Thailand Suspends US-Backed Peace Deal with Cambodia After Landmine Blast Wounds Troops

A fragile US-backed peace deal between Thailand and Cambodia has been suspended by Bangkok, just a day after a landmine blast wounded four Thai troops, signaling a sharp return of tensions along the volatile border.

The deal, brokered by US President Donald Trump in October to wind down a conflict that killed at least 43 people in July, included commitments to withdraw heavy weapons and allow access for ceasefire monitors.

The decision to suspend implementation was confirmed by Royal Thai Army (RTA) chief Pana Klaewblaudtuk, who stated: “The truth has become clear that hostilities still remain.”

The RTA said the suspension was necessary “to safeguard our right to self-defence,” following the mine blast in Thailand’s Sisaket province. Thailand has frequently accused Cambodia of laying new landmines, a potential breach of the Ottawa Convention banning anti-personnel mines.

In response, Cambodia’s defence ministry expressed regret over the blast but insisted the munitions were “relics of past conflicts,” maintaining the situation on the front lines “remains calm” and that Cambodia is committed to the deal.

The suspension has immediate diplomatic consequences. Prime Minister Anutin Charnvirakul confirmed he will delay the release of 18 captured Cambodian troops, a key component of the peace plan.

Foreign Minister Sihasak Phuangketkeow announced the decision to suspend the deal would be reported to the United States and Malaysia, the co-chairs in the brokering process. Sihasak urged Cambodia to “take responsibility by showing regret, participating in the investigation and ensuring this does not happen again.” Analysts warn that while the truce has generally held since July 29, a comprehensive pact resolving the underlying territorial dispute remains elusive.
