The U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) issued this advisory to urge financial institutions to identify and report suspicious transactions involving Chinese money laundering networks (CMLNs) acting on behalf of Mexico-based transnational criminal organizations. The document details how CMLNs utilize mirror transactions, money mules, and trade-based money laundering to convert cartel drug proceeds into U.S. dollars for Chinese citizens seeking to evade currency controls. FinCEN requires institutions to reference this advisory in Suspicious Activity Reports by including the key term CMLN-2025-A003 and selecting relevant typology fields.
