Travelers Beware: These Popular Destinations Face An 'Unpredictable Security Situation'

No matter where you go in the world, there are general safety practices to remember, like avoiding dark alleys and keeping your personal items in secure bags. But some parts of the world are considered safer than others, and under the wrong circumstances, this perception can change rather quickly. This is why you should always research current events at your destination so you can stay safe. This is definitely the case for anyone heading to Thailand and Cambodia.

In December of 2025, the U.S. Embassy and Consulate in Thailand released a security alert stating, "U.S. citizens should avoid all travel within 50 kilometers of the Thailand-Cambodia border due to active hostilities and the unpredictable security situation. The U.S. government has limited ability to provide emergency services in affected provinces." Canada's government sent out a warning as well, advising citizens to "avoid all travel" to the border region. 

These alerts are in response to rising tensions and unpredictable political stability. While off-and-on issues concerning the border have existed for decades, the 2025 fighting broke out because both sides believe that the other violated a ceasefire back in July. The supposed violation was in the form of airstrikes which killed seven Cambodians and four Thais.

Thailand is an incredibly popular tourist destination — so much so that overtourism has become a concern in a few popular Thai hotspots. For example, "The White Lotus" brought larger crowds to the stunning island of Koh Samui. Other major tourist hotspots include the vibrant cities of Bangkok, Chiang Mai, and Phuket, along with the otherworldly Phi Phi Islands.

Cambodia welcomes tourists as well. The country's stunning Angkor Wat Buddhist temple is the largest religious structure in the world, attracting over 2 million visitors each year. It's a popular place for backpackers exploring Southeast Asia, with quiet islands, untouched jungles, and bustling cities like Phnom Penh. However, the swaths of tourists who hope to enjoy the amazing wildlife, nature, and cultures of these two countries might feel uneasy due to this new travel warning.

Thankfully, all of the aforementioned famous destinations in both Thailand and Cambodia are further than 50 kilometers (about 30 miles) from the border. Many foreign governments, like the U.S. and Canada, have long encouraged people to be cautious when visiting Thailand or Cambodia, even before the renewed border conflict. The main things to remember are to keep your valuables secure (in money belts or theft-proof bags), avoid any political demonstrations, and wear clothing that respects local customs. The latter is especially true when visiting religious landmarks. And for now, instead of crossing the border on a bus or train, opt to fly to avoid the conflict area.
