Thailand rejects Trump's offer to mediate peace deal with Cambodia

"The US President can only be helpful now if he can convince Cambodia to meet Thailand’s demands", Anutin said.

Charnvirakul made the remarks in response to questions about Trump's interest in presiding over the signing ceremony for the peace agreement later this month.

The agency noted that Trump's intervention earlier in 2025 helped end a brief but intense border conflict between Thailand and Cambodia.

He had threatened to block US trade deals with both countries if they did not stop the five-day fighting.

Trump's plans to preside over the signing of the peace agreement were previously reported by Politico, citing sources. The White House declined to comment.

"I only care about Thailand's interests, the safety of Thai people, and the nation's sovereignty. Anyone winning prizes has nothing to do with what Thailand has to do," Charnvirakul emphasized.

Thailand–Cambodia conflict

The armed conflict between Cambodia and Thailand erupted on July 24 following a border shooting incident that left soldiers dead on both sides.

Thailand deployed units to the border area equipped with Ukrainian Oplot infantry fighting vehicles and BTR-3E armored personnel carriers.

Thai aviation carried out strikes on military targets near Phnom Penh, while in the Trat province area, the army successfully repelled an attempted breakthrough by Cambodian forces.

On July 26, US President Donald Trump held a phone call with the leaders of Cambodia and Thailand. He reported that both sides expressed readiness to agree on a ceasefire.

In early August, Thailand and Cambodia reached an agreement to ease tensions along the border following negotiations in Kuala Lumpur, Malaysia. The countries signed a 13-point agreement.
