Investigators for a U.S. House committee released a report on Tuesday detailing what they describe as new evidence the Chinese government is continuing to “directly” subsidize “the manufacturing and export of illicit fentanyl.”

According to the report, Chinese officials encourage production of precursor chemicals by giving “monetary grants and awards to companies openly trafficking illicit fentanyl materials.”

Specifically, researchers found companies making fentanyl precursors and analogues could apply for state tax rebates and other financial benefits after exporting the product.
