US President Donald Trump has announced that the prime ministers of Thailand and Cambodia will stop fighting "effective this evening." The announcement came after Trump spoke to the two leaders following recent deadly border clashes. At least 20 people have died and around half a million have been displaced in the conflict. Nor Thai Prime Minister Anutin Charnvirakul nor Cambodian Prime Minister Hun Manet has officially commented yet. However, after his call with Trump, Anutin said a ceasefire would only happen if "Cambodia will cease fire, withdraw its troops, remove all landmines it has planted." Trump posted on his social media platform Truth Social, stating, "Both leaders have agreed to CEASE all shooting effective this evening, and go back to the original Peace Accord made with me. Both Countries are ready for PEACE and continued Trade with the United States of America." The conflict began on 24 July, when Cambodia fired rockets into Thailand. Thailand responded with air strikes. Days of fighting left dozens dead. Trump and Malaysian Prime Minister Anwar Ibrahim brokered an "immediate and unconditional ceasefire." Despite that, tensions grew, and violence spread to six provinces in north-eastern Thailand and five in Cambodia. The two countries have disputed their 800km land border for over a century, since border lines were set after French colonial rule in Cambodia.
