ASEAN, Cambodia Monitor Thai Border Area

A joint delegation of Cambodian officials and ASEAN observers inspected a contentious border area between Thailand and Cambodia on Sunday. The visit, conducted by the Cambodian Liaison Group and led by the Philippines, aimed to monitor the border situation at Seila Khmer Village in Banteay Meanchey Province. This inspection comes after a ceasefire agreement between the two countries in December 2025, following increased tensions.

Cambodia asserts that the area in question has been under its administration since the ceasefire began. The inspection was intended to evaluate adherence to stabilization measures agreed upon in the ceasefire. The Cambodian Ministry of National Defense emphasized that only the Joint Boundary Commission and Joint Survey Teams are authorized to conduct formal boundary demarcations.

The Ministry rejected any unilateral boundary changes, stressing adherence to historical agreements like the Franco–Siamese conventions and the MOU of 2000. Cambodian officials urged Thailand to continue its boundary demarcation efforts and requested an immediate meeting of the Joint Boundary Commission.

Looking forward, Cambodia reaffirms its dedication to peaceful resolutions as outlined in the Joint Declaration from October 2025 and the border committee's resolutions from December 2025. These actions aim to secure long-lasting peace and stability along the border.
