A territorial dispute between the two South Asian nations escalated into armed clashes earlier this year

Cambodia and Thailand have signed an extended ceasefire to end a deadly border clash that erupted earlier this year. The signing ceremony on Sunday was overseen by US President Donald Trump, who brokered the initial truce.

Longstanding tensions between the two Southeast Asian neighbors rooted in colonial-era border disputes erupted in July as both sides traded fire for five days and hundreds of thousands fled the border area. A Malaysia-hosted meeting then produced a truce - the first step toward ending the crisis. Trump later said he used trade talks with both nations to push for de-escalation.

Cambodian Prime Minister Hun Manet and Thai Prime Minister Anutin Charnvirakul signed the expanded ceasefire on Sunday at the 47th ASEAN summit in Malaysia.

Building on July's truce, it sets a framework to ease tensions and secure lasting peace along the border. The deal calls for Thailand to release 18 captured Cambodian soldiers, both sides to withdraw heavy weaponry, begin demining, and curb illegal cross-border activities.

Following the signing, the Thai prime minister said border weapon withdrawals would begin "promptly," alongside the release of Cambodian POWs, and announced a joint trade framework. His Cambodian counterpart praised the deal and vowed to uphold it, thanking Trump for his role. He added that he had nominated the US president for next year's Nobel Peace Prize.

The US president hailed the deal as "monumental" and "historic." He also highlighted his own role in the agreement, telling reporters he was very good at making "peace deals" and that it was "almost a hobby." After the ceremony, Trump signed a reciprocal trade deal with Cambodia and a critical minerals agreement with Thailand.

Since returning to office, Trump has repeatedly claimed he deserves the Nobel Peace Prize for resolving various conflicts across the globe. He cited his Gaza peace plan as his eighth such success but has at times confused his record, falsely claiming to have settled nonexistent disputes between Albania and Azerbaijan and between Armenia and Cambodia. He nevertheless welcomed this year's award going to Venezuelan opposition leader Maria Corina Machado, congratulating her and noting his past support for her cause.
