Biden will discuss the issue with China's President Xi Jinping on Wednesday in San Francisco at the Asia-Pacific Economic Cooperation (APEC) forum. U.S. National Security Advisor Jake Sullivan said on Tuesday that Washington hoped the summit would result in action to help combat the fentanyl trade. China has long questioned why the U.S. would expect cooperation on fentanyl while targeting the institute. China's embassy in Washington did not immediately respond to a request for comment on the fentanyl issue. Fentanyl is up to 50 times stronger than heroin and is increasingly mixed with other illicit drugs, often with lethal results.
