President Donald Trump will solidify a peace resolution between Thailand and Cambodia at the Malaysian gathering, marking what he considers a significant diplomatic victory. The US president announced his participation while traveling aboard Air Force One to the 47th ASEAN summit in Malaysia.
The peace resolution comes after serious border clashes erupted in July 2025 between Thai and Cambodian military forces along their disputed frontier. The five-day military engagement resulted in loss of life and displaced thousands of civilians living near the border, underscoring the urgent need for a diplomatic solution to prevent further violence and humanitarian suffering.
Malaysia successfully intervened as a mediator and negotiated a ceasefire between the two nations, which was implemented in late July 2025. Since the truce took effect, the Malaysian government has coordinated ASEAN observer teams that remain deployed along the border to monitor compliance and ensure both Thailand and Cambodia honor the terms of the cessation of hostilities.
In a Truth Social post from Air Force One, President Trump announced that the peace resolution solidification would take place immediately upon his arrival in Malaysia to accommodate all the dignitaries attending this major diplomatic event. Trump also expressed condolences for the death of Thailand’s Queen Mother and confirmed he would meet with Thailand’s Prime Minister upon landing. Malaysian Prime Minister Anwar Ibrahim and other ASEAN leaders will witness the ceremony.
The solidified peace resolution addresses a territorial dispute spanning more than 800 kilometers of shared border between Cambodia and Thailand, including multiple non-demarcated areas. Recent diplomatic progress includes agreements reached during an October meeting of the Joint Commission in Chanthaburi, Thailand, where both nations committed to advancing boundary demarcation efforts. Thailand’s Foreign Minister Sihasak Phuangketkeow has stated that both countries are close to finalizing a Declaration of Thailand-Cambodia Relations designed to comprehensively resolve the border situation. The dispute has historically centered on ancient Hindu temple sites in the Dangrek Mountains, with previous serious violence in 2011 near Preah Vihear temple resulting in at least 16 deaths and UN Security Council involvement.
