The UK FCDO updated its Cambodia travel advice, advising against all but essential travel within 20km of the Thai land border due to conflict. Heavy fighting occurred in 2025, including airstrikes and artillery. A ceasefire was signed on 27 December, but tensions remain. Land borders and crossings are suspended, some border temples are closed, and unexploded ordnance poses risks.
The U.S. Department of State issued a Level 2 travel advisory for Cambodia, recommending increased caution. Reasons include crime, unrest, and unexploded ordnance. Some areas carry increased risk. Areas along the Cambodian-Thai border are marked Do Not Travel due to unrest. Phnom Penh requires increased caution due to crime. Battambang, Banteay Meanchey, Pursat, Siem Reap, Pailin, Kampong Thom, and Preah Vihear provinces require increased caution due to unexploded ordnance.
The U.S. Department of State raised Cambodia's travel advisory to Level 2 (Exercise Increased Caution), adding an 'unrest' risk indicator and an area of increased risk. The advisory cites crime and landmines, with frequent street crime in Phnom Penh and occasional violent crime. Areas within 50km of the Cambodia-Thailand border are Level 4 (Do Not Travel) due to armed conflict, with reports of rocket and artillery fire and civilian casualties.
