At the G-20 summit in Buenos Aires in December, U.S. President Donald Trump announced that his Chinese counterpart, Xi Jinping, had agreed to tighten China’s controls over manufacturing fentanyl, a powerful synthetic opioid that is orders of magnitude stronger than heroin.

Yet over the past four years, illicit fentanyl, much of it produced in China and mailed to U.S. buyers, has emerged as the major driver of fatal overdoses in the United States. In 2013, the National Forensic Laboratory Information System, which collects information on drugs seized and identified by U.S. law enforcement, had only 934 reports of fentanyl. The next year, it had more than 5,000 reports of fentanyl and in 2017, nearly 59,000.
