Phnom penh: 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.

According to Agence Kampuchea Presse, 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 proc¨s-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 that both sides agree all arrangements under the statement are without prejudice to the border demarcation and international boundary between the two countries. Both sides have agreed 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. They also agreed to utilize the Joint Boundary Commission's existing mechanisms to ensure safety and security of the joint survey team on the ground, including its safety from landmines. Additionally, both sides agreed that the Joint Boundary Commission will prioritize immediate survey and demarcation works in the affected border areas where civilians reside.
