On October 2, Cambodia's Ministry of Foreign Affairs issued a statement saying that on September 30, Thai soldiers, accompanied by monks, raised the Thai national flag in the area of the Thmar Da international checkpoint in Thmar Da commune, Veal Veaeng district, Pursat province. Cambodia considers this act an infringement on its sovereignty and territorial integrity and has once again lodged a protest with Thailand.
The ministry stated that, based on the 1904 Franco-Siamese Convention, the 1907 Treaty and related boundary maps, Cambodia determined that the area in question belongs to Cambodian territory, and considered the Thai action to be in violation of the memorandum of understanding on the survey and demarcation of the land boundary signed by the two countries in 2000.
The statement also noted that Cambodia considered the act inconsistent with the ceasefire and de-escalation arrangement reached between Cambodia and Thailand on December 27, 2025. Cambodia reiterated that it does not recognize any boundary line or territorial claim unilaterally put forward by Thailand.
The Cambodian government demanded that Thailand stop the relevant action, refrain from further unilateral measures, and take concrete steps to reduce border tensions and promote mutual trust between the two sides.
Cambodia also stressed that the action would not affect its legal rights and existing position on international boundary issues, and said it would continue to handle border disputes in accordance with international law and existing agreements between the two countries.
The Ministry of Foreign Affairs reiterated that Cambodia advocates a peaceful resolution of border issues with Thailand and other neighboring countries, and insists that international borders should not be altered by force. Cambodia has also recently protested to Thailand over activities in the Thmar Da area.
