Iran War Exposes China's Geopolitical Risks
The escalating U.S.-Iran war is exposing significant vulnerabilities for China, according to a new analysis. The conflict directly threatens China's energy security, as it relies on Iranian oil and stable Middle Eastern shipping lanes. This forces Beijing into a precarious diplomatic position, trying to protect its economic interests without being drawn into the conflict.
China is the single largest buyer of Iranian oil, purchasing more than 80% of Tehran's total exports in 2025. This dependency provides Beijing with discounted crude, often $8-$10 per barrel below global benchmarks, which is particularly vital for its independent "teapot" refiners. The conflict puts a spotlight on the Strait of Hormuz, the world's most critical oil chokepoint. In 2024, an average of 20 million barrels per day transited the strait, equivalent to about 20% of global petroleum consumption. Any closure would trigger simultaneous supply shocks across crude oil, LNG, and other commodities. Following the US-Israeli strikes, a high-ranking commander in Iran's Revolutionary Guards declared the strait closed and threatened that "ships of all those who want to pass will be set on fire." While vessel tracking shows some limited traffic, the withdrawal of major insurers has created a de facto closure for most commercial shipping, with insurance premiums hitting six-year highs. In response, Beijing has ramped up its diplomatic efforts. Foreign Minister Wang Yi condemned the strikes as a violation of international law, and a ministry spokesperson has repeatedly called for the safety of shipping lanes to be maintained. China has explicitly stated it will take necessary measures to safeguard its own energy security. Behind the scenes, China is reportedly pressuring Tehran to avoid disrupting energy shipments from Qatar. Qatar is the world's second-largest LNG producer and supplies about 30% of China's LNG imports, the majority of which must pass through the Strait of Hormuz. To weather potential disruptions, China has been aggressively stockpiling. As of early 2026, government-controlled stockpiles were estimated at around 900 million barrels, equivalent to about 78 days of imports. Recent record shipments from both Iran and Russia have further cushioned its refiners from short-term shocks. Though Iran is a key energy partner, the relationship is asymmetric. Iran accounts for less than 1% of China's total trade, and while it supplies about 13% of China's seaborne crude imports, Iran depends on China to buy 80% of its oil exports. Some analysts view the US strategy as a way to exert indirect pressure on China. By targeting energy states aligned against Washington, the U.S. can reshape global energy leverage, creating economic and geopolitical liabilities for Beijing without direct confrontation.
