Operation Smoking Dragon

Charges against the subjects included smuggling real and phony drugs and other contraband into the U.S. along with counterfeit $100 bills—believed to have been produced in North Korea—that were so nearly perfect and so much more sophisticated than typical counterfeit currency they were dubbed “Supernotes.”

The eight-year investigation began when FBI undercover agents, posing as underworld criminals, helped make sure that shipping containers full of counterfeit cigarettes made it past U.S. Customs officers undetected. Over time, as undercover agents won the smugglers’ trust, they were asked to facilitate other illegal shipments such as narcotics and millions of dollars in Supernotes. Later, the smugglers offered a variety of Chinese military-grade weapons, including the QW-2 surface-to-air missiles.
