The U.S. Treasury Department’s Office of Foreign Assets Control on Wednesday imposed sanctions on four Mexican nationals and 13 companies allegedly operating a timeshare-fraud scheme on behalf of the Cartel de Jalisco Nueva Generación in and around Puerto Vallarta, Jalisco. The move freezes any U.S. assets held by the parties and bars American individuals and businesses from transacting with them. Treasury Secretary Scott Bessent said the action is part of a broader effort to disrupt alternative revenue streams used by the U.S.-designated foreign terrorist organization, adding that the cartel is “flooding our country with fentanyl.” Officials warned current and prospective U.S. owners of Mexico-based timeshares to exercise heightened due diligence, noting that schemes often target older Americans. According to Treasury and FBI data, approximately 6,000 U.S. victims reported nearly $300 million in losses to Mexico-based timeshare fraud between 2019 and 2023, while more than 250 Suspicious Activity Reports covering $23.1 million were filed in the six months after a 2024 FinCEN advisory on the scam. Separately, Mexico enacted reforms to its anti-money-laundering law the same day, extending mandatory audits to non-financial companies and requiring documents to be kept for up to 10 years, a measure aimed at tightening controls on illicit financing channels frequently exploited by criminal groups such as CJNG.
