Cambodian–Thai joint survey teams are measuring and searching for the exact locations of 74 concrete border markers installed by the Indochina–Siam marker commission in 1919–1920, according to Cambodia’s State Secretariat of Border Affairs. The work includes markers 42–47. The statement followed agreement to use drones for aerial mapping and install temporary markers on the ground in Chouk Chey and Prey Chan villages, Ou Beichoan commune, Ou Chrov district, Banteay Meanchey province. In a November 21 release, the secretariat said joint teams had undertaken fieldwork since 2006, based on legal documents inherited from the French protectorate, particularly marker records (Procès Verbaux) of the 1908–1909 Indochina–Siam boundary commission and the 1919–1920 marker commission. Between markers 42 and 47, the two sides had not previously carried out demarcation on the ground, only work to locate the markers accurately. Since November 18, 2025, both sides had continued step by step, agreeing to send teams to plan and carry out surveying and temporary-marker installation between markers 42–47 in that area, towards eventual ground demarcation. The work follows the 2000 MOU, 2003 terms of reference, previous Joint Boundary Commission (JBC) minutes and technical instructions agreed by both sides. The secretariat pledged professionalism and the highest responsibility in safeguarding national interests, territorial integrity and sovereignty, respecting international law, the inviolability of borders and the Cambodia–Thailand international boundary inherited from the Indochina–Siam boundary commissions. It urged the public to trust Cambodia’s government and its Joint Boundary Commission. Preah Sihanouk Provincial Television.
