A Chinese national, Zheng Zhao, has been arraigned in the Central District of California after being extradited from the Netherlands to face federal charges tied to an alleged cryptocurrency-investment fraud scheme that prosecutors say targeted U.S. victims from scam compounds in Cambodia. According to the Justice Department, investigators identified at least 174 U.S. victims and traced more than $36.9 million through bank accounts and digital wallets connected to the operation.

The case is another high-profile example of the Justice Department’s increasingly cross-border approach to crypto-related fraud enforcement.
