United States President Donald Trump will formalize peace stability between Thailand and Cambodia during his visit to Malaysia for the 47th ASEAN summit. The president has described himself as the proud broker of this “great peace deal” that aims to establish lasting stability in the region.
The peace stability responds to violent border clashes that erupted in July 2025 between Thai and Cambodian forces along their disputed frontier. The five-day confrontation resulted in loss of life and displaced thousands of civilians on both sides, underscoring the urgent need for a stable, long-term diplomatic solution to prevent future conflicts.
Malaysia played a key mediating role and successfully negotiated a ceasefire that 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.
President Trump announced via Truth Social while aboard Air Force One that the peace stability formalization would occur immediately upon his arrival in Malaysia. This expedited schedule is designed to accommodate the numerous international leaders attending this significant event, including Malaysian Prime Minister Anwar Ibrahim and other ASEAN leaders. Trump also expressed condolences for the recent passing of Thailand’s Queen Mother and stated he would meet with Thailand’s Prime Minister shortly after landing.
The formalized peace stability 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 indicated 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 violence in 2011 near Preah Vihear temple resulting in at least 16 deaths.
