The US Treasury Department's Office of Foreign Assets Control (OFAC) has imposed sanctions on individuals and entities linked to the Sinaloa Cartel for laundering drug proceeds through cryptocurrency networks. The sanctions target networks that launder profits from fentanyl and other narcotics trafficking back to Mexico using blockchain technology. Key figures in the laundering operations include Jesus Gonzalez Penuelas and Armando de Jesus Ojeda Aviles, who lead the drug trafficking and money laundering schemes, respectively. The Sinaloa Cartel, led by the sons of Joaquin "El Chapo" Guzman Loera, has been designated a Foreign Terrorist Organization by the US. Despite the arrest of Rodrigo Alarcon Palomares, a key associate, the cartel's activities continue to thrive. The sanctions also target several other associates, including Jesus Alonso Aispuro Felix and Alfredo Orozco Romero, as part of efforts to protect American communities from the cartel's influence. Treasury Secretary Scott Bessent emphasized the administration's commitment to preventing narco-terrorists from exploiting US borders.
