Thailand’s Prime Minister Anutin Charnvirakul and Cambodia’s Prime Minister Hun Manet have signed an expanded ceasefire agreement in the presence of U.S. President Donald Trump. The signing took place on Sunday (October 26) on the sidelines of the ASEAN Summit in Kuala Lumpur, Malaysia, according to a report by Reuters.
Trump applauded the signing, while Malaysia’s Prime Minister Anwar Ibrahim — serving as ASEAN chair — also witnessed the ceremony.
The move marks another important step toward resolving the recent border conflict between the two Southeast Asian neighbors. The agreement was finalized shortly after Trump’s arrival at the summit.
Thailand and Cambodia have long been at odds over their 817-kilometer shared border — a dispute stretching back more than a century. Most recently, the tensions escalated into a fierce military clash on July 24.
Trump personally intervened at the end of July, calling the leaders of both countries to urge a ceasefire. He also warned that continued hostilities could jeopardize ongoing trade negotiations with the United States.
Diplomatic sources say the revised ceasefire deal builds on an interim understanding reached three months earlier. It includes provisions for joint border monitoring, reduced military deployments, and humanitarian access to conflict-affected areas.
Leaders of other ASEAN member states were also present during the signing. Analysts believe the agreement could be seen as another diplomatic success for the Trump administration in Southeast Asia.
The two countries have seen sporadic border clashes for decades — though the latest fighting was the most intense in 13 years.
