The United States Treasury Department has imposed sanctions on Cambodian senator Kok An, accusing him of using his political influence to shield a network of online scam operations targeting American citizens. The Treasury's Office of Foreign Assets Control (OFAC) announced measures against An and 28 associated individuals and entities, alleging they ran fraud centres out of casinos and repurposed office parks, using fake romantic or investment schemes to trick victims into handing over digital assets. The action is part of a broader US crackdown on Southeast Asia's sprawling scam industry, which the United Nations estimates may involve up to 300,000 people across the region, some held and forced to work against their will.
