Cambodia has extradited businessman Chen Zhi, who is accused of operating one of the world’s largest cyber fraud networks, to China. The case highlights increasing international pressure against organised cybercrime groups operating across borders. It has attracted global attention due to allegations that the network targeted victims in multiple countries, including the United States.

Chen Zhi, also known as Vincent Chen, was the former chairman of Cambodia-based Prince Group. The business conglomerate has interests in sectors including casinos, real estate, and financial services. While the group has publicly presented itself as a legitimate enterprise, U.S. and international investigators have alleged that certain operations were used to facilitate large-scale online fraud and money laundering activities.

According to U.S. prosecutors, Chen Zhi was linked to hundreds of scam centres across Southeast Asia that specialised in online investment fraud, romance scams, and so-called “pig butchering” cryptocurrency schemes. In these operations, victims were gradually manipulated through online relationships and persuaded to invest in fake cryptocurrency platforms or fraudulent trading services. Authorities stated that hundreds of victims, including at least 250 U.S. citizens, suffered financial losses, with some individuals losing hundreds of thousands of dollars.

Cambodia proceeded with the extradition after reportedly revoking Chen Zhi’s Cambodian citizenship in late 2025. Although U.S. prosecutors had also filed charges related to wire fraud and money laundering, Chen Zhi was transferred to Chinese authorities on January 6, 2026. Legal analysts noted that China’s rapid action was influenced by Chen’s nationality and the significant financial impact involving Chinese victims.

Before the extradition, U.S. authorities imposed sanctions on Chen Zhi and affiliated entities and froze related assets. Investigators believe the alleged fraud network moved billions of dollars through cryptocurrency transactions and shell companies, demonstrating how digital assets can be exploited to conceal and transfer illicit funds.

Although Chen Zhi was not extradited to the United States, the case remains significant for American victims and the global fight against cyber fraud. It demonstrates growing international cooperation against organised scam operations and sends a strong message that large-scale fraud networks are facing increased scrutiny. Asset tracing and parallel investigations continue to play an important role in identifying funds and supporting potential recovery efforts.
