Regarding Thailand’s Acts of Aggression at Ta Tum and Chup Doeum Khnol Areas, Oddar Meanchey Province
23 July 2026

Q1: What is Cambodia’s position regarding Thailand’s activities at Ta Tum and Chup Doeum Khnol, Oddar Meanchey Province, between 13 and 19 July 2026?

A: Cambodia has lodged a formal protest against the actions of the Thai Armed Forces, which carried out land clearing for road construction and installed barbed wire in the Ta Tum and Chup Doeum Khnol areas of Oddar Meanchey Province. Cambodia considers these actions to constitute a clear violation of Cambodia’s sovereignty and territorial integrity, as well as a unilateral attempt to alter the status quo along the border.

Q2: What legal basis does Cambodia rely upon in protesting Thailand’s activities in these areas?

A: Cambodia’s protest is based on existing legal instruments and bilateral agreements between the two countries, including the Franco-Siamese Convention of 1904, the Treaty of 1907, and the 1:200,000 scale maps, which serve as the legal basis for the delimitation of the international boundary. Furthermore, Thailand’s actions are considered to violate Article 5 of the 2000 Memorandum of Understanding (MOU) and run contrary to the confidence-building measures set out in the Joint Statement of the 3rd Special Meeting of the General Border Committee (GBC) on 27 December 2025. Cambodia therefore maintains that these activities are inconsistent with international law and the bilateral agreements currently in force.

Q3: What measures is Cambodia requesting Thailand to take in relation to these recent encroachments?

A: Cambodia urges Thailand to immediately cease all land-clearing operations, road construction, barbed wire installation, and any other activities that alter the status quo in the border areas. Cambodia has also urged Thailand to end what Cambodia considers to be the unlawful occupation of the locations concerned and to comply with its obligations under the 2000 MOU, the Joint Statement of the 3rd Special Meeting of the General Border Committee (GBC) held on 27 December 2025, and international law. Cambodia emphasizes that these requests are intended to reduce tensions, restore mutual trust between the two sides, and create favorable conditions for the peaceful, sustainable resolution of border issues, thereby ensuring lasting peace along the shared border.
