United States President Donald Trump will oversee the signing of a peace agreement between Thailand and Cambodia in Malaysia, marking what he describes as a major diplomatic achievement. The president announced the signing ceremony while traveling to the 47th ASEAN summit, where he will also meet with Chinese President Xi Jinping.
The peace deal comes after violent clashes erupted between Thai and Cambodian forces in July 2025 over disputed border territories. The five-day military confrontation claimed lives and forced thousands of residents to evacuate their homes, creating an urgent humanitarian situation that demanded immediate international intervention and mediation.
Malaysia successfully mediated a ceasefire between the two nations, which was implemented in late July 2025 and brought an end to the active fighting. The Malaysian government has maintained its peacekeeping role by coordinating ASEAN observer missions that continue to monitor the truce and ensure both Thailand and Cambodia adhere to the terms of the cessation of hostilities.
In a Truth Social post from Air Force One, President Trump announced that the peace deal signing would occur immediately upon his arrival in Malaysia to accommodate the large number of international dignitaries attending the event. Trump also expressed condolences for the passing of Thailand’s Queen Mother and stated he would meet with Thailand’s Prime Minister shortly after landing. Malaysian Prime Minister Anwar Ibrahim and other ASEAN leaders will witness the historic signing ceremony.
The peace agreement builds on recent diplomatic progress made during a two-day special meeting of the Cambodia-Thai Joint Commission on Demarcation for the Land Boundary held in Chanthaburi, Thailand, on October 21-22. During these discussions, both nations reached several key agreements aimed at expediting the land demarcation process along their more than 800-kilometer shared border. Thailand’s Foreign Minister Sihasak Phuangketkeow has indicated that both sides are nearing completion of a Declaration of Thailand-Cambodia Relations designed to permanently resolve the border situation. The territorial dispute has historically focused on competing claims to ancient Hindu temples in the Dangrek Mountains, with the most serious previous incident occurring in 2011 when clashes near Preah Vihear temple resulted in at least 16 deaths.
