Malaysia and the U.S. are supporting efforts to expand the ceasefire between Thailand and Cambodia, aiming for a signing at the upcoming ASEAN summit later this month, Malaysia’s Foreign Minister Mohamad Hasan said Tuesday.

The two countries fought five days of combat in late July, killing dozens and displacing over 260,000 people, and agreed to a truce after mediation by Malaysia’s Prime Minister Anwar Ibrahim and pressure from U.S. President Donald Trump, who threatened to withhold trade privileges.

Tensions have persisted, including land mine incidents in August, with Thailand accusing Cambodia of violating the truce—claims Phnom Penh denies.

Negotiations now focus on broadening the ceasefire to include land mine clearance, withdrawal of heavy weapons, and improved border management, the Associated Press has reported.

The expanded agreement, known as the Kuala Lumpur Accord, could be signed during the ASEAN summit in Kuala Lumpur from October 26–28, which Trump is scheduled to attend.
