President Donald Trump said Saturday that Cambodia’s prime minister and the acting prime minister of Thailand had agreed to meet immediately

Thailand and Cambodia have exchanged accusations over recent clashes at their shared border, resulting in fatalities and displacements. International pressure for a ceasefire is intensifying, with ASEAN urged to mediate.

The Cambodian government described the action as a serious violation of international law, including the United Nations Charter and the ASEAN Charter. They added that the Thai aggression "not only endangers peace and stability along our shared border but also demonstrates utter disregard for regional norms and international legal obligations."

Both nations accused each other of starting the military clashes and have downgraded their diplomatic relations since Wednesday. Thailand also sealed all land border crossings with Cambodia.

Thailand bombed Cambodia with F-16 fighter jets on Thursday, as relations between the two countries imploded following clashes on a disputed border near the Emerald Triangle.
