The U.S. Department of Justice announced Friday, April 14, sanctions against fentanyl trafficking networks that involve China and Mexico. Four sons of the Mexican cartel's founder, Joaquin "El Chapo" Guzman, are facing indictments. Two Chinese companies are also in the crosshairs of the US authorities: they are accused of supplying the cartel with chemical compounds necessary for the manufacture of fentanyl. Fentanyl is 50 times more potent than heroin and kills more Americans than terrorism, car accidents, cancer and Covid.
