Thailand and Cambodia on Sunday signaled their readiness to negotiate an end to a deadly border dispute following mediation efforts by U.S. President Donald Trump. The fighting, now in its fourth day, has killed at least 34 people and displaced more than 168,000.
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. He later said both sides agreed to meet to negotiate a ceasefire.
Both sides agree to discuss a ceasefire
Cambodian Prime Minister Hun Manet said Sunday his country agreed to pursue an “immediate and unconditional ceasefire.” He said Trump told him that Thailand had also agreed to halt attacks following Trump’s conversation with Acting Thai Prime Minister Phumtham Wechayachai.
“This is positive news for the soldiers and people of both countries,” Hun Manet said in a statement.
He said he tasked his deputy, Foreign Minister Prak Sokhonn, to coordinate next steps with U.S. Secretary of State Marco Rubio and to engage directly with Thailand’s foreign minister to implement the ceasefire.
Thailand expressed cautious support. Phumtham thanked Trump and said that Thailand agreed in principle to a ceasefire but stressed the need for “sincere intention” from Cambodia, the Thai Foreign Ministry said. Phumtam called for swift bilateral talks to discuss concrete steps toward a peaceful resolution, it said.
The fighting first flared Thursday after a land mine explosion along the border wounded five Thai soldiers. Both sides blamed each other for starting the clashes. Both countries recalled their ambassadors and Thailand closed its border crossings with Cambodia.
Despite the diplomatic efforts, fighting continued Sunday along parts of the contested border, with both sides refusing to budge and trading blame over renewed shelling and troop movements.
Col. Richa Suksowanont, a Thai army deputy spokesperson, said Cambodian forces fired heavy artillery into Surin province, including at civilian homes early Sunday. He said Cambodia also launched rocket attacks targeting the ancient Ta Muen Thom temple claimed by both countries, and other areas in a bid to reclaim territory secured by Thai troops. Thai forces responded with long-range artillery to strike Cambodian artillery and rocket launchers.
Richa said Trump’s efforts to mediate was a “separate matter.” The battlefield operations will continue and a ceasefire can only happen if Cambodia formally initiates negotiations, he added.
“Any cessation of hostilities cannot be reached while Cambodia is severely lacking in good faith and repeatedly violating the basic principles of human rights and humanitarian law,” Thailand’s Foreign Ministry said separately.
Cambodian Defense Ministry spokesperson Lt. Gen. Maly Socheata accused Thai forces of escalating the violence with bombardment of Cambodian territory early Sunday, followed by a “large-scale incursion” involving tanks and ground troops in multiple areas.
“Such actions undermine all efforts toward peaceful resolution and expose Thailand’s clear intent to escalate rather than de-escalate the conflict,” she said.
Thailand on Sunday reported a new death of a soldier, bringing the total number of fatalities to 21, mostly civilians. Cambodia said 13 people have been killed. More than 131,000 people in Thailand have evacuated to safe locations and over 37,000 people fled from three Cambodian provinces. Many border villages are mostly deserted, with many schools and hospitals shut.
