On May 3, 2026, China took decisive action by blocking US sanctions against five refiners accused of importing Iranian oil, a move that underscores its strategic positioning in global energy security amidst rising tensions in the Middle East.
These refiners, which include major players like Hengli Petrochemical and Shandong Jincheng Petrochemical Group, face restrictions that bar them from accessing the US financial system. In response, China’s Ministry of Commerce issued a prohibition order against these sanctions, emphasizing that such measures improperly restrict business between Chinese enterprises and third countries.
That context matters because China heavily relies on oil imports from the Middle East, with over half of its oil sourced from this region, much of it coming from Iran. In fact, in 2025, China purchased more than 80 percent of the oil shipped from Iran. This relationship is crucial for China’s energy independence and reflects its ongoing efforts to secure stable energy supplies amid geopolitical tensions.
Moreover, China’s teapot refineries account for a significant portion—about a quarter—of its total refinery capacity. As these refiners continue operations despite US pressure, they play a pivotal role in meeting domestic demand while also contributing to the nation’s overall energy strategy.
But how does this intersect with broader trends? The conflict in the Middle East has led to notable increases in global energy prices. For instance, crude oil prices have surged by approximately 70 percent since hostilities escalated. This volatility presents both challenges and opportunities for China as it navigates its energy landscape.
In addition to oil imports, China has been expanding its investments in clean energy technologies. The closure of critical shipping routes has prompted discussions about shifting towards electric vehicles (EVs). The Secretary-General of the China Passenger Car Association noted that this situation presents a significant opportunity for Chinese EVs to replace gasoline-powered vehicles.
Recent orders by airlines like China Southern Airlines and Xiamen Airlines for 137 Airbus A320neo jets further illustrate China’s commitment to enhancing its aviation sector while potentially reducing reliance on foreign technology. This diversification aligns with China’s broader goals of achieving greater self-sufficiency across various industries.
The stakes are high as China continues to oppose unilateral sanctions lacking UN authorization. As stated by China’s Ministry of Commerce, such actions violate international law and basic norms governing international relations. With strategic oil stockpiles estimated at around 1.4 billion barrels at the start of the ongoing conflict, China appears well-prepared to weather potential supply disruptions.
