Cambodia Protests Thai Construction in Border Area

Cambodia has formally protested to Thailand over the construction of Buddha statues and the installation of flagpoles in a disputed border area, escalating tensions along the Thai-Cambodian frontier. The Cambodian Ministry of Foreign Affairs and International Cooperation issued a statement on 30 May, alleging that the works violate a joint statement agreed on 27 December 2025.

According to Cambodian authorities, Thailand has continued activities in territory that Cambodia claims has been under illegal occupation by Thai forces since 27 December 2025. The latest protest concerns the construction of at least 36 Buddha statues in several locations within Preah Vihear and Oddar Meanchey provinces, as well as the installation of two flagpoles in Preah Vihear province.

The ministry stated that, following the ceasefire agreement of 27 December 2025, Thai forces had continued to strengthen their presence through the construction of permanent structures. These reportedly include roads, large Buddha statues, reinforced barriers using shipping containers and barbed wire, flagpoles in multiple locations, and cultural and tourism activities.

Cambodia argued that such actions cannot be regarded as measures to maintain military positions and instead contradict provisions contained in the joint statement issued after the third special meeting of the General Border Committee (GBC) on 27 December 2025. The statement specifically cited clauses two and three of the agreement.

The Cambodian government reiterated that it does not recognise any border demarcation established through force or any unilateral territorial claims made by Thailand. It further stated that the activities would not affect Cambodia’s legal rights or status concerning the international border between the two countries.

Cambodia called on Thailand to honour its commitments under the December 2025 joint statement in order to restore mutual trust and confidence, while promoting peace, stability and good neighbourly relations along the shared border.

The ministry highlighted two key provisions of the agreement. Clause two states that both sides agreed to maintain existing troop positions without further deployments and that neither side would conduct patrols into the other’s positions.

Clause three states that all agreements under the joint statement are without prejudice to the international border delimitation process. Both countries agreed to refer the matter to the Joint Boundary Commission for renewed surveying and border demarcation efforts, with priority given to affected border areas where civilians reside and with measures in place to ensure the safety and security of joint survey teams, including protection from landmines.

Amarin reported that the dispute is expected to remain under discussion through existing bilateral border mechanisms, particularly the Joint Boundary Commission, as both countries seek a longer-term resolution to the contested areas.
