The escalating conflict in Iran has triggered a severe disruption in global oil supplies, placing China’s carefully constructed energy security framework under unprecedented pressure. Following Iran’s threats against vessels traversing critical trade waterways in retaliation for US-Israeli strikes, Middle Eastern energy shipments have ground to a virtual standstill.
This blockade has created a worldwide oil shortage that has particularly impacted Gulf-reliant Asian economies. The Philippines has implemented mandatory four-day work weeks to conserve fuel, while Indonesia faces dwindling reserves that may last merely weeks. China, as the planet’s largest oil purchaser, is experiencing similar strains but enters this crisis from a position of relative strength due to years of strategic preparation.
The global economic landscape has been destabilized since late February when US and Israeli strikes targeted Iranian assets. Subsequent attacks on shipping infrastructure and the effective closure of the Strait of Hormuz—the world’s busiest oil transit channel—have driven prices toward $120 per barrel. Approximately 20 million barrels daily, representing one-fifth of global oil production, normally flow through this critical waterway according to U.S. Energy Information Administration estimates.
China’s energy consumption patterns reveal a complex defensive structure. The nation consumes an estimated 15-16 million barrels daily, primarily supporting its massive transportation networks. While Gulf nations historically supplied significant portions—with Saudi Arabia and Iran each contributing over 10% of imports—China has diversified its sources strategically.
Northern regions rely predominantly on domestic production and Russian pipeline imports, which remain unaffected by Middle Eastern conflicts. Russian oil now constitutes nearly one-fifth of China’s energy imports, making Moscow Beijing’s largest supplier despite Western sanctions. Furthermore, coal—abundantly available domestically—generates most of China’s electricity, with oil and gas comprising just over a quarter of the total energy mix.
Ole Hansen, Saxo Bank’s head of commodity strategy, notes that Beijing has capitalized on favorable crude prices and Gulf abundance to build one of the world’s largest oil reserves. Customs data shows a 16% year-over-year increase in crude purchases during January-February alone. Iran, despite U.S. sanctions, has been a key supplier of discounted crude, with reports indicating China purchases over 80% of Tehran’s oil exports.
Analysts estimate China maintains reserves of 900 million to 1.4 billion barrels—approximately three months’ worth of imports. Current vessel-tracking data reveals over 46 million barrels of Iranian crude sitting in South China Sea tankers, providing a substantial buffer against supply disruptions.
Nevertheless, Beijing exhibits cautionary measures, reportedly ordering refineries to halt fuel exports to stabilize domestic prices. Simultaneously, China’s aggressive renewable energy expansion has created additional insulation. Wind, solar and hydropower generated over one-third of China’s electricity in 2024, with clean sources now constituting more than half of installed capacity.
Roger Fouquet, an energy economics researcher, characterizes China’s renewable transition as both environmentally motivated and strategically economic. The proliferation of electric vehicles—comprising at least one-third of new car sales—further decouples mobility costs from oil market volatility. As Roc Shi from the University of Technology Sydney observes, ‘An EV owner in Beijing simply doesn’t feel the pain at the pump when the Middle East flares up.’
Despite these advantages, China remains vulnerable to broader economic impacts. Rising oil prices increase costs for petrochemical industries producing plastics and fertilizers, while electricity rates may climb during energy crises. As the world’s largest energy importer, China must accept higher-priced barrels—but does so from a position of prepared resilience rather than desperation.
