One focus of the talks was fentanyl, the synthetic opioid that is ravaging America, and in particular ingredients for the drug that are made in China. The U.S. wants China to do more to curb the export of chemicals that it says are processed into fentanyl, largely in Mexico, before the final product is smuggled into the United States. But China refused to discuss cooperation unless the U.S. lifted sanctions on the Public Security Ministry's Institute of Forensic Science. The U.S. quietly agreed to lift the sanctions to get cooperation on fentanyl. State Department spokesperson Matthew Miller called it “an appropriate step to take” given what China was willing to do on the trafficking of fentanyl precursors.
