Phnom penh: Cambodia has proposed holding an urgent and special meeting of the Cambodia-Thailand Joint Land Border Demarcation Commission (JBC) during the first week of January 2026 in Siem Reap to discuss and continue the work of topographic surveys and land border demarcation. This proposal was conveyed to the Thai side via a diplomatic note, according to a press release issued this morning by the State Secretariat for Border Affairs (SSBA).
According to Agence Kampuchea Presse, the Cambodian JBC has proposed to resume the work of topographic surveys and installation of temporary markers in the field, between border markers No. 42 and 47, located in the villages of Chouk Chey and Prey Chan, commune of O' Beichoan, district of O' Chrov, province of Banteay Meanchey, as well as between border markers No. 52 and 59, located in the communes of Boeung Reang and Kamrieng, district of Kamrieng, province of Battambang.
Furthermore, the Cambodian JBC proposed to initiate discussions regarding topographic surveys and the installation of temporary boundary markers in the field, between border markers No. 33 and 37 (Boeung Trakuon sector), the ThmSr Da international border post (Thm Da commune, Veal V¨ng district, Pursat province), the O' Phluk Damrei border area (Thm Da commune), the Chor I border area (Thm Da commune) and other border areas.
The Cambodian JBC also requested the dispatch of joint teams of surveyors to carry out topographic surveys and demarcation work on the ground situated between the exact agreed locations of the boundary markers (the watercourse and the straight demarcation line), in accordance with the spirit of the minutes of the 6th JBC Meeting, dated June 15, 2025, in Phnom Penh.
The SSBA took this opportunity to reaffirm that the Cambodian JBC firmly maintains its position regarding the safeguarding of the Cambodia-Thailand international border, as inherited from the border demarcation commissions between Indochina and Siam, in full respect of international law, the principle of the inviolability of borders (uti possidetis juris), the Franco-Siamese conventions and treaties, the maps and minutes of the border demarcation commission between Indochina and Siam, as well as all relevant mutually agreed agreements and documents.
In this regard, the Cambodian JBC will continue, as soon as possible, the work of topographic surveys and demarcation of the border with the Thai JBC, with a view to establishing a lasting peace along the border, and will not recognize any modification of the demarcation line resulting from the use of force.
The SSBA also called on its compatriots and the general public to place their full trust in the Royal Government of Cambodia and the Cambodian JBC, which consistently uphold the highest standards of professionalism and responsibility, and systematically place the supreme national interest first, particularly with regard to safeguarding territorial integrity and national sovereignty.
