Thailand’s DSI Expands Probe Into Illegal Crypto Mining Linked to Chinese Criminal Network
Thailand has expanded its investigation into a large-scale cryptocurrency mining and money laundering operation allegedly linked to a transnational Chinese criminal network that processed more than $300 million annually through illegal financial activities.
The Department of Special Investigation (DSI) announced that authorities are intensifying efforts against the syndicate, which is accused of using illicit crypto-mining operations and complex financial structures to launder proceeds generated from online gambling, cyber fraud, and call center scams. Investigators believe the network operated across multiple countries and relied on cryptocurrency infrastructure to move and conceal funds.
The latest developments follow a series of coordinated raids conducted throughout 2025 by Thailand’s Technology and Cyber Crime Bureau. During the operations, authorities seized more than 6,390 cryptocurrency mining machines from several locations. Officials allege that the mining facilities were powered through illegally connected electricity lines, resulting in an estimated $29 million in stolen electricity from Thailand’s Provincial Electricity Authority (PEA).
Authorities described the case as one of the largest utility theft and illegal crypto-mining operations uncovered in the country. Investigators say the stolen power significantly reduced operating costs for the mining activities, enabling the syndicate to generate substantial profits while avoiding legitimate expenses.
Corrupt Officials, Myanmar Cash Couriers, and $307 Million in Annual Transactions
The investigation has also expanded to include public officials and private individuals suspected of assisting the operation. The DSI has forwarded two separate cases to Thailand’s National Anti-Corruption Commission involving seven electricity authority employees, one police officer, and 13 investors and associates believed to have facilitated or benefited from the network’s activities.
According to investigators, the organization laundered funds through various corporate entities and bank accounts that showed unusually high transaction volumes. To move money through the financial system, the group allegedly employed Myanmar nationals to conduct daily cash withdrawals from Thai banks ranging between $910,000 and $1.5 million. Authorities estimate that these transactions totaled at least $307 million per year.
U.S. Intelligence Links, Arrest Warrants, and Prosecutors Preparing for Trial
International cooperation has played a key role in the investigation. Thai officials revealed that intelligence shared by U.S. law enforcement agencies linked one of the alleged masterminds, Wang Yicheng, to a major digital asset fraud operation. The U.S. Secret Service previously seized more than $17.8 million in cryptocurrency connected to Wang as part of a broader fraud scheme that reportedly caused nearly $61 million in losses.
Thai authorities have already issued arrest warrants for eight suspects, including four Chinese financiers and four Myanmar nationals believed to be involved in the cash withdrawal network. Additional warrants are being sought, while several other individuals have been summoned for questioning and possible prosecution.
Officials emphasized that illegal cryptocurrency mining is no longer viewed as a simple case of electricity theft. Instead, they see it as a critical component of sophisticated international criminal operations that can facilitate cybercrime, financial fraud, and large-scale money laundering. Prosecutors are now preparing the case for trial as the investigation continues to expand.
