How Does the Iran War Affect China’s Energy Security?

China imports over 10% of its oil from Iran, most of it routed through the Strait of Hormuz, and the ongoing Iran‑U.S. conflict threatens to choke that corridor. While oil accounts for less than one‑fifth of China’s total energy consumption, the country remains 85% self‑sufficient thanks to abundant coal and a rapidly expanding renewable base. A prolonged closure of the strait—beyond three months—would test Beijing’s diversification strategy and could force diplomatic pressure on the United States. Nonetheless, China’s broader energy mix and supplier diversification limit the immediate security risk.
