Thailand and Cambodia signed a ceasefire agreement on Sunday in the presence of U.S. President Donald Trump, who had mediated in July to end a five-day border conflict that claimed lives.

The agreement was signed by Cambodian Prime Minister Hun Manet and Thai Prime Minister Anutin Charnvirakul, along with Trump, who was visiting the Malaysian capital for a day to attend the ASEAN summit before heading to Japan and South Korea.

The signing took place shortly after Trump’s arrival in Kuala Lumpur, the first stop of his Asian tour, during which he is also scheduled to meet Chinese President Xi Jinping.

This agreement follows a truce reached three months ago after Trump called both leaders, urging them to halt hostilities or risk suspension of trade talks with Washington.

The border dispute erupted in July and escalated into the most intense military clashes between the two nations in decades, resulting in over 40 deaths and forcing around 300,000 people to flee.

After five days of fighting, both sides agreed to a ceasefire brokered in part by Trump. However, since then, they have continued to exchange accusations of violating the truce.
