Chinese Fentanyl Network Linked to Japanese Crypto Fraud Scheme

The operation centered on Hubei Amarvel Biotech, a Wuhan-based chemical firm whose executives were convicted of money laundering and importing illegal precursors. Investigators identified a Nagoya-based entity, Firsky, as a Japanese front for the organization. While Firsky was liquidated in July 2024, blockchain analysis links the network to more than 120 transactions involving entities already under U.S. sanctions. These financial trails lead back to the Wuhan Yuancheng Group, an organization associated with Chuen Fat Yip, a high-profile target of a $5 million State Department bounty.

To deceive victims, the scammers utilized the Zksync.jp domain, mimicking the legitimate ZKsync Ethereum Layer 2 network developed by Matter Labs. Although the domain requires a local Japanese address for registration, records suggest the registrant was a Hong Kong-based Chinese national with deep financial ties to Amarvel. This use of Japanese infrastructure highlights a growing challenge for Tokyo as it attempts to foster a regulated crypto environment. With nearly all Chinese precursor manufacturers now accepting digital assets for illicit chemical sales, the intersection of drug trafficking and sophisticated financial fraud continues to complicate international enforcement efforts.
