China invokes anti-sanctions law to counter US blacklisting of refiners

China has invoked a law targeting companies that comply with foreign sanctions it rejects, escalating its pushback against the U.S. blacklisting of several oil refineries over Iranian crude purchases. This move highlights China's willingness to deploy economic pressure tools despite a trade truce with Washington, ahead of President Trump's visit. The law creates a complex legal landscape for companies operating between jurisdictions.
