China's Role in Fentanyl Trade

China plays a central role in the fentanyl trade, providing precursors used in production, pill presses, and secure communication devices to the Mexican drug cartels. The Chinese company controlling the Port of Monzanillo in Mexico handles the majority of these precursors. Additionally, Chinese nationals assist in converting precursors into fentanyl near the U.S. border, highlighting China's deep involvement in the manufacturing process.
