As clashes between Thailand and Cambodia escalated, the government raised the travel advisory level for border areas between the two countries, where a travel advisory level 2 (exercise caution) had been issued on the 25th.
On the 27th, the Ministry of Foreign Affairs announced that it had upgraded the travel advisory for five areas bordering Thailand and Cambodia to a special travel warning based on that day's information. A special travel warning is a level higher than travel advisory level 2 (exercise caution) but lower than level 3 (recommended to leave).
On that day, the areas in Cambodia that received a special travel warning included the existing Oddar Meanchey Province and Preah Vihear Province, along with Bantay Meanchey Province, Pailin Province, Battambang Province, Pursat Province, and Koh Kong Province, bringing the total to seven areas. All other regions were issued a level 1 (exercise caution) advisory.
In Thailand, three regions along the Cambodian border—the Sa Kaeo Province, Chanthaburi Province, and Trat Province—were upgraded to a special travel warning effective at 5 p.m. that day.
The Ministry of Foreign Affairs urged, "We advise our citizens who are planning to visit areas where a special travel warning has been issued to cancel or postpone their travels, and we ask those currently staying in those areas to move to safer regions."
Thailand and Cambodia, which share a border, have been engaged in armed conflict since the 24th. Although the two countries expressed their willingness to discuss a ceasefire mediated by U.S. President Donald Trump, clashes are still ongoing.
