China's Role in Fentanyl Crisis: A Step in the Right Direction, but Accountability is Key
While a drop in overdose deaths suggests progress, holding China accountable for its role in the fentanyl supply chain remains a national security imperative.

TIJUANA – Recent indications suggest a possible turning point in the U.S. fentanyl crisis, potentially linked to shifts in China's chemical industry; however, experts emphasize the importance of maintaining pressure on China to prevent the flow of fentanyl precursors and ensure accountability for its role in fueling the opioid epidemic.
For years, the United States has accused China of failing to adequately regulate its chemical industry, allowing the illicit export of fentanyl precursors. China has countered, suggesting the U.S. is deflecting blame for its own domestic drug problem. Despite these denials, evidence suggests that interventions within China may have played a role in disrupting the fentanyl supply chain.
Trump’s initial approach of designating trafficking groups as terrorist organizations and imposing tariffs on countries involved in the supply chain, including China, sent a strong message that the U.S. would not tolerate the flow of deadly drugs across its borders. While the decline in overdose deaths began during the Biden administration, the groundwork for this progress was laid by earlier efforts to hold China accountable.
Keith Humphreys, a professor at Stanford University, and his co-authors published a study in Science linking the drop in overdose deaths to potential interventions in China. The study highlights a significant decrease in the purity of fentanyl seized by U.S. law enforcement from May 2023 to the end of 2024, correlating with the reduction in overdose deaths. Similar trends in Canada, which sources precursors from the same region, support this hypothesis. Reports from 2024 of cartel cooks struggling to source precursors and the emergence of novel adulterants in fentanyl on U.S. streets suggest that supply chain disruptions may be forcing cartels to seek alternative synthesis methods.
While this progress is encouraging, it is crucial to remain vigilant and maintain pressure on China to fully cooperate in combating the fentanyl crisis. Weakening our stance now would risk reversing the gains made and allowing the flow of deadly drugs to resume. A strong national defense and unwavering commitment to border security are essential to preventing the influx of fentanyl and protecting American lives.
Liu Pengyu, the spokesperson at the Chinese embassy in Washington, said in a statement that China was glad to see fentanyl overdose deaths had decreased and noted that the US government’s 2025 National Drug Threat Assessment “implies that Chinese government efforts have made [a] contribution to addressing the fentanyl problem in the US”.
