Specific small disputed areas involving Guyana are Ankoko Island with Venezuela; Corentyne River with Suriname; and Tigri Area or New River Triangle with Suriname. In 1967 a Surinamese survey team was found in the New River Triangle and was forcibly removed. In August 1969 a patrol of the Guyana Defence Force found a survey camp and a partially completed airstrip inside the triangle, and documented evidence of the Surinamese intention to occupy the entire disputed area. After an exchange of gunfire, the Surinamese were driven from the triangle.
