- China now purchases nearly 100% of Iran’s oil output (~1.4M bbl/day), up from ~25% in 2018, creating a financial lifeline that has blunted the impact of Western sanctions
- The trade flows through an elaborate network of teapot refineries in Shandong, state-linked Bank of Kunlun, shadow tanker fleets, and Hong Kong front companies — totaling $8.4B in infrastructure-for-oil barters in 2024 alone
- Iran has used oil revenues to fund Hezbollah, Hamas, the Houthis, and its own expanding arsenal of ballistic missiles and drones
- U.S. and Israeli officials now argue that severing this economic pipeline — including secondary sanctions on Chinese banks and refiners — must be central to any strategy to degrade Iran’s military capacity
What Happened?
China has quietly become the backbone of Iran’s sanctioned economy, purchasing nearly all of Iran’s oil output through a sophisticated web of intermediaries and shell companies. Investigations by the WSJ reveal that the trade — worth an estimated $8.4 billion in infrastructure deals in 2024 alone — flows through small “teapot” refineries in Shandong province, state-linked Bank of Kunlun, and a shadow fleet of tankers registered through Hong Kong front companies. Since U.S. sanctions intensified, China’s share of Iranian oil imports has surged from roughly 25% in 2018 to nearly 100% today, effectively making Beijing the sole buyer keeping Iran’s economy afloat.
Why It Matters?
The arrangement has given Iran the financial runway to arm and fund proxy forces across the Middle East — Hezbollah in Lebanon, Hamas in Gaza, the Houthis in Yemen — alongside its own expanding arsenal of ballistic missiles and drones. For Beijing, discounted Iranian crude has been a strategic windfall, insulating China from global energy market volatility while deepening its regional leverage. U.S. and Israeli officials now argue that cutting this economic lifeline is a prerequisite for any lasting reduction in Iranian military power, and that aggressive pressure on China’s teapot refiners and financial intermediaries must be a central pillar of that strategy.
What’s Next?
Both the Biden and Trump administrations sanctioned entities involved in the Iran-China oil trade, with limited effect. U.S. officials are now weighing more aggressive secondary sanctions targeting Chinese banks and refiners that continue handling Iranian crude. China has consistently denied facilitating sanctions evasion and is unlikely to cooperate voluntarily. With the Strait of Hormuz closed and global oil prices elevated, pressure on both Tehran and Beijing is rising — but so is China’s incentive to keep the discounted-oil pipeline alive for as long as possible.
