China responded by issuing a formal legal order that declares these U.S. sanctions null and void inside China. The order also prohibits Chinese companies from complying with the sanctions.

This action represents the first time China has formally activated its Blocking Rules, a mechanism created in 2021. The rules were designed to address such scenarios involving foreign sanctions.

As a result, banks, shippers, and multinational companies operating in China now face conflicting legal obligations. They must choose between complying with U.S. requirements or Chinese regulations.

2025, China purchased 80% of Iran's exported oil, as reported by @MarioNawfal. The U.S. sanctions aim to enforce a financial blockade on Iran. This development creates a significant challenge to those efforts.
