The US Drug Enforcement Administration is shutting down two of its hard-won offices in China, the AP has learned—a move that comes even as the agency struggles to disrupt the flow of precursor chemicals from the country that have fueled a fentanyl epidemic in the US. "These closings reflect the need to harness [the] DEA's limited and strained resources to target where we can make the biggest impact in saving American lives," DEA Administrator Anne Milgram told agents in an email last week that also included plans to close a dozen other offices worldwide to trim DEA's current footprint of 93 offices in 69 countries.
