U.S President Joe Biden and Chinese President Xi Jinping agreed earlier this week that Beijing will crack down on companies in China that produce precursor chemicals for fentanyl, an agreement that Biden said would "save lives."
In exchange, the Biden administration agreed to lift sanctions on China's Physical Evidence Identification Center of the Ministry of Public Security and the National Drug Laboratory. In May 2020, the U.S. Department of Commerce sanctioned the lab for allegedly participating in human rights violations against Uyghurs and other ethnic minorities in Xinjiang.
