Foreign relations of Guyana

After independence in 1966, Guyana sought an influential role in international affairs, particularly among Third World and non-aligned nations. It served twice on the UN Security Council (1975–76 and 1982–83). Former Vice President, Deputy Prime Minister, and Attorney General Mohamed Shahabuddeen served a 9-year term on the International Court of Justice (1987–96). In June 2023, Guyana was elected as a non-permanent member to the UN Security Council. The country will serve on the Council for a period of two years, beginning in January 2024.

Guyana has diplomatic relations with a wide range of nations, and these are managed primarily through its Ministry of Foreign Affairs. The European Union (EU), the Inter-American Development Bank (IDB), the UN Development Programme (UNDP), the World Health Organization (WHO), and the Organization of American States (OAS) have offices in Georgetown.

Regional relations
Guyana strongly supports the concept of regional integration. It played an important role in the founding of the Caribbean Community and Common Market (CARICOM), but its historic status as the organization's poorest member limited its ability to exert leadership in regional activities. Since discovering and developing its offshore oil and gas reserves, Guyana has been reclassified by the World Bank as a high-income country. Guyana has sought to keep foreign policy in close alignment with the consensus of CARICOM members, especially in voting in the UN, OAS, and other international organizations. In 2022, Guyana joined the Regional Security System. The 2023 Guyana–Venezuela crisis has compelled Guyana to expand defense and security relations with a variety of countries, namely Brazil, the United States, India, and the United Kingdom.

International disputes
All of the area west of the Essequibo River has at one point been under dispute, namely by Venezuela and Brazil. In 1899, the government in Caracas reluctantly accepted the Venezuelan-Guyanese border but later revived its claim to the Essequibo in 1962. Suriname has an ongoing dispute with Guyana and this pertains to the area east of the Upper Courantyne.

Currently, two neighbours have longstanding territorial disputes with Guyana. Since the 19th century, Venezuela has claimed the majority or all of Guyana situated west of the Essequibo River – 62% of Guyana's territory. At a meeting in Geneva in 1966, the two countries agreed to receive recommendations from a representative of the UN Secretary General on ways to settle the dispute peacefully. Diplomatic contacts between the two countries and the Secretary General's representative continue. In December 2023 president Nicolás Maduro called for a public referendum which resulted in the government of Venezuela officially claiming ownership of the Essequibo, claim that resulted in the 2023 Guyana–Venezuela crisis.

Neighbouring Suriname also claims the territory east of Guyana's New River, a largely uninhabited area of some 15000 km2 in southeast Guyana. Guyana and Suriname also disputed their offshore maritime boundaries. This dispute flared up in June 2000 in response to an effort by a Canadian company to drill for oil under a Guyanese concession. Guyana regards its legal title to all of its territory as sound. However, the dispute with Suriname was arbitrated by the United Nations Convention on Law of the Sea and a ruling in favor of Guyana was announced in September 2007.

Crime
In 1993, Guyana ratified the 1988 Vienna Convention on illicit traffic in narcotic drugs and cooperates with US law enforcement agencies on counter-narcotics efforts. Guyana is also a member of the International Criminal Court with a Bilateral Immunity Agreement of protection for the US-military (as covered under Article 98).

Guyana has been considered a transshipment point for narcotics from South America, primarily Venezuela, to Europe and the United States and producer of cannabis.
