The United States has officially leveled up its travel advisory on Thailand and Cambodia to Level 2 — Exercise Increased Caution for a mix of rising risks in the two Southeast Asia nations. The advisory, issued in response to heightened Thai-Cambodia border tensions as well as continuing unrest in Thailand’s southern provinces of Yala, Pattani and Narathiwat and safety hazards in Cambodia such as landmines in rural areas and rising street crimes particularly in major cities like Phnom Penh and Sihanoukville. The U.S. State Department has issued a lire warning to Americans of increasingly dire dangers from extremists in high-risk and less-developed areas near the common frontier of both two countries

This updated travel guidance, issued in late July, comes as geopolitical frictions between the two Southeast Asian neighbors remain unresolved and have triggered renewed concerns about the safety of American tourists. The U.S. government periodically assesses the global security landscape, using a four-tier system to advise its citizens on international travel. Level 1 indicates “normal precautions,” while Level 4, the most severe, advises “do not travel.” The current Level 2 designation for both Thailand and Cambodia means travelers are advised to stay vigilant, monitor developments, and remain aware of heightened risks.

Thailand: Localized Unrest and Regional Instability Raise Caution Levels

In its latest assessment of Thailand, the State Department highlights the persistent threat of violence in the country’s southern provinces, where conflict between security forces and armed insurgent groups has continued for years. The provinces of Yala, Pattani, and Narathiwat remain particularly volatile and have been operating under a state of emergency in multiple districts.

The warning outlines that periodic clashes and sporadic violent incidents have posed collateral risks, especially for travelers unfamiliar with the region’s long-standing security challenges. While tourist hubs such as Bangkok, Phuket, and Chiang Mai remain popular and generally safer, visitors are urged to avoid the southernmost areas entirely due to low-intensity conflict and unpredictable unrest.

Additionally, the State Department notes that political protests and mass gatherings—especially in urban centers—can escalate quickly and disrupt travel plans or compromise personal safety. Demonstrations, although often peaceful, have occasionally led to confrontations with law enforcement and public disturbances. As a result, U.S. travelers are advised to steer clear of rallies, monitor local news sources, and maintain situational awareness at all times.

Cambodia: Crime Risks and Landmine Dangers Spark Elevated Advisory

For Cambodia, the travel update focuses on a different set of risks. The State Department’s advisory stresses an increase in street crime, including frequent incidents of phone snatching and bag theft in areas popular with foreigners such as Phnom Penh, Siem Reap, and Sihanoukville. Tourists are especially vulnerable in crowded markets, nightlife zones, and transit hubs. Authorities warn that resistance during such crimes may lead to injury, underscoring the importance of caution and compliance.

In addition to petty crime, the advisory highlights that violent crimes such as sexual assault and even homicides have occurred, with some incidents involving foreign nationals. The advisory strongly encourages visitors to travel in groups, avoid poorly lit areas at night, and secure their belongings at all times.

Moreover, Cambodia continues to grapple with the deadly legacy of its wartime past. Undetonated landmines and unexploded ordnance remain present in several provinces, posing a serious risk to travelers venturing into rural or off-the-beaten-path locations. Provinces such as Battambang, Banteay Meanchey, Pursat, Pailin, Siem Reap, and Kampong Thom are specifically flagged as danger zones for these hidden hazards.

Travelers interested in exploring Cambodia’s countryside are urged to stick to well-trodden paths, avoid unmarked trails, and consult with local guides who are familiar with the region’s terrain and risk zones.

Border Area Warning: Avoid Travel Along Cambodia–Thailand Frontier

One of the most prominent components of the revised advisory is a firm warning to avoid travel near the Cambodia–Thailand border, where long-standing land disputes and military posturing have sparked intermittent tensions over the years. The U.S. State Department indicates that the area is susceptible to armed skirmishes and cross-border flare-ups, which could put travelers in harm’s way.

While no full-scale conflict has broken out in recent months, sporadic disputes and border incidents continue to fuel uncertainty and could escalate without warning. Visitors are advised to avoid any non-essential travel to remote or disputed frontier zones and remain informed through trusted news outlets and government updates.

Key Travel Recommendations for U.S. Citizens Visiting Thailand and Cambodia

In light of the updated advisory, American travelers are encouraged to take the following precautions:

• Sign Up for the Smart Traveler Enrollment Program (STEP): This complimentary service enables U.S. citizens to receive real-time safety alerts and ensures that U.S. embassies can reach them quickly during emergencies abroad.
• Remain Aware of Local Laws and Customs: Both countries enforce strict penalties for drug offenses and public misconduct. Knowing the cultural expectations and legal environment is essential for a smooth and respectful visit.
• Monitor Local News and Government Alerts: Events and political climates in Southeast Asia can shift quickly. Travelers should monitor local media, the U.S. Embassy websites in Bangkok and Phnom Penh, and global news platforms for timely updates.
• Use Reputable Transportation and Accommodations: Choose licensed taxi services and accommodations with good safety standards. Avoid traveling alone at night and refrain from accepting unsolicited travel offers.
• Exercise Extra Caution in Designated High-Risk Areas: Do not enter restricted zones, particularly in the southern provinces of Thailand and landmine-affected rural areas of Cambodia.

Southeast Asia Remains Popular, but Preparedness is Key

Thailand and Cambodia remain top destinations for millions of global travelers each year, celebrated for their vibrant cultures, scenic landscapes, and warm hospitality. However, the U.S. State Department’s Level 2 travel advisory underscores the importance of staying informed, vigilant, and well-prepared when exploring areas affected by regional tensions and evolving safety conditions.

While the majority of visits to both countries are completed without incident, travelers are reminded that awareness and preparation can significantly reduce personal risk and ensure a more secure and enjoyable journey.
