Cambodia's government has filed notice under a U.N. agreement on maritime law for compulsory conciliation of a sea border dispute with neighboring Thailand, Prime Minister Hun Manet said Tuesday.
At issue is territory claimed by both that is believed to contain large, exploitable amounts of natural gas and other hydrocarbons.
The decision to take the matter to the the U.N. Convention on the Law of the Sea, or UNCLOS, comes after Thailand last month terminated a 25-year-old memorandum of understanding with Cambodia meant to resolve overlapping maritime claims.
