The leaders of Thailand and Cambodia are set to attend mediation talks in Malaysia next Monday as escalating border clashes leave more than 30 people dead and over 200,000 displaced. The Malaysian-mediated talks, due to begin at 3 p.m. local time (0700 GMT), will be led by Thailand’s Acting Prime Minister Phumtham Wechayachai, while Cambodian Prime Minister Hun Manet is also confirmed to attend.

The violence reignited on July 24, following a landmine incident that revived tensions from a smaller skirmish in late May that killed a Cambodian soldier. It has since become the most severe fighting between the two countries in over a decade, with both sides trading accusations of initiating hostilities and shelling civilian areas and historic temples like Preah Vihear and Ta Moan Thom.

The U.S. has weighed in strongly. President Donald Trump urged an immediate ceasefire and warned that continued conflict could jeopardize future trade deals. Secretary of State Marco Rubio separately called both foreign ministers, urging de-escalation and offering future U.S. support in diplomacy.

Thailand had earlier resisted third-party mediation—even from ASEAN, the U.S., or China—preferring bilateral talks and conditioning future negotiations on a cessation of fighting by Cambodia. With Malaysia now hosting the talks and both leaders present, hopes are rising that the violence may soon end.
