The newly independent Guyana at first sought to improve relations with its neighbors. For instance, in December 1965 the country had become a charter member of the Caribbean Free Trade Association (Carifta). Relations with Venezuela were not so placid, however. In 1962 Venezuela had announced that it was rejecting the 1899 boundary and would renew its claim to all of Guyana west of the Essequibo River. In 1966, Venezuela seized the Guyanese half of Ankoko Island, in the Cuyuni River, and two years later claimed a strip of sea along Guyana's western coast.
