President Donald Trump will oversee the signing of a peace accord between Thailand and Cambodia during his visit to Malaysia for the 47th ASEAN summit. The US president has publicly taken credit for brokering what he calls a “great peace deal” aimed at resolving a territorial conflict that has persisted for generations.
The peace process was initiated after violent border clashes erupted in July 2025 between Thai and Cambodian forces along their disputed frontier. The five-day military confrontation resulted in fatalities and displaced thousands of civilians on both sides of the border, creating an urgent humanitarian situation that required immediate international attention and mediation.
Malaysia emerged as the key mediator in the conflict and successfully negotiated a ceasefire that was implemented in late July 2025, effectively ending 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 nations comply with the terms of the cessation of hostilities.
While aboard Air Force One, President Trump announced via Truth Social that the peace deal signing would take place immediately upon his arrival in Malaysia to accommodate all the world leaders and officials attending this historic diplomatic event. Trump also expressed condolences for the death of Thailand’s Queen Mother and stated he would meet with Thailand’s Prime Minister upon landing. The ceremony will be witnessed by Malaysian Prime Minister Anwar Ibrahim and other ASEAN leaders.
The peace accord represents the culmination of months of diplomatic work, including recent breakthroughs achieved 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. 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 stated that both sides are moving closer to finalizing a Declaration of Thailand-Cambodia Relations designed to permanently resolve border issues. The territorial dispute has historically centered on competing claims to ancient Hindu temple sites 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.
