U.S. targets China’s shadow trade with Iran in sweeping sanctions

The Washington Post reports that the U.S. Treasury Department announced sanctions targeting Chinese entities and shipping firms involved in shadow trade facilitating Iran's oil exports, with the action timed ahead of a Trump-Xi summit. The reporting is sourced from a major national outlet with a named journalist (Cate Cadell) covering national security, and corroboration from independent search results confirms the Treasury Department sanctioned Hengli Petrochemical and 40 shipping firms and vessels—specific details that ground the reporting. The Hill and Treasury Department statements add corroborating detail on the enforcement mechanism (OFAC actions) and scope of the crackdown, while broader context from the search results shows this fits into larger U.S.-China economic tensions over sanctions evasion and financial system alternatives. Watch for the Trump-Xi summit outcome and whether these sanctions prompt Chinese policy shifts or accelerate Beijing's alternative payment systems (as noted in the NYT search result on renminbi alternatives), potentially reshaping U.S.-China economic dynamics.
