Exovera’s report, Chinese and Taiwanese Chemists Involved in Drug Production and Trafficking from China to Latin America, explores how individuals with chemistry and pharmaceutical expertise have become central actors in the global synthetic drug trade. Chinese and Taiwanese nationals have leveraged ties to chemical companies and organized crime groups to produce illicit substances, export precursors, and collaborate with cartels such as the Jalisco New Generation and Sinaloa cartels. The report profiles cases across China, Mexico, Paraguay, and the United States, including chemists such as Hsu Yung Cheng, who ran Paraguay’s first clandestine meth lab; Ye Chuanfa, indicted as head of Wuhan’s Yuancheng Group for exporting fentanyl precursors; and Wang Bin, who managed the U.S. distribution hub for the Zheng Drug Trafficking Organization. Others, including Zhang Zhi Dong and Chiang Li Chun, acted as logistics intermediaries funneling chemicals into Mexico for cartel production.
Within China, trained professionals such as Li Hao, Zhang Zhengbo, and Wang Bo applied their scientific knowledge to manufacture and innovate new psychoactive substances for global export. Despite diverse backgrounds—ranging from professors and entrepreneurs to elite graduates—these chemists were united by the lure of financial gain and their willingness to collaborate with transnational criminal organizations. Their expertise in modifying chemical formulas and managing cross-border supply chains has made them indispensable enablers of the fentanyl and synthetic drug economy. The report concludes that these actors represent a human chokepoint in the drug trade and warrant closer monitoring by international law enforcement.
