BANGKOK, THAILAND – Thailand raised security checks on foreign visitors to maximum levels amid escalating border clashes with Cambodia.
Authorities on high alert over alleged foreign spies
Against the backdrop of intensified skirmishes with Cambodia, Thai authorities were on their highest state of alert for alleged foreign spies and saboteurs. The Immigration Bureau massively tightened inspections and ordered that every arriving foreigner be checked in full.
Police deny viral claims of mercenaries on Ko Pha-ngan
Initial relief came when officials rejected a viral horror story about alleged armed mercenaries on Ko Pha-ngan. The joint press centre at the border dismissed reports that the island had been infiltrated by gunmen as false.
“The provincial police of Surat Thani and security agencies have checked the information and confirmed that it is false.”
said Police Colonel Siriwat Deepor, deputy police spokesperson.
Investigations were launched against those who spread the fake news for alleged violations of the Computer Crimes Act, which provided for up to five years in prison and a fine of 100,000 baht (about 2,500 euros).
Immigration deploys full staff for 100% screening
The main development was a dramatic tightening of security measures at entry points. The Immigration Bureau deployed 100% of its personnel to screen foreign nationals arriving in the country.
Officials said the aim was to reassure the public and prevent people with malicious intentions from entering as spies or conducting espionage and unrest. Borders were being sealed off as tightly as possible.
Deleted police post warned of Russian nationals
Confusion and concern grew after an official but swiftly deleted police post from Nakhon Ratchasima, also known as Korat. In that message, the Phon Krung police station had warned about Russian citizens who were said to have been hired by Cambodia.
They were reportedly tasked with scouting and attacking military facilities such as the Korat Royal Thai Air Force Base, in some cases using drones. The unexplained removal of the post fuelled intense speculation on social media.
Public told how to spot potential spies
Police later circulated general guidance on how citizens could identify suspected spies. They said people should be wary of those secretly filming or recording military facilities or troop movements, or closely tracking military activities.
Other red flags included unusual behaviour near military sites or measuring areas without any clear reason, entering restricted zones, and carrying suspicious equipment such as binoculars, maps, GPS devices or drones. Police warned of the severe penalties under Thai law, which in extreme cases could include the death penalty.
Tourism officials seek to calm visitors
Despite the tense security climate, the tourism authority tried to reassure travellers. A spokesperson said Thailand was in its high season over Christmas and New Year and that international arrivals had passed the 30‑million mark.
According to the authority, border skirmishes had only limited impact on tourism flows. At the frontier, however, the situation remained deadly, with a 16th Thai soldier reported killed on 14 December.
Public urged to limit war imagery online
Residents were called on not to post images of combat operations, in order not to compromise ongoing missions. Officials stressed that the fear of an “invisible enemy” within the country was real and that online rumours could deepen public anxiety.
Security versus openness under scrutiny
Authorities found themselves under pressure as rumours travelled faster than confirmed facts. The escalation raised questions about where necessary caution ended and fear-driven policy began in Thailand’s response.
The tightened checks were presented as a signal of protection and control, but they also posed risks for openness and trust during the peak tourist season. The debate underscored that, in times of heightened tension, transparency was seen by many as almost as important as security itself.
