Beijing strikes back: China invokes first-ever "blocking order" against US sanctions

Beijing issues first-ever blocking order to protect five petrochemical firms from US sanctions over Iranian oil trade, escalating trade hostilities.

"The Chinese government firmly opposes unilateral sanctions that are not authorised by the United Nations or grounded in international law. - Chinese MOC Spokesperson"

Beijing, May 2

In a sharp escalation of trade hostilities, China's Ministry of Commerce on Saturday issued a formal blocking measure prohibiting domestic entities from complying with US sanctions, Xinhua reported.

The move specifically protects five major Chinese petrochemical firms recently targeted by Washington for their alleged involvement in the Iranian oil trade.

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

According to Xinhua, the companies named 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 the firms on the Specially Designated Nationals (SDN) list, freezing their assets, and restricting transactions with them.

Responding to the sanctions, an MOC spokesperson said the United States has, since 2025, imposed restrictions on the Chinese companies under its executive orders targeting other countries, citing their alleged role in petroleum dealings with Iran, Xinhua reported.

The spokesperson criticised the US actions, stating that such measures improperly restrict normal economic and trade exchanges between Chinese companies and third countries, as well as their citizens and organisations, in violation of international law and basic norms governing international relations.

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 continue to play a significant role in importing and processing Iranian crude oil, including throughout 2026.

The OFAC designated the above-mentioned five refineries as part of its enforcement actions.

Before this alert, the OFAC imposed sanctions on "teapot" refinery Hengli Petrochemical (Dalian) Refinery Co., Ltd., citing its role in purchasing large volumes of Iranian crude oil and petroleum products.

According to the Treasury Department, the refinery is among the major buyers supporting Iran's oil economy, having reportedly purchased billions of dollars' worth of Iranian petroleum.

The Chinese Commerce Ministry further stated that the blocking order was issued in accordance with Beijing's rules on countering the extraterritorial application of foreign laws, to safeguard national sovereignty, security and development interests, and protect 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.

Interesting how China is using legal countermeasures now instead of just protesting. These "teapot" refineries in Shandong are clearly crucial for Iran's oil revenue, but the US sanctions are also hurting smaller economies like ours. India must avoid getting caught in this crossfire—we need to balance our energy needs with international obligations.

While I support any nation's right to defend its sovereignty, this escalation is worrying for global trade stability. The US sanctions are clearly an overreach, but China's blocking order could set a precedent for other countries like India to enact similar laws if needed. However, we must remember that such moves can also backfire—the world is too interconnected for unilateral actions. 🇮🇳

China is smart—using its legal system to counter US pressure is a strategic move. But India should also learn from this: we need stronger mechanisms to protect our businesses from foreign sanctions, especially given our own oil imports from Iran. The US might target Indian companies next, so we better be prepared.

This is a classic example of major powers using economic tools as weapons. The "teapot" refineries are just pawns in a larger game. For India, the lesson is clear: diversify our energy sources and reduce dependence on any single route. Sam, India should also consider how to leverage our position as a neutral player in these conflicts. 😌

China's move is bold, but let's be honest—these blocking orders often have limited practical effect. The US controls the global financial system
