KUALA LUMPUR — Malaysia and the United States are working to broaden the ceasefire between Thailand and Cambodia, with hopes of formalizing an expanded agreement at the upcoming ASEAN summit from October 26–28, Malaysia’s Foreign Minister Mohamad Hasan said Tuesday.

The two countries fought a five-day conflict in late July, leaving dozens dead and over 260,000 displaced. A temporary ceasefire was brokered after mediation by Malaysia’s Prime Minister Anwar Ibrahim and pressure from U.S. President Donald Trump, who threatened to withhold trade privileges.

Despite the truce, tensions remain high. Thai soldiers were injured by landmines in August while patrolling a buffer zone, with Thailand accusing Cambodia of violating the ceasefire, a claim Phnom Penh denies.

Negotiations aim to expand the truce to include landmine clearance, withdrawal of heavy weapons, and improved management of sensitive border areas. Thailand has set four conditions for Phnom Penh: remove heavy weapons, clear mines, curb cross-border crime, and manage sensitive zones.

Trump is expected to attend the ASEAN summit in Kuala Lumpur and may witness the signing of the Kuala Lumpur Accord between Thailand and Cambodia. ASEAN comprises Brunei, Cambodia, Laos, Indonesia, Malaysia, Myanmar, the Philippines, Thailand, Vietnam, and Singapore.
