AKP Phnom Penh, April 07, 2026 --

Cambodia has once again called on Thailand to convene an urgent meeting of the Joint Boundary Commission (JBC) and resume long-delayed border demarcation activities, according to a statement from the State Secretariat of Border Affairs.

The Cambodian side of the JBC said it had repeatedly sent diplomatic notes to its Thai counterpart requesting a special meeting, but the requests were postponed by Thailand, citing the need to complete internal procedures following the formation of its new cabinet.

In its latest Note Verbale dated April 7, Cambodia proposed holding a special JBC meeting in Siem Reap between April 17 and 22, 2026, in line with previous agreements reached during a special session in Thailand’s Chanthaburi province in October 2025.

Cambodia also proposed deploying Joint Survey Teams (JSTs) from both countries between April 20 and 24 to resume fieldwork, including surveying and placing temporary boundary markers along several disputed segments. These include boundary segment between Boundary Pillars No. 42-47 in Chouk Chey and Prey Chan villages, O’Chrov district, Banteay Meanchey province, and the segment between Boundary Pillars No. 52-59 in the Kamrieng district, Battambang province, in accordance with all previous agreements.

Additional proposals include conducting surveys and installing temporary markers in key border areas such as Boeung Trakuon, O’Smach, An Seh, and Thmar Da, as well as continuing demarcation work along agreed boundary lines, including river and straight-line segments.

Cambodia further suggested convening the 12th Cambodian-Thai Operational Group meeting and the 5th Joint Technical Sub-Commission meeting in the first week of May 2026 to advance technical discussions.

At the same time, the Cambodian side reaffirmed its firm stance against the illegal occupation of its territory by Thai armed forces and any actions that violate Cambodia’s sovereignty and territorial integrity. It rejected any attempt to alter the boundary line through the use of force.

The statement underscored Cambodia’s commitment to upholding internationally recognised borders based on historical treaties, including the Franco-Siamese agreements, as well as principles of international law such as uti possidetis juris. Cambodia also reaffirmed adherence to all mutually agreed documents and demarcation records between the two countries.
