Kuala Lumpur Peace Accord

The Kuala Lumpur Peace Accord (officially the Joint Declaration by the Prime Minister of the Kingdom of Cambodia and the Prime Minister of the Kingdom of Thailand on the Outcomes of Their Meeting in Kuala Lumpur, Malaysia) was a peace agreement signed on 26 October 2025, on the sidelines of the 47th ASEAN Summit at the Kuala Lumpur Convention Centre in Kuala Lumpur, Malaysia.

The accord was reached in the aftermath of an escalating border crisis along the Cambodia–Thailand border, which had seen armed clashes, landmine incidents, and heightened military deployments on both sides. The crisis raised regional and international concerns about stability in Southeast Asia and underscored the urgency of diplomatic intervention.

In the declaration, Cambodian prime minister Hun Manet and Thai prime minister Anutin Charnvirakul affirmed their "unwavering commitment to peace and security between our two countries" and reiterated a pledge to "refrain from the threat or use of force, and to seek peaceful settlement of disputes."

The accord also outlined several concrete measures aimed at stabilizing the Cambodia–Thailand border region, including the establishment of an ASEAN Observer Team (AOT) to monitor the implementation of a ceasefire, the withdrawal of heavy weapons from border areas under observation, joint humanitarian demining operations, the restoration of confidence-building measures and diplomatic relations, and the prompt release of prisoners of war (POWs) by Thailand as a demonstration of goodwill.

The declaration was witnessed by Malaysian prime minister Anwar Ibrahim and United States president Donald Trump, underscoring regional and international support for the agreement. The accord marked a critical step toward de-escalating the border crisis and promoting long-term peace and stability between Thailand and Cambodia. However, clashes resumed between the two countries just two months later on 8 December.
