Thailand Intensifies Crypto Mining Crackdown, Targeting Chinese Crime Syndicates
Thailand’s premier investigative agency is escalating its crackdown on illicit cryptocurrency mining operations, which it alleges are being used as a front for money laundering by Chinese-linked criminal syndicates.
The Department of Special Investigation (DSI) announced Friday that it has broadened its inquiry into a network of “grey” Chinese capital—a term referring to illicit funds channeled through seemingly legitimate avenues—connected to illegal mining and transnational money laundering. According to a DSI press release, these financial flows are estimated to exceed 10 billion baht ($300 million) annually.
The investigation originated from raids conducted in 2025, during which the DSI’s Technology and Cyber Crime Bureau dismantled three mining networks suspected of stealing electricity to power their equipment. Authorities confiscated over 6,390 machines, estimating the financial damage to the state-run Provincial Electricity Authority at more than 953 million baht, approximately $29 million. This incident represents one of the most significant instances of utility theft in recent memory.
Investigators claim these mining operations served as a central hub for laundering proceeds from call-center scams and online gambling. Myanmar nationals were reportedly recruited to withdraw substantial sums, ranging from 30 million to 50 million baht ($920,000 to $1.5 million) daily, in cash from Thai banks.
The DSI has issued arrest warrants for eight individuals, including four Chinese financiers and four Myanmar nationals. The agency is actively seeking seven additional suspects and has summoned five others to face charges.
One key figure identified by the DSI is Wang Yicheng, who is also a suspect in a major digital asset fraud case flagged by U.S. law enforcement. The U.S. Secret Service has seized over $17.8 million (approximately 620 million baht) in cryptocurrency linked to Wang, connected to losses exceeding 2 billion baht. Wang, a businessman based in Bangkok, had previously come under American scrutiny when the Secret Service traced funds from a U.S. scam victim to a cryptocurrency account in his name, which authorities linked to a “pig butchering” operation.
The probe has also implicated Thai officials. The DSI has referred two cases to the National Anti-Corruption Commission. These cases involve seven officials from the electricity authority, one law enforcement officer, and 13 investors or alleged accomplices accused of facilitating the miners’ access to power and aiding them in evading detection.
This expanded crackdown builds upon a series of raids that commenced in December, when the DSI seized 3,642 mining rigs valued at $8.6 million from locations associated with Chinese scam networks operating out of Myanmar.
The intensified efforts in Thailand align with a broader regional push across Southeast Asia to combat cryptocurrency-linked power theft. Malaysia’s state utility has reported approximately $1.1 billion in stolen electricity over the past five years, and the United Nations Office on Drugs and Crime has issued warnings that transnational gangs are increasingly utilizing illegal crypto mining for money laundering purposes, moving billions of dollars.
