evidence: Venezuela claimed more than half of the territory of the British colony of Guyana at the time of the Latin American wars of independence. Guyana argues that the boundary between the nations was clarified in the Arbitral Award of 1899 signed by Guyana, whereas Venezuela called the award an "Anglo-Russian conspiracy".[2] In 1962 Venezuela declared that it would no longer abide by the arbitration decision, which ceded mineral-rich territory in the Orinoco basin to Guyana. The disputed area is called "Guayana Esequiba" by Venezuela. A border commission was set up in 1966 with representatives from Guyana, Venezuela and the United Kingdom, but failed to reach agreement. Venezuela vetoed Guyana's bid to become a member of the Organization of American States (OAS) in 1967. In 1969 Venezuela backed an abortive uprising in the disputed area.
