Bloomberg reports that China's commerce ministry has ordered domestic companies not to comply with U.S. sanctions targeting five Chinese refiners linked to Iranian oil imports, invoking a blocking statute for the first time since its adoption in 2021. The order, issued Saturday, bans recognition, enforcement, and compliance with the U.S. measures, and allows the affected refiners — including Hengli Petrochemical (Dalian) Refinery Co. — to seek compensation in Chinese courts from any entity that does comply. Eurasia Group analysts warned that if Washington extends secondary sanctions to Chinese banks or major state-owned entities, Beijing would likely escalate with more forceful countermeasures.
