China Issues Injunction to Block US Sanctions on Domestic Refiners

China has issued a formal injunction blocking US sanctions on five domestic refiners accused of purchasing Iranian oil, calling it a "defensive and justified response." Writer Li Yang argued the US sanctions lack UN authorization and violate international law, marking a shift from diplomatic protests to legal countermeasures. This is the first time Beijing has invoked its "blocking statute" to neutralize extraterritorial US laws, protecting companies like Hengli Petrochemical. The move follows US Treasury warnings about Chinese "teapot" refineries in Shandong province that have continued importing Iranian crude throughout 2026.

"Defensive and justified": China issues formal injunction to block "illegal" US sanctions on domestic refiners

China issues formal injunction to block US sanctions on five domestic refiners accused of buying Iranian oil, calling it a "defensive and justified response" violating international law.

"Chinese entities are not to comply with illegal US sanctions - Li Yang"

Beijing, May 3

The Chinese government has issued a formal injunction to block US sanctions directed at five domestic refiners, including the Hengli Petrochemical Refinery, accused by Washington of purchasing Iranian oil.

China Daily, a state-affiliated English-language outlet, defended Beijing's decision by describing the move as a "defensive and justified response" to what the government characterises as a clear violation of international law.

In an analysis for the outlet, writer Li Yang argued that the sanctions imposed by Washington lack the necessary authorisation from the United Nations. Consequently, Li asserted that such measures "violate international law and the basic norms of international relations."

He further contended that the US "is not merely targeting specific companies" but is actively attempting to assert "jurisdiction over third-party trade between sovereign actors."

Connecting this to broader geopolitical strategies, Li noted that the US has historically utilised the global dominance of the dollar to expand the reach of its domestic policies. He observed that "secondary sanctions penalising entities that transact with blacklisted parties have become a staple of US statecraft."

According to the report, China's judicial and administrative response serves to establish a firm boundary against external interference. Li concluded that the injunction sends a definitive message that "Chinese entities are not to comply with illegal US sanctions."

In a sharp escalation of trade hostilities, China's Ministry of Commerce (MOC) on Saturday formalised this stance by issuing a blocking measure prohibiting domestic entities from complying with the US restrictions, Xinhua reported.

This marks the first time Beijing has officially invoked its "blocking statute," a legal mechanism designed to neutralise the extraterritorial reach of foreign laws, signaling a shift from diplomatic protests to active legal countermeasures.

According to Xinhua, the specific companies named under this protection include Hengli Petrochemical (Dalian) Refining Co., Ltd., Shandong Shouguang Luqing Petrochemical Co., Ltd., Shandong Jincheng Petrochemical Group Co., Ltd., Hebei Xinhai Chemical Group Co., Ltd., and Shandong Shengxing Chemical Co., Ltd.

As per the Chinese MOC, the US measures involve placing these firms on the Specially Designated Nationals (SDN) list, freezing their assets, and restricting transactions with them.

An MOC spokesperson criticised the US actions, stating that such measures improperly restrict normal economic and trade exchanges between Chinese companies and third countries. The spokesperson added that these actions target citizens and organisations in violation of international law and basic norms governing international relations, Xinhua reported.

The Chinese response follows a period of heightened scrutiny from Washington. Last month, the US Department of the Treasury's Office of Foreign Assets Control (OFAC) cautioned global financial institutions about the sanctions risks associated with dealings involving independent Chinese oil refineries, commonly known as "teapot" refineries, particularly those based in Shandong province.

According to an alert by the OFAC, these refineries have continued to play a significant role in importing and processing Iranian crude oil throughout 2026. The Treasury Department has identified these refineries as major buyers supporting Iran's oil economy, having reportedly purchased billions of USD worth of Iranian petroleum.

The Chinese Commerce Ministry stated that the blocking order was issued in accordance with Beijing's rules on countering the extraterritorial application of foreign laws. The measure aims to safeguard national sovereignty, security, and development interests while protecting the legitimate rights of Chinese entities, as reported by Xinhua.

Reiterating its position, the spokesperson said the Chinese government firmly opposes unilateral sanctions that are not authorised by the United Nations or grounded in international law.

While I understand China's frustration, this is a slippery slope. Secondary sanctions are designed to enforce US foreign policy, and ignoring them could have serious consequences for global trade. But I also think the US overreaches sometimes. It's complicated. 🤔

Ye to bahut interesting hai! China finally using its blocking statute. India should take notes - we have similar issues with CAATSA and Russian S-400 deal. Why should America decide who we trade with? The world is not unipolar anymore. China is showing the way to challenge US hegemony. 🇨🇳🇮🇳

China's argument about UN authorization is weak. The US has used secondary sanctions for decades, and they are a legitimate tool of foreign policy. Iran is a state sponsor of terror - every country should help isolate them, not buy their oil. China is just protecting its own economic interests, not standing for international law.

Finally someone is standing up to US bullying! They impose sanctions on everyone - Russia, Iran, now Chinese companies. But when it comes to Israel or Saudi Arabia, they look the other way. Hypocrisy at its finest. China is right to protect its companies. India should follow suit. We need our own blocking statute. 💪

Interesting development but I hope this doesn't escalate into a full-blown trade war. China is the world's largest oil importer, and Iran needs buyers. This could destabilize global oil markets. The US should negotiate instead of threatening. Both sides need to be pragmatic.
