First Army launches operation to reclaim Thai border land in Sa Kaeo

MONDAY, DECEMBER 08, 2025

First Army Area has ordered military action in Sa Kaeo after detecting Cambodian troop and heavy weapons build-ups along the border.

  • The operation was launched in response to a significant Cambodian military buildup, including troops and heavy weapons, along the border in Sa Kaeo province.
  • Thailand's First Army viewed the Cambodian military movements as a threat to national sovereignty and the safety of civilians.
  • The First Army, through its Burapa Task Force, initiated the military action to reassert control over Thai sovereign territory.

The First Army Area Operations Centre received reports from the Burapa Task Force on Monday (December 8) of rising tensions along the Thai–Cambodian border.

Cambodian forces were assessed to be at the highest state of combat readiness along the frontier in Sa Kaeo province, with continuous movements of troops and military equipment, including heavy weapons, into fortified positions.

Cambodian units were also reported to be closely monitoring Thai positions, and throughout the morning, there were further reports of forces massing near the border.

The First Army Area concluded that these actions constituted a threat to Thailand’s sovereignty and to the safety of civilians living in the area, and were inconsistent with the Thai–Cambodian peace agreements.

In response, the First Army Area, through the Burapa Task Force, launched military operations to reassert Thai sovereign territory along the border in Sa Kaeo.

Further updates on the situation will be provided in due course.
