The U.S. Department of State has recently updated travel advisories for Thailand and Cambodia, elevating both countries to Level 2 – Exercise Increased Caution – as of July 25, 2025. These advisories reflect rising concerns over border region security and ongoing local safety risks for American tourists and expatriates.

Background: What Prompted the Change?

The heightened travel warnings come amid periods of armed conflict and tension along the border between Cambodia and Thailand. The disputed territory and sporadic military exchanges in recent years have underscored longstanding complexities in diplomatic relations. While full-scale conflict remains unlikely, travelers are urged to remain vigilant as even localized violence and civil unrest can affect foreign nationals.

“Periodic violence between Thai security services and armed insurgents has been known to occur in Thailand’s three southernmost provinces of Yala, Pattani, and Narathiwat. Seventeen districts remain under a declared state of emergency due to ongoing conflict.”

Key Security Concerns: Cambodia

• Street Crime in Phnom Penh: Incidents of theft, purse snatching, and pickpocketing are frequently reported in the capital, particularly in crowded markets and tourist-heavy districts. The U.S. Embassy highlights vigilance with personal belongings, especially electronics and travel documents.
• Landmines and Unexploded Ordnance (UXO): Provinces such as Battambang, Banteay Meanchey, Pursat, Siem Reap, Pailin, and Kampong Thom still contain significant minefields and unexploded ordnance from previous decades of conflict. Travelers venturing off established paths or into remote areas should be especially cautious.
• Border Security: The border region with Thailand is a particular hotspot for tension, and sporadic reports of armed clashes or increased military presence remain. Crossing borders by land can sometimes be subject to additional scrutiny or sudden closures.

Despite these concerns, Cambodia continues to welcome millions of foreign visitors annually. The world-renowned Angkor Wat temple complex, the capital Phnom Penh, and other cultural sites remain open, but travelers are encouraged to arrange reputable local guides and use trusted transportation services.

Key Security Concerns: Thailand

• Southern Provinces: The southern border provinces of Yala, Pattani, and Narathiwat continue to experience low-intensity insurgency-driven violence. Bombings, shootings, and improvised explosive device (IED) attacks occur sporadically, primarily affecting local security forces, but occasionally resulting in civilian casualties or collateral damage. The U.S. government restricts personnel from official travel to these areas without special authorization.
• General Safety: Thailand’s urban centers, including Bangkok, Chiang Mai, and Phuket, remain safe for travelers with standard precautions. However, petty crimes such as bag-snatching and scams targeting tourists are noted, especially during festivals or in crowded transit hubs.
• Political Climate: Recent years have witnessed periodic rallies and demonstrations in Bangkok and other major cities, often spurred by national politics or economic discontent. While protests are typically peaceful, authorities advise avoiding large gatherings that can unpredictably escalate.

Thailand remains among the top global destinations for American and European travelers, reporting over 27 million visitor arrivals in 2023, with tourism expected to fully rebound by the close of 2025.

What Does Level 2 Advisory Mean for U.S. Travelers?

A Level 2 travel advisory does not prohibit or discourage travel; it signals that visitors should exercise increased caution due to risks not present in Level 1 countries. Travelers are encouraged to:

• Keep abreast of embassy updates and advisories via the U.S. State Department website and sign up for the Smart Traveler Enrollment Program (STEP).
• Use registered, reputable tourist services and avoid unauthorized taxis or informal guides.
• Carry minimal valuables, maintain vigilant situational awareness, and know local emergency contact protocols.
• If visiting border areas or remote regions, travel with guided tours and adhere strictly to marked paths to avoid minefields and UXOs (particularly in Cambodia).
• Be mindful of evolving conditions; outbreaks of violence or protest can occur with little warning, especially in border or high-tension areas.

The U.S. Embassy in Phnom Penh and the Embassy in Bangkok both provide regular updates for travelers. It is emphasized that while increased caution is important, responsible tourism and proper planning enable safe, enjoyable visits across most of Thailand and Cambodia.

Advice for Business and Leisure Travelers

Whether traveling for work, leisure, or long-term stay, visitors to Southeast Asia should review their travel insurance options, including coverage for medical evacuation and trip interruption. Ensure copies of passports and other essential documents are stored securely online and offline.

With ongoing infrastructure improvements and resumed international flight routes in 2025, Thailand and Cambodia continue to recover robustly from the COVID-19 pandemic’s impact on their tourism economies. The World Tourism Organization notes both countries are expected to achieve pre-pandemic visitor numbers by late 2025, driven by pent-up demand and regional events such as the 2025 Southeast Asian Games.

Preparing for International Travel: Final Tips

• Check visa requirements and validity for both entry and exit.
• Be up to date on recommended vaccinations, including for COVID-19, hepatitis, and typhoid.
• Stay connected with local news, embassy security alerts, and your own travel provider for potential itinerary changes.

As with all international destinations, staying informed and aware remains the best safeguard. For further guidance, consult the latest U.S. government advisories, and utilize official travel resources to make your trip both safe and memorable.
