The latest round of the Thai-Cambodian Joint Boundary Commission (JBC) concluded after a marathon session that extended six hours beyond schedule, with both sides agreeing to repair damaged border markers and reassess land holdings in the contested Ban Nong Chan and Ban Nong Ya Kaeo areas of Sa Kaeo province.
The meeting also sidestepped discussions on border fencing, citing jurisdictional limitations.
The special session was co-chaired by Prasas Prasasvinitchai, the Thai ambassador to Cambodia, and Lam Chea, Cambodia’s minister in charge of border affairs.
The meeting officially concluded at 9pm but officials spent another three hours making extensive revisions to the wording of the minutes to ensure alignment with the positions of both nations. They were finally signed at 12.15am Thursday.
At the briefing that followed, Benjamin Sukanjanajtee, director-general of the Department of Treaties and Legal Affairs at the Thai Ministry of Foreign Affairs, described the discussions as candid and constructive.
Mr Benjamin noted that this was the first time the deliberations of the JBC had been made public, reflecting Thailand’s effort to reduce border tensions and prevent misunderstandings over sensitive issues.
Mr Prasas said the meeting proceeded in a friendly and cooperative atmosphere. Both sides assigned the Joint Technical Sub-Commission to reconstruct or replace 15 boundary markers that were damaged or missing, restoring them to their original locations. They also agreed to jointly determine new positions for three markers that were submerged.
Participants also agreed to expedite revisions to the 2003 terms of reference governing the creation of orthophoto maps. They will now incorporate technologies such as LiDAR (Light Detection and Ranging) to enhance the accuracy and efficiency of border mapping.
However, the issue of constructing a border fence was not discussed, as Cambodian co-chair Lam Chea said he had no authority over the matter.
The two sides also discussed the area between border markers 42 and 47, near Ban Nong Chan and Nong Ya Kaeo in Khok Sung district of Sa Kaeo province. The two villages have been the scene of a series of uneasy standoffs in recent weeks.
Both delegations agreed to hold technical consultations to facilitate temporary surveying and placement of provisional boundary markers in the area. These markers are intended solely for survey purposes and will not affect the legal territorial claims of either country under international law.
The two sides also pledged to instruct local military and civilian authorities to ensure the safety of demining teams operating in the area, in accordance with Article 3 of the 2000 Memorandum of Understanding (MoU). The goal is to allow survey operations to proceed without interference or provocation that could escalate tensions.
Mr Prasas said details of the resolutions would be submitted to the cabinet for consideration. He estimated the technical survey process would take at least six weeks to complete.
The next JBC meeting is scheduled to take place in Siem Reap, Cambodia, during the first week of January.
The JBC focuses on legal and technical land demarcation, led by foreign ministry officials. The GBC (General Border Committee) is for security issues and is chaired by defence ministers, and the RBC (Regional Border Committee) handles regional border management and cooperation, involving regional military commanders.
