January 31, 1963 - Zhenli Ye Gon

His case sits at the intersection of pharmaceutical commerce and drug trafficking infrastructure, illustrating how legitimate import businesses can allegedly serve as conduits for precursor chemicals that fuel methamphetamine production at scale. The allegations center on a narrow but significant slice of his company's import activity — four shipments out of nearly three hundred — yet the U.S. government's indictment framed those shipments as part of a broader conspiracy reaching across the border. The volume of pseudoephedrine allegedly involved, and the transnational scope of the supply chain, drew sustained attention from both Mexican and American law enforcement through the late 2000s.

From Wikipedia

Zhenli Ye Gon (born January 31, 1963, in Shanghai) is a Chinese-Mexican businessman currently under suspicion of trafficking pseudoephedrine or ephedrine precursor chemicals into Mexico from Asia. He is the owner and legal representative of Unimed Pharm Chem México, as well as various other Mexican corporations. From 2002 to 2004, Unimed had been legally authorized by the Mexican government to import thousands of metric tons of pseudoephedrine and ephedrine products into Mexico, as a part of its vast importation business. Pseudoephedrine and ephedrine products at the time were widely used in over-the-counter cold medications such as Sudafed, but could also be used by manufacturers of methamphetamine.

Audits conducted by Mexican officials between 2002 and 2006 at Unimed showed no improprieties such as improper diversion of any such chemicals. Nevertheless, after Unimed's license to import pseudoephedrine and ephedrine products ended on July 1, 2005, it was alleged that Ye Gon and certain employees of his violated the law by continuing to import four unauthorized containers of pseudoephedrine or ephedrine precursor chemicals into Mexico in late 2005 and 2006. Only 4 of Unimed's 291 imported shipments (from Canada, China, England, Germany, Israel, Hong Kong and the United States) into Mexico have ever been questioned. In July 2007, the U.S. government filed an indictment charging that the importation of these four shipments into Mexico was part of a conspiracy to aid and abet the importation of methamphetamine into the United States.
