Representative, World Bank Data. Status matters too, but mainly as an instrument: Costa Rica uses climate diplomacy, human rights advocacy, and its army-free identity to win influence disproportionate to its size UN Climate Change, UN Human Rights Council.

Its bilateral map reflects that mix of principle and exposure. The United States is the decisive external partner on security cooperation, trade, migration management, and investment, even when San José avoids language that implies alignment politics U.S. Department of State, USTR. Relations with Nicaragua are the sharpest bilateral problem: Costa Rica has repeatedly objected to Nicaraguan security and sovereignty behavior and, according to reporting on the new administration’s first days, raised concern over Russian military presence in Nicaragua, a sign that San José increasingly reads Managua through both border-security and extra-regional competition lenses The Tico Times. Costa Rica also keeps functional relations across Central America through SICA, but regional solidarity is limited by democratic backsliding in some neighboring states and by uneven migration burdens Sistema de la Integración Centroamericana, Organization of American States. Ties with Europe are stronger than Costa Rica’s size would suggest because of shared positions on climate, human rights, and trade governance, reinforced by the EU-Central America Association framework European Commission.

In multilateral institutions, Costa Rica behaves like a small-state proceduralist that often votes with liberal democracies on human rights, humanitarian law, and institutional accountability, but it is not a simple bloc follower. It is a UN founding member and active in the OAS, SICA, OECD, and broader climate forums United Nations Member States, OECD, SICA. At the UN General Assembly, Costa Rica has generally supported resolutions critical of Russia’s aggression against Ukraine and has backed rights-focused positions on Nicaragua, consistent with its stated commitment to sovereignty and democratic norms United Nations Digital Library, UN General Assembly ES-11 resolutions. Its most revealing divergence from parts of Latin America is that it is less attached than some neighbors to reflexive non-intervention when democratic erosion or cross-border security threats are involved. San José still invokes international law, but it is more willing than governments in CELAC’s sovereigntist wing to internationalize disputes, support scrutiny of authoritarian behavior, and frame regional instability as a legitimate multilateral concern rather than a purely domestic matter OAS, ICJ.

That break matters because Costa Rica is often misread as a soft-power idealist when its actual pattern is selective activism under legal cover. It stays inside the Latin American tradition of negotiated diplomacy, but it departs from the bloc when legalism can be used against stronger or more coercive neighbors, especially Nicaragua. The
