The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) announced sanctions against Cambodian Senator Kok An, accusing him of controlling a nationwide network of “fraud parks” that defrauded U.S. victims through cryptocurrency investment scams. According to a statement released by OFAC on Thursday, in addition to Kok An, 28 other individuals and entities were added to the sanctions list, all believed to be linked to his fraud network. This network is accused of using “high-return investments” as bait to induce victims to send cryptocurrency assets. This action follows Cambodian police raids on two fraud centers in the border city of Poipet. Kok An had previously been accused of operating fraud bases in the area. OFAC stated that fraudsters typically gain victims’ trust by establishing “friendships” or “romantic relationships” before guiding them to participate in so-called cryptocurrency investment platforms, thereby defrauding them of millions of dollars. Notably, some of those involved in the fraud are themselves victims of human trafficking, forced to commit illegal acts under threats of violence. OFAC pointed out that these fraud centers are often located in casinos or converted office parks, serving not only as money laundering hubs but also as bases for defrauding U.S. citizens and violating human rights. In addition, regulators also simultaneously shut down more than 500 fake website domains used to carry out cryptocurrency investment scams, demonstrating that the United States is further intensifying its crackdown on related criminal activities.
