Donald Trump has said Thai and Cambodian leaders agreed to renew a truce after days of deadly clashes that threatened to undo a ceasefire the US administration helped broker earlier this year.

Trump announced the agreement to restart the ceasefire in a social media posting after calls with Thai prime minister, Anutin Charnvirakul, and Cambodian prime minister, Hun Manet.

“They have agreed to CEASE all shooting effective this evening, and go back to the original Peace Accord made with me, and them, with the help of the Great Prime Minister of Malaysia, Anwar Ibrahim,” Trump said in his Truth Social posting.

The original ceasefire in July was brokered by Malaysia and pushed through after pressure from Trump, who threatened to withhold trade privileges unless Thailand and Cambodia agreed. It was formalised in more detail in October at a regional meeting in Malaysia that Trump attended.

Despite the deal, the two countries carried on a bitter propaganda war and minor cross-border violence continued.

The roots of the Thai-Cambodian border conflict lie in a history of enmity over competing territorial claims. These claims largely stem from a 1907 map created while Cambodia was under French colonial rule, which Thailand maintains is inaccurate. Tensions were exacerbated by a 1962 international court of justice ruling that awarded sovereignty to Cambodia, which still riles many Thais.

Thailand has deployed jet fighters to carry out airstrikes on what it says are military targets. Cambodia has deployed BM-21 rocket launchers with a range of 30-40km (19-25 miles).

According to data collected by public broadcaster ThaiPBS, at least six of the Thai soldiers who were killed were hit by rocket shrapnel.

The Thai army’s northeastern regional command said on Thursday that some residential areas and homes near the border were damaged by BM-21 rocket launchers from Cambodian forces.

The Thai army also said it destroyed a tall crane atop a hill held by Cambodia where the centuries-old Preah Vihear temple is located, because it allegedly held electronic and optical devices used for military command and control purposes.
