Mae Sai Customs Seize More Than 23 Million Baht Hidden in Snack Boxes in Myanmar-Registered Car — Fears of Cross-Border Smuggling Rise

On June 27, 2026, officials at the Mae Sai customs checkpoint in Mae Sai District, Chiang Rai Province, inspected a Myanmar-registered vehicle passing through the border crossing and discovered more than 23 million baht in Thai banknotes concealed inside two boxes of snacks. The incident has raised alarm and questions about cross-border cash smuggling that could be linked to various illegal activities, including money laundering and drug trafficking networks.

Mae Sai customs officers said the search occurred during routine checks of a Myanmar-registered private car preparing to leave the country. Officers asked to inspect the luggage for contraband or prohibited items and found tightly packed snack boxes. When opened, the boxes contained stacks of 1,000- and 500-baht banknotes bundled together, totaling about 23 million baht. The authorities seized the cash and took the person in possession of it for further questioning.

The case aligns with efforts by law enforcement agencies in the northern border area to tighten scrutiny of cross-border cash movements, following reports of high-value asset transfers that may be connected to money laundering and transnational crime networks. Mae Sai is a key crossing point between Thailand and Myanmar, with significant trade and labor movement across the border. Smuggling cash inside food or consumer goods boxes is a method favored by smugglers because it draws little attention.

A security source in Chiang Rai Province said that after seizing the cash, relevant agencies will expand the investigation to trace the origin and destination of the money. Details about all parties involved cannot yet be released while evidence is being collected. Agencies involved in anti-money laundering may be invited to examine related financial trails. At the same time, customs officials are coordinating with Myanmar security counterparts to verify information about the vehicle and the registered owner.

The incident affects Chiang Rai residents and tourists in terms of confidence and convenience. Mae Sai is an economic gateway for trade and tourism; if cash smuggling or businessmen linked to illicit activities increase, authorities may ramp up inspections, affecting the convenience of travelers and cross-border traders. Nevertheless, many locals in Chiang Rai support stricter enforcement to reduce transnational crime and money laundering that could damage the border area’s reputation.

For tourists, Mae Sai is popular for shopping and visiting Myanmar. News of the seizure may encourage travelers to cooperate more, such as preparing complete documents and accepting searches for everyone’s safety. Cross-border freight operators may face more frequent inspections, temporarily affecting transit times. Local authorities urged residents and businesses to report any suspicious activity to help sustainably address the problem and preserve the stability of trade and tourism in the Chiang Rai border area.
