09 November 2025 – 10:10

Revealing a 5-step plan to build a Thai-Cambodian border fence, boundary markers 52–59 Chanthaburi-Trat, expected to take 15 days to put together temporary markers.

Progress in building the border fence Marine Corps Special Unit Area, Chanthaburi (Navy Task Force, Chanthaburi) in the supervision of the Chanthaburi and Trat Border Defense Command (Border Defense Command), Ministry of Foreign Affairs Both sides by the Thai side, Mr. Prasat Prasat Winitchai The head of the Joint Boundary Commission (JBC) signed and the Cambodian side Has considered certification of technical documents (Technical Instruction: TI)

For the survey and installation of temporary boundary markers between boundary markers 52–59, which are steps 1-2 already completed. In the next step, step 3 will be carried out, which is surveying the boundaries and setting up temporary boundaries. By making an appointment with the Cambodian side. Let's take action soon.

The first step is to recognize the authority framework according to the Thai-Cambodian Border Convention. Provincial border area Chanthaburi-Trad They must confirm that the main area 52–59 is the “Agreed Boundary Line”.

JBC has passed a resolution or issued a “Letter of Principles Approval” allowing the construction of a fence along the said line. Ready to appoint “Technical Sub-Committee” to control work at the practical level

Step 2: Have both sides prepare a revised Technical Instruction (TI) with the Royal Thai Survey Department. along with the joint Thai-Cambodian survey team, taking the original TI (which the survey team had already signed) and adjusting the message to make it clear that Temporary exploration and settlement is only for Place the fence only along the straight line between the agreed-upon boundary markers.

Step 3 is surveying the boundaries and setting up temporary boundaries. by the Thai-Cambodian joint survey team Use GPS/GNSS satellite surveying tools, RTK and Total Station techniques to confirm the boundary line is a straight line. Between boundary markers 52–59

Along with setting up temporary markers (Temporary Markers)” every 50–100 meters to use as a reference line along the boundary. Flying aerial photographs with an unmanned aerial vehicle (Drone) to use as supporting information in making diagrams.

along with preparing a field map which includes information on the location of boundary markers 52-59, temporary marker locations and aerial photographic information according to the scale agreed upon by both sides

Then prepare a report of the survey results and temporarily pin it. between boundary markers 52-59 along with a field map and account for the temporary pin coordinates between main points 52-59. Then prepare a report of the results for OG JTSC and JBC to consider and certify.

For the “actual boundaries in the field” that have been accepted by both countries The boundaries are clear. Reduce the problem of confrontation between forces on both sides. and use it as a reference line for building fences

Currently both Thailand and Cambodia We have reached step 3 in exploring and pinning together. It is expected that it will take approximately 10-15 days, depending on the conditions in each area and the main area. Some areas are flat areas. Some areas are high areas. And also have to be careful about landmines that may remain in the area. Therefore, there must be military engineering units from both countries to lead the way in setting up the markers first.

Then, step 4 is preparation and signing. “MOU on Border Fence Construction with responsible agencies such as the Ministry of Defence/Navy/JBC in collaboration with the Ministry of Interior. All of the information that both parties agree on from steps 1-3 must be taken to prepare a draft MOU to prevent illegal logging, logging, and illegal transportation. “Border crossing control fence” is not a “new border line”

for maintenance leaks Must be jointly supervised by the Regional Border Committee (RBC), submitting a proposal through the Ministry of Foreign Affairs for JBC to certify before actually signing.

Then document the state-to-state agreement (MOU) certifying the construction of the fence. Operate correctly in accordance with the 1907 Border Convention and the 2000 MOU.

Step 5: Conduct construction and joint inspection. In the Chanthaburi-Trad border area Unit of primary responsibility for the Navy (PROC/Chanthaburi Marine Task Force/Thai-Cambodian Joint Construction Unit) The border fence was built correctly according to legal procedures, is safe, and has been accepted by both countries.
