From the Document: "Located on the northern coast of South America between Suriname and Venezuela, English-speaking Guyana has characteristics similar to other Caribbean nations because of their common British colonial heritage (Guyana became independent in 1966). The country participates in Caribbean regional organizations, and its capital, Georgetown, serves as headquarters for the Caribbean Community (CARICOM), a regional integration organization. Once one of the poorest countries in the hemisphere, Guyana's development prospects have shifted significantly since the discovery of large offshore oil deposits in 2015."
