The temporary reference marking along the Thai–Cambodian border between boundary posts 52 and 59 has been successfully completed, covering a distance of 8.3 kilometers in Pong Nam Ron District, Chanthaburi. The operation was finished after 16 days of joint fieldwork, marking a significant step in developing shared reference data for both nations. A total of 166 temporary reference markers were installed by the Thai–Cambodian joint survey team, forming the basis for further technical assessment and cooperation.

Royal Thai Navy spokesperson Rear Admiral Parach Rattanachaiyaphan confirmed the completion of the survey and marking process on 26 November 2025. The mission was conducted to establish mutually agreed geographic information and was not designed to alter the existing border. Authorities emphasized that the activity represents a technical phase under internationally recognized standards agreed by both sides.

The survey forms part of broader cooperation between Thailand and Cambodia on border management, overseen through established bilateral mechanisms. The work was carried out under the framework of the Regional Border Committee (RBC) to maintain order and ensure safety throughout the operation. The Chanthaburi Marine Special Task Force, operating under the Chanthaburi and Trat Border Defense Command, supported the mission with caution and coordination

Officials stressed that the installation of temporary markers does not constitute a change to territorial lines or sovereignty. Instead, the markers serve as reference points to support accurate mapping and shared understanding of terrain. Rear Admiral Parach reiterated that the process aims to strengthen cooperation rather than redefine any border at this stage.

Once the data from the survey is processed, the next step will involve aerial drone photography to produce high-resolution mapping information. All collected material will be submitted to the Joint Boundary Committee (JBC) chairpersons from both countries for formal consideration and approval. Only after this endorsement will Thailand enter discussions with Cambodia on preparations for constructing a border fence.

Thaitabloid reported that stated that the proposed fence will act as a border management tool to enhance control of cross-border movement and prevent illegal activities, rather than serve as a new demarcation line. The Royal Thai Navy reaffirmed its commitment to protecting national sovereignty, safeguarding national interests, and ensuring the safety of communities in border areas. The mission marks continued progress in shared border administration between the two neighboring nations.

Success in the establishment of temporary reference markers along the Thai-Cambodian border (at Boundary Markers 52-59), a distance of 8.3 kilometers, in Pong Nam Ron District, Chanthaburi Province. Rear Admiral Parat Rattanachaiphan, Royal Thai Navy spokesman, stated that the survey and placement of temporary reference markers along the Thai-Cambodian border, at Boundary Markers 52-59, a distance of 8.3 kilometers, has been completed. The work took a total of 16 days. The Thai-Cambodian joint survey team has placed 166 temporary reference markers, marking significant progress in establishing shared reference data between the two countries. This survey is a technical process in accordance with international standards accepted by both countries to ensure consistent topographic information. The Royal Thai Navy confirmed that no border changes are being made at this stage. The next step is to conduct aerial drone surveys to produce highly detailed and accurate maps. All data will be compiled and submitted to the JBC Chairs of both countries for official approval. Once the data is certified, the Thai side will discuss with the Cambodian side to begin the preparation process for the construction of a border fence. This will enhance border control, prevent all illegal activities, and enhance clarity in joint area management. This fence serves as a border management tool. This is not a new border. The Chanthaburi and Trat Border Defence Command (CBT), through the Chanthaburi Marine Task Force, has carefully carried out this mission under the cooperation mechanism of the Regional Border Committee (RBC) to maintain peace and order and the utmost safety for the survey team. The Royal Thai Navy confirms that it will protect national sovereignty, preserve national interests, and ensure the safety of the people in the border areas with full force.
