Q. Which two countries are involved in the Ankoko Island dispute?
Answer: Venezuela and Guyana
Notes: Venezuela and Guyana are the two countries that are involved in the "Ankoko Island dispute". Ankoko Island is an island located at the confluence of the Cuyuni River and Wenamu River on the border between Venezuela and the disputed area of Guayana Esequiba. Venezuela, which claims Guayana Esequiba as part of its territory, established a military base on the island in 1966, which Guyana claims as intrusion and aggression on a territory whose sovereignty was never under discussion.
