AKP Phnom Penh, January 02, 2026 --

Cambodia will not recognise any alteration of the international boundary resulting from the use of force, and any actions deviating from the consensus outlined in the Joint Statement of Dec. 27, 2025, as well as previous agreements, constitute unlawful acts and violations of the ceasefire agreement.

This firm position was reiterated this morning by H.E. Pen Bona, Head of the Royal Government Spokesperson Unit, during a press briefing.

The spokesperson underscored the Royal Government’s unwavering commitment to safeguarding the Cambodia-Thailand international boundary as inherited from the Commission for the Delimitation of the Boundary between Indochina and Siam, in full respect of international law. This includes adherence to the principle of the intangibility of frontiers (uti possidetis juris), the Franco-Siamese conventions and treaties, the maps, and the procès-verbaux of the Commission of the Abornement of the Boundary between Indo-China and Siam, as well as all relevant agreements and documents mutually agreed upon by both parties.

He further referred to Point 3 of the Joint Statement of the 3rd Special General Border Committee (GBC) Meeting, adopted and signed by Cambodia and Thailand on Dec. 27, 2025, which states:

“Both sides agree that all arrangements under this Joint Statement are without prejudice to the border demarcation and international boundary between the two countries. Both sides agree to refer to the Joint Boundary Commission to resume, at the earliest, the survey and demarcation works, in accordance with existing agreements between the two countries to achieve lasting peace along the border. Both sides agree to utilize Joint Boundary Commission’s existing mechanisms to ensure safety and security of the joint survey team on the ground, including its safety from landmines. Both sides agree that the Joint Boundary Commission will accord the first and foremost priority for the immediate survey and demarcation works in the affected border areas where the civilians resided.”
