Thailand announced on Monday that it had suspended the implementation of a peace agreement with Cambodia, which was mediated by US President Donald Trump. The decision came after a landmine explosion wounded two Thai soldiers in a contested border region, AFP reported.

The peace accord, signed last month in Malaysia, had been hailed by Trump as a diplomatic success. However, tensions between Thailand and Cambodia have persisted, casting doubt on the deal’s future.

Border Tensions Resurface

In July, the two Southeast Asian neighbours fought a short but intense border war that left at least 43 people dead and displaced over 300,000 on both sides. The conflict involved heavy artillery, rockets, airstrikes, and ground fighting, following months of rising hostility.

Although the US-brokered peace deal temporarily halted the violence, the latest blast has raised new concerns about security and trust.

Thailand Says Threat Still Exists

Prime Minister Anutin Charnvirakul said Thailand had hoped the peace deal would reduce the threat but admitted that tensions remain high.
“We thought that the security threat had eased, but it has not actually decreased,” Anutin said, according to AFP.

The Royal Thai Army confirmed that the explosion took place in Sisaket province. One soldier suffered a serious leg injury, while another sustained minor wounds.

Following the incident, the Thai government announced it would suspend “the follow-up to the joint declaration,” halting the next phase of the peace process. That phase would have included the release of 18 detained Cambodian soldiers.

Cambodia Reaffirms Commitment to Peace

While Cambodia did not directly comment on the landmine attack, its government released a statement reaffirming its dedication to peace and regional stability. It said it maintained an “unwavering commitment” to uphold the peace agreement.

Longstanding Border Dispute

Tensions between Thailand and Cambodia date back decades. The two countries have long disputed parts of their shared border, particularly the area known as the “Emerald Triangle,” where the borders of Thailand, Cambodia, and Laos meet.

This region holds deep cultural and strategic importance. Both sides claim ownership of key heritage sites, including the ancient Prasat Ta Muen Thom temple.

Earlier this year, before the larger conflict erupted, Thai and Cambodian forces had already clashed near the temple, signaling that the peace in the region was fragile.
