Cambodia Stands Firm on Borders as Ceasefire with Thailand Takes Effect

PHNOM PENH, Jan 25, 2026 (KPT) – Cambodia has reaffirmed its commitment to a series of internationally backed ceasefire and peace agreements with Thailand, while insisting it will not accept any change to the two countries’ border resulting from the use of force.

Government spokesman Pen Bona said Phnom Penh would “fully, strictly and responsibly” implement all agreements reached with Bangkok, stressing that the Cambodia–Thailand boundary is defined by historical treaties and international law, including the principle of uti possidetis juris.

“Cambodia will not recognise any alteration of the boundary line resulting from the use of force,” he declared.

The accords were reached with the support of international partners, notably the United States, China and Malaysia, which chaired ASEAN in 2025.

An immediate and unconditional ceasefire took effect on July 28, 2025, following talks in Putrajaya chaired by Malaysian Prime Minister Anwar Ibrahim and attended by Cambodian Prime Minister Hun Manet and Thailand’s acting leader Phumtham Wechayachai.

The United States co-organised the meeting, with China actively participating, while Malaysia pledged to coordinate an ASEAN observer team to monitor compliance.

On October 26, 2025, Hun Manet and Thai Prime Minister Anutin Chanvirakul signed a joint peace declaration in Kuala Lumpur, witnessed by the US president and Malaysia’s prime minister.

Both sides vowed to refrain from force and settle disputes peacefully under international law, reaffirming commitments through the General Border Committee.

Further measures were agreed on December 27, 2025, at a GBC meeting held at the Pailin–Chanthaburi border crossing.

Cambodian Defence Minister Tea Seiha and his Thai counterpart Nattaphon Narkphanit announced a halt to troop deployments and patrols, and pledged to resume joint boundary surveys with safety guarantees for survey teams, including protection from landmines.

The joint statement also guaranteed safe and dignified return for civilians displaced by border tensions.

Cambodia reiterated it would safeguard the frontier as defined by Franco-Siamese treaties, maps and official records, and uphold all agreements reached with Thailand.
