Inside Guyana’s foreign policy.

Guyana’s foreign policy is defensive, legalistic, and increasingly energy-backed. President Irfaan Ali remains the central external actor under Guyana’s presidential system, with Prime Minister Mark Phillips serving as head of government and Hugh Todd as foreign minister; Ali’s office has led the country’s response to the Venezuela border crisis while the Foreign Ministry carries the diplomatic file in CARICOM, the OAS, the UN, and the ICJ process Office of the President of Guyana, Ministry of Foreign Affairs and International Cooperation of Guyana. The hierarchy of interests is clear: survival comes first in defending sovereignty over the Essequibo, regime and state security follow through military and diplomatic partnerships, economic interest centers on protecting offshore oil production and export routes, and status comes last through Guyana’s attempt to act as a serious small-state voice in CARICOM, climate talks, and the UN International Court of Justice, U.S. Department of State, IMF.

Guyana does not operate from a single published grand-strategy doctrine in the way larger powers do; its practical doctrine is built from repeated official positions: strict respect for sovereignty, peaceful settlement of disputes, non-interference, multilateralism, and international law, especially the 1899 Arbitral Award and the ICJ case rejecting Venezuela’s territorial claim to Essequibo Ministry of Foreign Affairs and International Cooperation of Guyana, International Court of Justice, CARICOM. That stated legalism is matched by behavior. Georgetown has pursued adjudication at the ICJ, sought OAS, CARICOM, Commonwealth, and UN backing, and deepened security cooperation with the United States and other partners after Venezuela’s December 2023 referendum and subsequent pressure campaign International Court of Justice, Organization of American States, U.S. Southern Command, CARICOM. The non-obvious point is that Guyana’s oil boom has not made it revisionist; it has made it more invested in the existing legal order because that order is what shields both its territory and its offshore energy assets.

Its key bilateral relationships reflect that ranking of interests. The United States is now Guyana’s most important extra-regional security and energy partner, with cooperation spanning military exercises, maritime domain awareness, and support for territorial integrity as U.S. firms, especially ExxonMobil-led operations, dominate offshore production U.S. Department of State, U.S. Southern Command, ExxonMobil Guyana. Brazil matters for a different reason: it is the crucial continental neighbor linking Guyana to South America by road, trade, and quiet security coordination, while also preferring de-escalation with Venezuela Government of Brazil, Reuters. CARICOM partners, especially Barbados and Trinidad and Tobago, give Guyana diplomatic depth and regional legitimacy, and the Commonwealth adds another venue for backing on sovereignty questions CARICOM, The Commonwealth. Venezuela is the clear rival: the territorial dispute dominates Guyanese threat perception, and nearly every major foreign-policy choice is filtered through deterrence, coalition-building, and legal containment of Caracas’s claim International Court of Justice, BBC.

Regionally and multilaterally, Guyana behaves like a small state that needs institutions to multiply weight. It is active in CARICOM, the OAS, the Commonwealth, the UN, and the Non-Aligned Movement, and it has also used its elected seat on the UN Security Council for 2024–2025 to raise its diplomatic profile beyond what its size would normally permit United Nations Security Council, CARICOM, OAS. At the UN, Guyana’s voting pattern generally tracks the broad Global South and CARICOM line on development, decolonization, climate vulnerability, and support for Palestinian rights, while still defending the UN Charter’s sovereignty principles in ways that align closely with Western positions on its own border issue United Nations Digital Library, Permanent Mission of Guyana to the United Nations. It is also using climate diplomacy pragmatically: as a state with major new hydrocarbon output, it continues to market the Low Carbon Development Strategy as proof that oil income can fund forest protection rather than displace it Government of Guyana, LCDS 2030, UNFCCC.

The most analytically useful divergence is that Guyana is formally Non-Aligned and part of a Caribbean bloc that often prefers rhetorical distance from great-power competition, but in practice it has moved closer to the United States on security faster than many CARICOM peers because Venezuela creates an immediate territorial threat Non-Aligned Movement, U.S. Department of State, CARICOM [blocked]
