China Blocks U.S. Sanctions on Five Petrochemical Firms

Claim China imposed a ban on May 4, 2026, prohibiting recognition, enforcement, or compliance with U.S. sanctions targeting five Chinese companies allegedly involved in Iranian petroleum transactions, according to a Ministry of Commerce notice.

Evidence The Ministry of Commerce released a notice on May 4, 2026 stating that the prohibition order applies immediately and covers sanctions issued under U.S. Executive Orders 13902 and 13846, as well as related measures. The notice lists five Chinese firms, naming Shandong Shouguang Luqing Petrochemical Co Ltd and Shandong Jincheng Petrochemical Group among them. The U.S. State Department has placed these firms on the Specially Designated Nationals List, freezing assets and banning transactions.

Verdict True.

Analysis China’s ban directly counters U.S. extraterritorial sanctions that target companies for alleged participation in Iran’s oil trade. By invoking its 2021 Rules on Counteracting Unjustified Extra‑territorial Application of Foreign Legislation, Beijing frames the move as protection of sovereignty and legal rights. The order’s immediate effect means Chinese entities must ignore the U.S. asset freezes and transaction bans for the listed firms. While the ban does not alter China’s obligations under international law, it signals a willingness to confront unilateral sanctions lacking United Nations endorsement. The U.S. sanctions themselves remain in force, but any Chinese party complying with the Chinese prohibition could face secondary penalties from the United States.

What to watch next – Monitor how U.S. authorities respond to China’s defiance and whether additional Chinese firms become subject to similar bans.
