US Issues New Cambodia Travel Advisory Citing Crime, Unrest, UXO

The U.S. State Department has updated its travel guidance for Cambodia, urging Americans to exercise increased caution because of crime, unrest, and unexploded ordnance, while singling out specific higher-risk areas including the Thai border.

What the new U.S. advisory says and when it was issued

The updated advisory, dated September 15, 2026, lists Cambodia at Level 2, “Exercise Increased Caution,” citing three main drivers: crime, unrest, and unexploded ordnance.

Within that overall Level 2 assessment, the guidance highlights elevated risks by location. It advises against travel to areas along the Cambodia-Thailand border because of unrest, and it also calls for heightened caution in Phnom Penh because of crime.

The advisory additionally flags unexploded ordnance concerns in multiple provinces, including Battambang, Banteay Meanchey, Pursat, Siem Reap, Pailin, Kampong Thom, and Preah Vihear, an update that may affect itinerary planning for travelers heading beyond major city centers.

Crime and personal safety: Phnom Penh focus and robbery guidance

Published coverage tied to the updated advisory has emphasized street crime risks in Phnom Penh, especially in areas where travelers congregate, with phone and bag snatchings frequently cited as common scenarios.

A key point repeated in reporting around the advisory is practical: travelers confronted by theft are urged not to physically resist, since resistance can escalate the risk of injury. That warning is framed as general travel safety advice rather than a prediction of specific threats.

For visitors, the update is a reminder to tighten everyday precautions that are easy to overlook on a short trip: keep phones secured rather than in-hand at curbside, avoid displaying wallets or passports in crowded settings, and consider using crossbody bags that stay zipped and close to the body when moving through busy streets.

Border-area tension: the Thailand-Cambodia zone at higher risk

The advisory draws a bright line around the Cambodia-Thailand border region, where the U.S. warning elevates risk due to unrest and potential instability. That matters for travelers who might be considering overland routes, side trips near the frontier, or last-minute itinerary changes.

Other governments’ travel advisories issued or updated in mid-September 2026 have also highlighted the border zone as unpredictable and have advised avoiding travel within roughly 50 kilometers of the Thailand-Cambodia border. The convergence of guidance from multiple countries can be useful for travelers weighing whether a border crossing or a remote detour is worth the added uncertainty.

For travelers already in Cambodia, the practical takeaway is to check routing carefully, particularly for road travel in northwestern and northern provinces that can lie closer to the frontier than expected, and to keep plans flexible if the security environment changes quickly.

Unexploded ordnance: provinces cited and how it can affect sightseeing

The updated U.S. advisory explicitly identifies unexploded ordnance as a concern in several provinces that are common jumping-off points for cultural and outdoor tourism, including Siem Reap and Preah Vihear. While the highest-profile attractions are generally on established routes, the risk becomes more relevant when travelers venture into rural areas, forests, fields, or unmarked paths.

Public guidance associated with UXO risk commonly stresses simple rules: do not touch unknown metal objects, avoid leaving marked paths, and use reputable local guides when traveling in more remote areas. The danger is not only theoretical; explosive remnants of war can persist long after conflicts end, and risk can be uneven across short distances.

For trip planning, that can mean choosing well-trafficked routes for hiking or countryside excursions, asking tour operators how they select routes in rural areas, and treating unofficial shortcuts or off-road adventures as higher-risk activities, particularly in provinces named in the advisory.

Travel planning implications: insurance, support limits, and where to check updates

Published coverage of the updated advisory has also highlighted the importance of travel insurance for Cambodia, including confirming whether a policy covers medical care, emergency evacuation, and trip interruptions. For many travelers, those details matter most when plans involve remote provinces, long-distance road travel, or activities outside city centers.

Travelers should also factor in that advisories can change by area even when the country’s overall level stays the same. The State Department’s country-by-country advisories are designed to communicate both the national headline level and location-specific cautions, so it is worth re-checking guidance close to departure and again if plans shift while on the ground.

For Americans traveling soon, the most actionable approach is to treat the September 15, 2026 update as a prompt to map routes against the advisory’s higher-risk areas, set a conservative plan for nights out and transit in Phnom Penh, and keep day-to-day flexibility for border-region volatility and rural itinerary changes.
