What Happened
- Following the US-Israeli airstrikes on Iran on February 28, 2026 — which killed Iran's Supreme Leader — Iran retaliated by attacking US military bases across the Middle East and Israeli military facilities.
- Iran subsequently announced restrictions on commercial navigation through the Strait of Hormuz, the world's most critical oil transit chokepoint, directly threatening China's energy supply chains.
- Before the conflict, China received approximately 5.35 million barrels of oil per day via the Strait of Hormuz; this has dropped sharply with the waterway now effectively restricted.
- China had imported 1.38 million barrels per day from Iran in 2025 (about 12% of total Chinese crude imports), making Iran a strategically significant — though politically sensitive — supplier.
- China finds itself in a difficult position: as Iran's primary economic lifeline and the largest buyer of sanctioned Iranian oil, it has strong incentives to de-escalate, but its leverage over Iran is limited.

China's Energy Security and Oil Import Dependence
China is the world's largest oil importer, importing over 10 million barrels per day. Despite rapid expansion of renewables and electric vehicles, China remains heavily dependent on fossil fuel imports to power its manufacturing economy. The Middle East supplies more than half of China's crude oil imports, and the Strait of Hormuz is the primary transit route.
- China's share of Strait of Hormuz oil flows: 37.7% — the largest recipient globally (Q1 2025)
- Iran-China oil trade: China imported ~1.38 million b/d from Iran in 2025, most relabelled as "Malaysian" crude to circumvent US sanctions
- China-Iran 25-Year Cooperation Agreement (2021): $400 billion deal covering energy, infrastructure, and military cooperation
- China's strategic petroleum reserves (SPR): estimated 1.2 billion barrels as of January 2026 — providing a buffer of approximately 90+ days
- By 2030, China aims to increase non-fossil fuel share to 25% of total energy (from 21.7% in 2025)
Connection to this news: China's energy security is more directly threatened by the Iran war than that of almost any other major economy. With 50% of its oil imports and nearly one-third of its LNG imports transiting the Strait of Hormuz, the conflict forces China to choose between its economic interests (stable energy flows) and its geopolitical alignment with Iran and Russia.
US-China Strategic Competition and the Iran Dimension
The US-China rivalry has multiple dimensions — trade, technology, Taiwan, and now the Middle East. Iran has been a key node in the China-Russia-Iran axis that challenges US primacy. China has used Iran to diversify energy suppliers, circumvent dollar-based financial systems, and demonstrate its willingness to defy US sanctions extraterritorially.
- CAATSA (Countering America's Adversaries Through Sanctions Act, 2017): US law threatening secondary sanctions on China for Iranian oil purchases
- Shanghai Cooperation Organisation (SCO): Iran joined as a full member in 2023, joining China, Russia, India, and others
- Belt and Road Initiative (BRI): Iran is a BRI participant; Chinese infrastructure investments in Iran exceed $10 billion
- US dollar dominance: China has been developing CIPS (Cross-Border Interbank Payment System) partly to facilitate non-dollar trade with sanctioned states like Iran
- Yuan-denominated oil trade: China has pushed for petro-yuan settlements, particularly with Iran and Russia
Connection to this news: The US-Israel strike on Iran forces China to choose between defending its strategic partner (risking confrontation with the US) and protecting its economic interests (energy flows, trade routes). China's response will test the US-China relationship at a critical juncture.
Qatar LNG and Asia's Energy Vulnerability
Qatar is the world's largest exporter of Liquefied Natural Gas (LNG), and all its LNG shipments transit the Strait of Hormuz before reaching Asia. Asia accounts for approximately 70% of global LNG demand, with China, Japan, South Korea, and India as the top importers. A prolonged Hormuz closure would simultaneously cut oil and LNG flows to Asian economies.
- Qatar LNG exports: approximately 77 million metric tonnes per year (2024) — about 22% of global LNG supply
- China imports approximately 16 million tonnes of Qatari LNG annually
- LNG price benchmarks: JKM (Japan Korea Marker) for spot LNG in Asia — highly sensitive to supply disruptions
- Qatar-China LNG deal (2022): 27-year agreement for 4 million tonnes/year of LNG
- India's LNG imports: ~27 million tonnes/year, of which 60% comes from the Middle East including Qatar
Connection to this news: Beyond oil, Qatar's LNG shutdown following the Iran conflict creates a simultaneous gas supply crisis for China and other Asian economies, demonstrating how concentrated energy transit through Hormuz creates cascading systemic risks across the energy complex.
