Trump threatens tariffs on China over fentanyl crisis allegations

U.S. President-elect Donald Trump has threatened new tariffs on Chinese goods, citing China's alleged role in the fentanyl crisis. The U.S. claims that Chinese chemical components are used to produce fentanyl in Mexico, which is then smuggled into the U.S. While China denies these accusations, U.S. officials say it remains a major source of fentanyl-related substances. Stricter controls in China since 2019 have shifted the supply chain, with chemicals now sent to Mexico for production instead of direct shipments to the U.S. Recent talks between the U.S. and China on drug control have resumed after a summit between President Biden and President Xi Jinping. China has agreed to regulate key fentanyl precursors, but experts warn that traffickers may adapt quickly to new restrictions.
