In a significant diplomatic development, the leaders of Thailand and Cambodia inked an expanded ceasefire agreement on Sunday, October 26, 2025, during the Association of Southeast Asian Nations (ASEAN) summit in Kuala Lumpur. The signing ceremony took place shortly after the arrival of US President Donald Trump, who played a pivotal role in mediating the cessation of a deadly five-day border conflict between the two nations in July 2025. This enhanced deal builds upon a truce brokered three months prior, when Trump intervened by urging the then-leaders of Thailand and Cambodia to halt hostilities, warning that continued conflict could jeopardize their respective trade negotiations with the United States. The presence of Trump at the signing underscored the US administration’s commitment to fostering stability in Southeast Asia. The agreement marks a critical step toward de-escalating tensions in the region and reaffirms the importance of diplomatic efforts in resolving conflicts.
