The action also violated Article 5 of the Memorandum of Understanding between the Cambodian and Thai governments on the Survey and Demarcation of Land Boundary, signed on June 14, 2000, as well as Point 1 of the Joint Statement of the Third Special Meeting of the General Border Committee (GBC), dated December 27, 2025, the ministry noted.

“Cambodia categorically rejects any unilateral border line or territorial claim by Thailand, and the aforementioned [Thai violations] do not affect Cambodia’s legitimate rights or position concerning its international borders,” it added.

The Cambodian government demanded that Thailand “immediately cease all such illegal activities, stop all unilateral actions, and work to ease tensions, build mutual trust, and maintain peace and good neighbourly relations along the border between the two countries”.
