Thailand has agreed to participate in a UN arbitration process initiated by Cambodia to resolve a long-standing maritime boundary dispute in the Gulf of Thailand. This decision comes after Cambodia launched a compulsory conciliation process under the UN Convention on the Law of the Sea (Unclos). Thailand had previously ended a 2001 framework pact for bilateral talks on the contested maritime area. The dispute concerns approximately 26,000 sq km of sea, believed to contain significant natural gas and oil reserves valued at $300 billion. For now, Thailand is pausing other bilateral efforts to settle their contested borders.
