Cambodia and Thailand on Sunday signed an expansion of a ceasefire that US President Donald Trump helped broker this summer to end their border conflict.
Trump used the threat of higher tariffs against both countries to help get them to agree to end the fighting that resulted in dozens of deaths and the displacement of hundreds of thousands.
The US leader watched as Cambodian Prime Minister Hun Manet and Thai Prime Minister Anutin Charnvirakul signed the expanded ceasefire at the annual summit of the Association of Southeast Asian Nations (ASEAN), of which both nations are members.
The agreement included Thailand releasing 18 Cambodian soldiers held prisoner and for both sides to begin removing heavy weapons from the border area.
Territory along the 800-kilometre frontier between Thailand and Cambodia has been disputed for decades, but previous confrontations were limited and brief.
