Border Clashes in Thailand and Cambodia: Travel Safety Tips for Visiting Angkor Wat, Phuket, and Chiang Mai – Here’s What Every Traveler Needs to Know

Published on December 17, 2025

Thailand and Cambodia, two of Southeast Asia’s most visited countries, are currently grappling with heightened border tensions that have sparked concerns about travel safety. The longstanding territorial dispute between the two nations has led to military conflicts and border closures, raising alarm among potential tourists. While both countries continue to reassure the public that tourism is unaffected in major tourist destinations, the situation is fluid and could impact travelers, especially those near the borders.

As the border dispute between Thailand and Cambodia intensifies, travelers are advised to stay informed and cautious before planning any trips. Despite the conflict, the major tourist hotspots in Bangkok, Phuket, and Chiang Mai are reported to be largely unaffected. However, certain border areas, especially those in the eastern and northeastern provinces of Thailand, are experiencing increased security, with military presence and temporary restrictions in place. Martial law has been declared in specific zones like Chanthaburi, Sa Kaeo, and Trat, and train services have been suspended in some areas.

U.S. State Department Advisory for Thailand and Cambodia

The U.S. State Department has issued a Level 2 travel advisory for Thailand, recommending that travelers exercise increased caution due to ongoing civil unrest in southern regions. For the first time, the U.S. government has raised its warning for the border region between Thailand and Cambodia to Level 4: Do Not Travel, citing direct threats from military clashes and rocket fire along the border. Travelers are also urged to avoid areas within 50 kilometers of the Thai-Cambodian border to reduce the risk of exposure to conflict zones.

In Cambodia, the situation is similarly volatile. While the capital Phnom Penh and other popular destinations are not directly affected by the violence, the border zones are increasingly dangerous. The U.S. has confirmed limited support capabilities for American citizens in the region, further emphasizing the risks of travel to these disputed areas.

Impact on Popular Tourist Destinations

Despite the border tensions, tourists heading to Angkor Wat in Cambodia and other cultural landmarks like Siem Reap have not been directly impacted by the military conflict. However, a recent bombing by the Thai military, aimed at a civilian camp located about 70 kilometers from Angkor Wat, has prompted concerns. While this incident occurred outside the immediate area of Angkor Wat, the proximity to one of the world’s most visited UNESCO World Heritage sites has caused some travelers to reconsider their travel plans.

The dispute, which escalated after clashes between Thai and Cambodian forces on December 7, 2025, has led to civilian casualties and displacement of nearly 800,000 people, according to reports from France 24. As the conflict continues, several local businesses in border regions have been affected, leading to disruptions in regional tourism.

What Should Travelers Know?

For tourists planning to visit Thailand or Cambodia, it’s crucial to stay updated with travel advisories from both local and international authorities. The conflict is concentrated around the border area, so it is advisable to avoid travel to Sa Kaeo, Chanthaburi, and Trat in Thailand, and the neighboring border areas in Cambodia. Travelers should also check with their travel providers for updates on flight and bus service cancellations or changes.

Travel Tips for Thailand and Cambodia Amidst Border Conflict

• Avoid Border Zones: The Thai and Cambodian borders are experiencing significant instability. Avoid traveling within 50 kilometers of the conflict zones to ensure your safety.
• Stay Informed: Regularly check government websites or trusted news sources for updates regarding the conflict and any potential disruptions to local services.
• Reconsider Travel to Military Zones: While most popular tourist destinations remain unaffected, military zones near the border should be avoided, especially for those traveling by land or rail.
• Book Flexibly: Given the volatility of the situation, consider booking accommodations and transportation that offer flexible cancellation or rescheduling policies.
• Monitor Health and Safety: Increased security measures in certain areas may affect daily activities, so be prepared for potential delays and disruptions.

What’s Next for Thailand and Cambodia’s Tourism Industry?

While the conflict remains contained to certain areas, the impact on tourism could be far-reaching. Both Thailand and Cambodia rely heavily on tourism, with millions visiting each year to experience their rich culture, temples, and natural beauty. The uncertainty surrounding the border conflict may deter future travelers, especially those from countries with heightened travel advisories.

The governments of both nations have reassured international visitors that areas beyond the conflict zones, like Bangkok, Phuket, and Siem Reap, are operating as usual. However, the tourism industry will likely face economic challenges if the conflict intensifies or spreads.

Travel Alternatives for Adventurous Travelers

If you’re still keen on visiting Southeast Asia, consider focusing on destinations outside the affected regions. In Thailand, regions like Krabi, Ko Samui, and Hua Hin remain peaceful and popular with tourists. Similarly, in Cambodia, cities like Phnom Penh and Battambang offer rich cultural experiences and are far removed from the conflict zones.

A Final Thought for Travelers

Although the situation is concerning, the major tourist areas in Thailand and Cambodia remain safe for travelers. However, it is crucial to monitor the news closely and stay updated with any official travel advisories. If you have plans to visit either country, focus on areas away from the conflict zones and ensure your travel arrangements are flexible in case of unexpected changes.
