Travelers planning trips to Southeast Asia should take note: On July 25, 2025, the U.S. Department of State updated its travel advisories, elevating both Thailand and Cambodia to Level 2 (Exercise Increased Caution). The move comes in response to escalating tensions along the countries’ shared border, frequent local unrest, and heightened risks to tourists in specific regions.

Understanding the New Level 2 Travel Advisories

The U.S. Department of State issues travel advisories on a scale from Level 1 (Exercise Normal Precautions) to Level 4 (Do Not Travel). A Level 2 advisory urges Americans to “exercise increased caution,” highlighting a higher potential for danger but stopping short of warning against all travel.

This update is significant for American travelers, as Thailand and Cambodia are among the most popular destinations in Asia, attracting millions of visitors each year for their natural beauty, historical sites, and vibrant cities.

What’s Driving the Advisory Updates?

Cambodia: Crime, Unrest, and Unexploded Ordnance

The advisory for Cambodia specifically flags an “unrest” indicator for areas adjoining the Thai border due to periodic armed conflict between cross-border groups. The State Department notes that travel to these regions is not recommended:

• Remote border areas: Increased risks of armed clashes and historical landmines or unexploded ordnance, particularly in Battambang, Banteay Meanchey, Pursat, Siem Reap, Pailin, and Kampong Thom provinces.
• Phnom Penh and major cities: Officials warn visitors to remain vigilant against street crime, especially phone and bag snatchings, which have risen sharply in recent months.

Recent reports from the Cambodian government and international observers indicate a renewed focus on border security, but improved infrastructure and tourism growth have also brought an uptick in petty crime. Theft, pickpocketing, and scam-related incidents have increased by roughly 15% since the beginning of 2024, according to Cambodia’s Ministry of Tourism.

Thailand: Ongoing Insurgency and Border Tensions

The travel advisory for Thailand similarly cites unrest along the Cambodian-Thai border. But a longstanding security issue remains the primary concern: the insurgency in the far south. According to the U.S. Department of State, the provinces of Yala, Pattani, and Narathiwat — home to regular violent conflict between government forces and armed insurgents — continue to pose a “collateral risk of violence” for U.S. citizens and other travelers. These provinces remain under a declared state of emergency encompassing 17 districts.

• Periodic violence: In 2023 and 2024, over 200 incidents of bombings, shootings, and armed clashes were reported in the southern border provinces, leading to dozens of casualties.
• Travel risks: While major tourist hubs such as Bangkok, Chiang Mai, Phuket, and Koh Samui remain generally safe, officials urge travelers to avoid non-essential travel to the far south and remain up to date with local news, embassy bulletins, and government alerts.

The disruption has also affected cross-border trade and tourism. Both governments have increased military patrols and checkpoints, further complicating travel logistics in frontier regions.

Implications for U.S. Tourists and Cruise Travelers

Cruise tourism is a key driver for both countries, with Thailand’s ports such as Laem Chabang (Bangkok) and Phuket regularly welcoming major cruise lines. Cambodia’s Sihanoukville is also a rising port of call. According to Cruise Lines International Association (CLIA), Southeast Asia saw a 32% increase in cruise passengers from North America in 2023, with further growth expected for the 2024-2025 seasons.

However, increased caution is necessary for shore excursions, independent tours, and overnight stays. American citizens are encouraged to register their travel plans with the U.S. Embassy and review local guidelines. Insurance providers, including World Nomads and Allianz, have signaled updated policy terms for travel to high-risk border provinces.

Key Safety Recommendations

• Stay informed through the U.S. Department of State’s travel advisory portal
• Avoid travel to identified high-risk areas, including Cambodia’s remote borderlands and Thailand’s deep south
• Remain alert for crime in major cities; secure valuables and avoid displaying electronics or cash in public
• Consider comprehensive travel insurance covering medical emergencies and evacuation
• Keep contact information for the nearest U.S. consulate or embassy

Regional Impact: Tourism, Economy, and Government Response

Southeast Asia has experienced a tourism boom following the relaxation of COVID-19 travel restrictions. Thailand recorded over 27 million foreign tourist arrivals in 2023, while Cambodia surpassed 5 million — both rebounding to near pre-pandemic levels. For many communities, tourism represents a critical source of income and employment.

Government efforts to ensure tourist safety are ongoing. In Thailand, new security measures at airports and tourist zones have been rolled out, including the “Tourist Police” hotline and English-language safety campaigns. Cambodian authorities have intensified patrols around temples, resorts, and transport hubs, particularly in Siem Reap and Sihanoukville.

Despite the advisories, most tourist visits proceed without major incident. The U.S. remains among the top ten origin countries for both Thailand and Cambodia, and travel operators such as Disney Cruise Line, Viking, and Royal Caribbean continue offering itineraries with stops in these destinations. Still, experts caution that heightened vigilance from travelers is now more important than ever.

Practical Tips for Future Travelers

As circumstances evolve, travelers should:

• Monitor the latest advisories and news updates for your destination
• Choose reputable, licensed local guides for excursions
• Download embassy alert apps or subscribe to email alerts
• Share your travel plans with family or friends
• Maintain situational awareness and be prepared for quick itinerary changes

Both countries continue to offer exceptional cultural experiences, historic attractions, and friendly hospitality. By planning thoughtfully and prioritizing safety, travelers can continue to explore Southeast Asia’s treasures with confidence.
