Both countries' foreign ministers agreed that no other country should be involved in the issue, Mohamad Hasan said.

"I made it clear to [Trump] that Cambodia agreed with the proposal for an immediate and unconditional ceasefire between the two armed forces," Cambodian PM Hun Manet said after the phone call, adding that Trump's mediation "will truly help protect the lives of many soldiers and civilians".

Trump posted on Truth Social on Saturday that he spoke to the leaders of Thailand and Cambodia and suggested he would not move forward with trade agreements with either country if the hostilities continued.
