Guyana is in border disputes with both Suriname, which claims the area east of the left bank of the Corentyne River and the New River in southwestern Suriname, and Venezuela which claims the land west of the Essequibo River, once the Dutch colony of Essequibo as part of Venezuela's Guayana Essequiba. The maritime component of the territorial dispute with Suriname was arbitrated by the United Nations Convention on Law of the Sea, and a ruling was announced on 21 September 2007. The ruling concerning the Caribbean Sea north of both nations found both parties violated treaty obligations and declined to order any compensation to either party.
