Thailand Ends 2001 Maritime Agreement with Cambodia

Apr 26, 2026, 21:20

Introduction

The Thai government has announced that it is ending the 2001 memorandum of understanding (MoU 44) regarding overlapping maritime claims with Cambodia. The government is now shifting its focus toward resolving land border disputes.

Main Body

The decision to cancel MoU 44 comes after twenty-five years of little progress and increasing pressure from within the country. Deputy Prime Minister and Foreign Minister Sihasak Phuangketkeow emphasized that this was a sovereign decision and was not influenced by external parties, such as China. Instead of the old agreement, the government plans to use the United Nations Convention on the Law of the Sea (UNCLOS) as the main legal framework for future talks. Thailand will formally notify Cambodia of this decision to see how they respond. Regarding security, the Royal Thai Navy asserted that the end of MoU 44 will not weaken maritime security or the protection of national borders, as the agreement was only a guide for negotiations. Furthermore, the government claimed that legal experts were consulted to ensure the move follows international law. Democrat leader Abhisit Vejjajiva supported this view, criticizing the original MoU as ineffective due to errors in the maps, provided that the new process follows legal principles. From an economic and diplomatic perspective, the government admits that ending the agreement might delay the extraction of energy resources in disputed waters. As a result, Thailand is looking for alternative energy sources in Myanmar, Central Asia, Africa, and the Gulf Cooperation Council. Diplomatically, Thailand emphasized that mutual trust is necessary before starting new talks. While Cambodia has suggested using the Joint Boundary Commission (JBC) and China has offered to help, Thailand clarified that any external involvement would not be considered interference in their bilateral process.

Conclusion

Thailand has moved from the MoU 44 framework to a UNCLOS-based approach for maritime claims. The country is now prioritizing land border issues and alternative energy sources while waiting for a diplomatic response from Cambodia.
