Thailand–Cambodia ceasefire holds, barely: closed crossings, trades of blame, stalled talks

Summary

The Thailand Cambodia border holds a fragile, mistrustful calm. The 27 December 2025 ceasefire — brokered after a December flare-up resumed fighting that the July truce had paused — ended roughly 20 days of clashes that killed at least 101 people and displaced over half a million. Six months on, all crossings remain shut and both sides trade ceasefire-violation claims: Cambodia accused Thailand of breaches in January; Bangkok's military insists it is honouring the General Border Committee framework and the agreed Troop Deployment Line. The core deadlock is sequencing — Phnom Penh demands Thailand set a Joint Boundary Commission date and resume demarcation around Preah Vihear and Ta Muen Thom; the Thai Army conditions any JBC progress on de-escalation and verified landmine-clearing, and now also on a settled Thai government. The US pledged US$45m to support the truce in January.

By the numbers

• 27 Dec 2025 — date of the current ceasefire, after a December resumption of fighting.
• ~101 — killed in the late-2025 clashes; 500,000+ displaced on both sides.
• 12+ — border sites that saw fighting at the conflict's peak.
• All — Thailand–Cambodia crossings shut since the conflict; still closed as of June 2026.
• US$45m — US aid pledged (Jan 2026) to support the ceasefire.

Why it matters

A truce that leaves every crossing closed, the boundary undemarcated and both armies dug in is a pause, not a settlement. The dispute fuses deep nationalism on both sides with domestic politics — making it easy for either capital to reignite over a single incident — and a relapse would again displace hundreds of thousands and rattle Thailand's unstable politics.

What to watch

• Whether Thailand sets a JBC date and demarcation actually resumes — or stays hostage to mine-clearing.
• Any reopening of border crossings as a confidence signal.
• A fresh incident at Preah Vihear / Ta Muen Thom that breaks the December ceasefire.
