China has announced counter-sanctions in response to US measures imposed on five Chinese companies accused of involvement in Iran’s oil trade. Beijing formally issued an injunction to block the US sanctions, which Washington said were aimed at firms violating its Iran-related restrictions. The Chinese Ministry of Commerce denounced the US move as an example of “long-arm jurisdiction.”

According to China’s state news agency Xinhua, the sanctioned companies include Hengli Petrochemical (Dalian) Refinery, Shandong Jincheng Petrochemical Group, Hebei Xinhai Chemical Group, Shouguang Luqing Petrochemical, and Shandong Shengxing Chemical. The details of how Beijing’s injunction will be implemented have not yet been clarified.

Analysts cited in the report noted that this latest dispute over Iran could further complicate the already tense trade and diplomatic relations between Washington and Beijing.
