Thailand and Cambodia Sign Landmark Ceasefire to End Deadly Border War
By Lions Roar News Asia Desk
PHNOM PENH / BANGKOK (December 28, 2025) – In a major diplomatic breakthrough, Thailand and Cambodia have signed an immediate ceasefire agreement to halt weeks of the most intense border fighting seen in decades. The pact, signed yesterday at a border checkpoint by Thai Defence Minister Natthaphon Narkphanit and Cambodian Defence Minister Tea Seiha, went into effect at 12:00 PM local time on December 27, 2025.
The agreement aims to end 20 days of brutal combat that utilized fighter jets, heavy artillery, and rocket fire, resulting in at least 101 confirmed deaths and the displacement of over half a million civilians on both sides of the 500-mile frontier.
📜 Key Terms of the December Accord
Following three days of lower-level military talks and a special ASEAN summit in Kuala Lumpur, the two nations agreed to a comprehensive de-escalation plan:
- Freeze on Positions: Both militaries have committed to “maintain current troop deployments without further movement,” effectively freezing the frontline.
- Release of Prisoners: Thailand has agreed to repatriate 18 Cambodian soldiers held since previous clashes in July, provided the truce holds for an initial 72 hours.
- Civilian Return: Both governments will facilitate the safe return of thousands of displaced residents to their homes and schools.
- Demining Cooperation: In a rare show of unity, both sides will work through a Joint Coordinating Task Force on Humanitarian Demining to clear newly laid anti-personnel mines.
- Media Oversight: Both nations pledged to combat “fake news” and propaganda that fueled nationalist sentiments during the escalation.
🏔️ A Conflict Rooted in History
The 2025 conflict is the latest eruption of a century-old dispute over territories surrounding ancient Khmer temples, most notably the 11th-century Preah Vihear.
While the International Court of Justice (ICJ) ruled in favor of Cambodia in 1962 and 2013 regarding the temple itself, the surrounding 4.6 square kilometers of scrubland remain contested. The recent violence intensified in early December after a previous July ceasefire collapsed, with Thailand launching F-16 airstrikes and Cambodia responding with BM-21 rocket barrages.
🌎 International Pressure and Mediation
The path to this ceasefire was paved by significant international intervention. U.S. President Donald Trump reportedly spoke with both leaders earlier this month, threatening to withhold trade privileges unless a truce was reached.
Additionally, Malaysia, acting as the ASEAN mediator, played a central role in hostessing the General Border Committee (GBC) meetings that finalized the deal. ASEAN observer teams are now expected to be deployed to the border to monitor the implementation of the truce and ensure no unprovoked firing occurs.
