- China imports over 90% of Iran’s sanctioned oil, mostly for its small “teapot” refineries, which rely on discounted crude to remain profitable.
- Iranian crude sells at up to $11 per barrel less than similar legal alternatives, creating a lucrative but risky dependency for China’s refining sector.
- A potential Israeli strike on Iran’s Kharg Island oil terminal could disrupt up to 1.7 million barrels/day, forcing China to pay full market rates.
- Iran-China bilateral trade crossed $30 billion in 2024, but Iran is restricted to spending oil revenues in Chinese yuan, deepening its economic dependence on Beijing.
As tensions in the Middle East continue to flare, particularly with Israel’s growing military assertiveness toward Iran, one major global player is nervously watching the fallout: China. With its smaller independent refineries now deeply reliant on heavily discounted Iranian crude, any disruption in the flow of oil from Tehran could deliver a sharp economic jolt to Beijing’s energy security and financial planning.
Iran, currently under stringent U.S. sanctions, exports around 1.7 million barrels of crude oil daily — a modest figure representing less than 2% of global demand. Yet this supply is of outsized importance to China, which now purchases over 90% of Iran’s oil output, according to commodities intelligence firm Kpler.

The bulk of this crude is routed to so-called “teapot refineries” in China’s eastern Shandong province. These privately owned, non-state-affiliated plants began shifting en masse to Iranian oil in 2022 to preserve their razor-thin profit margins. The crude is often shipped using a covert “dark fleet” of vessels sailing without transponders, helping Iran sidestep sanctions enforcement and push its oil into the global market via back channels.
For Chinese refiners, Iranian oil has been a boon. In 2023, Tehran’s barrels were sold at an average discount of $11 compared to Oman Export Blend, a sanctioned-free benchmark of similar quality. The price gap narrowed to $4 in 2024, and now sits at roughly $2 a barrel, according to Argus Media’s Vice President for China Crude, Tom Reed. The shrinking discount reflects growing geopolitical concerns: conflict with Israel and renewed U.S. pressure have made the Iranian supply appear increasingly fragile.

Though Israel has so far avoided striking Iran’s oil infrastructure, several Western intelligence sources warn that this red line could soon be crossed. A strike on Iran’s Kharg Island — the key shipping terminal for its crude exports — could bring Tehran’s oil flow to a standstill. While such an act would undoubtedly rattle global markets, its consequences for China would be particularly acute.
“China has walked into an energy trap,” one Western diplomat told The Islamabad Telegraph. “It’s heavily dependent on Iranian crude that is not only sanctioned but now at risk of military disruption. Beijing would have to either pay global market rates or scramble to arrange replacement volumes.”
In monetary terms, the China-Iran oil trade has ballooned despite sanctions. Bilateral trade between the two countries surged past $30 billion in 2024, according to Chinese customs data, with oil comprising a significant portion of that figure. However, the terms of trade are skewed. Most payments are made in renminbi, not U.S. dollars, meaning Iran is compelled to spend its oil earnings primarily on Chinese goods and services — a relationship that Iranian critics have likened to a “colonial trap.”

This financial straitjacket frustrates many in Tehran. “We are exporting strategic resources for discounted prices and importing plastic and gadgets,” an Iranian oil ministry official, speaking anonymously, lamented. “But we have no other option.”
If Israel seeks to economically weaken Iran to pressure its regime, targeting energy exports would be a logical step. Still, such a move could generate blowback in Washington. Former President Donald Trump, now back in the White House and facing re-election pressures, is highly sensitive to the political risks of surging gasoline prices. Any military action that sends oil prices soaring could create economic turbulence in the U.S. just as Trump seeks to portray economic stability as a core achievement.
Analysts note that while Iran’s oil could be replaced in the broader global market, it won’t come easily. Saudi Arabia and the UAE collectively hold over four million barrels per day in spare production capacity, which they could release to stabilize markets. According to a Goldman Sachs report, the Gulf allies managed to replace up to 80% of disrupted supply in previous crises within six months.
But for Chinese refiners, the reality is starker. Losing access to Iranian crude would mean an abrupt end to years of bargain-basement oil prices. The “teapot” operators would suddenly need to procure sanctioned-free barrels at full price — significantly squeezing margins and possibly driving some smaller players out of business.
For now, Chinese policymakers remain publicly silent, but industry insiders confirm that contingency planning is underway in Beijing. “There is genuine concern in the energy sector,” a senior executive at Sinopec said. “If Iranian oil dries up, we will have to renegotiate supply deals from Russia, Iraq, or even the Gulf — all at higher prices and with stricter terms.”
As Israel-Iran tensions edge toward a potential flashpoint, the fate of Chinese refineries — and the future of China-Iran trade — may hinge on a single missile strike.
