The fentanyl crisis remains a pivotal issue in U.S.-China trade discussions. While America grapples with its devastating opioid epidemic, the question persists: is China truly the root cause? Anthony Chan, former JPMorgan Chase chief economist, contends that fentanyl-related tariffs will disappear once U.S. overdose deaths approach zero. Professor Liu Baocheng of the University of International Business and Economics argues that the solution lies in America strengthening its "last-mile" enforcement against illegal manufacturing and smuggling networks. China stands ready to collaborate on this global challenge but maintains that legitimate pharmaceutical trade must be safeguarded.
