U.S. President Donald Trump said he was planning to “make a phone call” on Wednesday (December 10, 2025) about the renewed clashes between Thailand and Cambodia over their contested border, which have prompted evacuations.

During a rally speech to supporters in the northeastern U.S. State of Pennsylvania on Tuesday (December 9, 2025), Mr. Trump listed various conflicts he has become involved with diplomatically, concluding with: “And I hate to say this, one named Cambodia-Thailand, that it started up today.”

“Tomorrow, I have to make a phone call, and I think they’ll get it,” Mr. Trump continued. “Who else could say, I’m going to make a phone call and stop a war of two very powerful countries’?”

Mr. Trump co-signed a truce between a Cambodia and Thailand in October during a visit to Asia.

The dispute between Thailand and Cambodia centers on a century-old disagreement over borders mapped during France’s colonial rule in the region, with both sides claiming a smattering of boundary temples.
