Cambodia and Thailand have agreed on four points regarding the issues related to joint survey and demarcation in the segment of Boundary Pillars No. 42 to 47 in the area of Chouk Chey-Nong Chan Village and Prey Chan-Nong Ya Kaeo Village.
The agreement was reached during the Special Meeting of the Cambodian-Thai Joint Commission on Demarcation for Land Boundary (JBC), which is concluded around midnight on Oct. 22 in Chanthaburi province. The Cambodian side was led by H.E. Lam Chea, Minister in charge of the State Secretariat of Border Affairs of the Kingdom of Cambodia, Co-Chairman of the Cambodian-Thai JBC, while the Thai side was headed by H.E. Prasas Prasasvinitchai, Advisor to the Ministry of Foreign Affairs of the Kingdom of Thailand, Co-Chairman of the Thai-Cambodian JBC.
According to a press statement released after the meeting, both sides agreed to finalise the Technical Instruction (TI) for Joint Survey and Emplacement of Temporary Markers of priority terrain segments from Boundary Pillars No. 42 to 47.
After the completion of the survey and emplacement of temporary markers and approval by the respective governments, both sides will consult their respective governments to decide on any appropriate mechanism for the adjustment of land occupation of both sides.
They also agreed that the emplacement of temporary markers is for survey purposes only and shall be without prejudice to the international boundary between Cambodia and Thailand.
Moreover, they agreed to impress upon local authorities, both military and civilian to ensure the safety of the Joint Survey Team and not to obstruct its work, and to refrain from any act of provocation that create further tension within the areas and shall first be assured of its safety from landmines pursuant to the Article 3 of the MOU 2000.
For other border areas, both sides assigned the Joint Technical Sub-Committee (JTSC) to replace 15 Boundary Pillars which they agreed on the location to their original locations and specifications; and will replace 3 Boundary Pillars submerged in water at a position to be agreed upon by both sides.
They also agreed to accelerate the revision of Terms of Reference (TOR) 2003 regarding the production of orthophoto maps (Point 4, Step 2 of TOR 2003) by utilising new technologies such as LiDAR (Light Detection and Ranging) to expedite the survey and demarcation work.
The next Meeting of the JBC will be held in the first week of January 2026 in Siem Reap, Cambodia.
