Cambodia–Thailand Border Tensions Continue as ASEAN Confirms Landmine Incident: Updated December 2025

December 2025:

12th December: Donald Trump has posted on Truth Social regarding his telephone call between the two countries Cambodia and Thailand. Despite this however, it's being reported that hostilities are continuing and according to Al Jazeera neither side have confirmed independently the agreement to return to the ceasefire. There have now been confirmed reports of over 20 deaths and 270,000+people having to flee their homes.

Following the ceasefire agreement and the more formal agreement that followed, events on Monday have seen the worst escalation yet. Various media have reported that Thailand has launched airstrikes on the border area, however there is no official confirmation and it is unclear who fired the first shot, with both sides blaming each other.

The international community is calling for both sides to respect the ceasefire and honour the agreement as reported by Kiri Post.

Quick Recap of the Cambodia-Thailand Border Tensions

The dispute of the land border stretching 500 miles can be traced back to the 20th century.

It largely stems from a map created in 1907 whilst Cambodia was under French rule with Thailand holding firm that it is inaccurate. Additionally, many Thai people still disagree with the International Court of Justice ruling in 1962 that awarded sovereignty of the disputed land to Cambodia, being re-affirmed in 2013 and saw clashes between 2008 and 2011.

Thailand Suspends Cambodia Peace Accord Deal: What happened?

Cambodia and Thailand signed the Kuala Lumpur Peace Accord in late October 2025, a deal meant to de-escalate border tensions, remove heavy weapons, and launch joint land-mine clearance efforts.

However, today, some few weeks later, the Thai government announced a suspension of the agreement after a land-mine blast injured Thai soldiers near the border in Sisaket province. The halt means progress on reopening restricted areas and improving security cooperation is now on hold.

Are tourist areas affected? Is it safe to travel to Cambodia and Thailand?

As of 13/12/2025 the main tourist zones are unaffected. Bangkok, Chiang Mai, Siem Reap, Phnom Penh, and the islands remain safe, and open. Flights are running normally, and if you're inside either country you shouldn’t notice major changes. However flight prices to and from both countries are continuing to fluctuate due to higher demand and high season.

The particular issues are concentrated along border provinces (see below) such as Sisaket, Sa Kaeo, and Battambang, areas that most tourists don’t pass through unless doing overland crossings.

You can follow updates from your government foreign office website.

Thailand:

The US Embassy in Cambodia's maintains its security alerts and still recommends no travel within 50km of border areas.

It is important you stay informed of travel warnings if travelling to or near any of these areas as this could void your travel insurance policy.

What does this mean for travellers in Southeast Asia?

Exit from Thailand to Cambodia for border run is still not possible. You will have to fly to Siem Reap or Phnom Penh, or consider neighbouring countries. This could mean extra cost, so where possible avoid making plans in advance for travel to and from Cambodia.

Flights have risen recently due to the demand on flights between Cambodia and Thailand however they seem to now be stabilising again. Good deals can be found on bus routes to and from Laos/Vietnam but keep in mind visa costs.

It is important you stick to the mainstream tourist zones unless you are comfortable with the risk and have adequate insurance that covers border incidents. (Most policies don't)

Ensure you have appropriate travel insurance that covers you, and ensure you try to stay flexible with your accommodations and travel plans to avoid unnecessary spending.

When will the Cambodia-Thailand border re-open?

Up until today, things were looking positive. We will soon be publishing a deeper look into the border issue however, for now, quite simply despite the peace agreement and Trumps involvement; both sides don't trust each other. It is extremely uncertain when this, if at all will be resolved and thus the land border re-opening. Stay tuned for more detail on this.

Quick summary:

• The Cambodia-Thailand peace agreement deal has been suspended following a border mine blast
• Tourist areas remain safe and open
• Overland crossings are disrupted, currently not possible between both countries
• Stay updated if you're planning border run/have travel plans for either country
