Thailand’s military is pressing ahead with the construction of a new border fence along the Thai-Cambodian frontier in Chanthaburi province, covering the area between boundary markers 52 and 54 in Pong Nam Ron district. The project stretches approximately 1,310 metres and is intended to strengthen border security and improve safety for residents living near the frontier.

Security sources confirmed on 11 May 2026 that the work is taking place entirely within Thai sovereign territory. The area is described as flat terrain with clearly defined border lines, while both Thailand and Cambodia maintain patrol roads running alongside the frontier.
The structure is being built using reinforced materials designed to meet security standards. The fence will stand approximately 170 centimetres high, supported by concrete piles and beams, with each post spaced around three metres apart. Authorities estimate that between 900 and 1,000 posts will be installed during construction.
The upper section of the barrier will use prefabricated concrete panels positioned at ground level. An additional level of reinforced steel mesh will be installed on top to improve durability and support border monitoring operations.
Security sources said some difficulties had emerged during construction after Cambodian soldiers were seen observing and photographing the work. Thai officials maintained that all activities are being conducted within Thailand’s recognised territory and described the project as part of the country’s right to manage and protect its own borders.

The first phase of the project is expected to be completed within 45 days. Construction reportedly began in late April 2026 and is continuing daily as military engineers work to meet the target deadline.
Thai officials stated that the fence is intended not only as a physical barrier but also as a symbol of the military’s commitment to protecting national sovereignty. Authorities added that the project aims to reassure communities living along the border and contribute to long-term peace and security in the region.
Naewna stated that reports also indicated that images of the construction site, recorded by Cambodian soldiers, have been widely circulated on Cambodian Facebook pages and other social media platforms. The photographs have attracted significant attention online as the project continues.
