China Tightens Controls on Fentanyl Precursors After Summit

China has announced new regulations requiring licenses for the export of 13 chemicals used to produce fentanyl, a significant move in the ongoing battle against the opioid crisis. This decision is seen as a response to thawing tensions between China and the United States, as much of the fentanyl precursors are shipped from China to Mexico, where drug cartels process the drug before smuggling it into the U.S. The tightening of controls on these chemicals may help curb the flow of fentanyl and its devastating impact on public health, marking a potential shift in international cooperation on drug trafficking issues.
