Bangkok, Thailand – November 10, 2025 – Thailand has suspended the implementation of a United States-brokered peace agreement with neighboring Cambodia after a landmine explosion near their shared border injured two Thai soldiers. The incident has reignited tensions between the two Southeast Asian nations, which had previously signed a ceasefire following a series of deadly clashes.

Details of the Landmine Incident

The explosion occurred in Sisaket province, close to the Thai-Cambodia border, as soldiers conducted a routine patrol. Both injured soldiers were promptly treated on-site before being transferred to a hospital for further care.

Thai Prime Minister Anutin Charnvirakul confirmed that all planned actions under the peace agreement will be paused until Thailand’s demands—which have not been publicly specified—are met.

“The hostility towards our national security has not decreased as we thought it would,” Anutin stated, underscoring the continuing fragility of the truce.

At the time of reporting, Cambodia had not issued an immediate response to the suspension.

Background: Thai-Cambodian Border Conflict

Thailand and Cambodia have a history of territorial disputes, with recent clashes in July 2025 resulting in the deaths of at least 43 people and the displacement of over 300,000 civilians along the border.

The two countries signed a ceasefire during the ASEAN summit in Malaysia last month, mediated with support from the United States. The agreement included provisions for:

• The release of 18 Cambodian soldiers held by Thailand
• Mutual removal of heavy weapons and landmines from the border region

However, tensions have persisted, with both sides accusing each other of breaching the ceasefire. Thai authorities have claimed that Cambodia may have planted new mines, a charge the Cambodian government denies.

Impact on the Peace Process

Following the landmine blast, Thailand has postponed the release of the 18 Cambodian soldiers, originally scheduled for this week. The Thai army continues to investigate the explosion, with Defence Minister Natthaphon Narkphanit stating that the origin of the mine—whether newly planted or leftover—remains unclear.

Although some progress has been made on arms removal along the border, Thailand claims Cambodia has obstructed efforts to clear landmines. Conversely, Cambodia maintains its commitment to the truce and urges Thailand to release detained soldiers immediately.

International Mediation and Challenges

The truce, initially mediated by the United States and supported by ASEAN, came after former US President Donald Trump threatened tariffs as leverage. While Trump has claimed credit for several peace deals, analysts have noted that these agreements often focus on quick ceasefires rather than resolving underlying territorial and political disputes.

Experts warn that without a comprehensive resolution to the century-long border conflict, the Thai-Cambodian truce remains fragile and susceptible to renewed hostilities.

“A lasting peace requires addressing the root causes of the conflict, not just temporary pauses in fighting,” analysts noted.

Continuing Tensions

Since the July ceasefire, sporadic incidents—including landmine explosions—have occurred, highlighting ongoing security challenges in the border region. Both Thailand and Cambodia remain on alert, with the international community closely monitoring developments.

The recent suspension of the peace deal underscores the need for sustained diplomatic engagement and careful border security management to prevent further escalations between the two nations.
