China has taken a bold step ahead of President Trump's meeting with Chairman Xi Jinping in Beijing, issuing a directive that explicitly prohibits Chinese citizens, companies, and organizations from complying with U.S. sanctions on Iranian trade. The Ministry of Commerce's Announcement No. 21, published on May 2, includes three clear directives: "shall not recognize," "shall not enforce," and "shall not comply with" U.S. Executive Orders 13902 and 13846, which target entities trading with Iran.

This move marks the first activation of China's 2021 Rules on Counteracting Unjustified Extra-Territorial Application of Foreign Legislation. The directive now allows Chinese entities to sue foreign banks, traders, insurers, or shippers that cut off business ties to comply with U.S. sanctions, creating a private right of action in Chinese courts.

The implications extend well beyond Beijing. China leads the BRICS, and the BRICS will follow Beijing’s template.

Timing as a Message

The timing of the announcement is no coincidence. Released just days before the Beijing summit, it serves as a clear signal to the U.S. delegation that China intends to rewrite the rules of engagement. This move challenges Washington's long-standing assumption that no major counterparty would counterattack against U.S. sanctions.

With this action, Beijing has transformed its statutes from a "paper tiger" into a tool with real teeth, signaling a new phase in U.S.-China relations where sanctions may no longer be an uncontested card in Washington's hand.
