The Iran war is winding down, and Beijing is taking notes. As Foreign Policy’s James Palmer writes in his China Brief newsletter this week, the lessons China draws from the conflict will shape its strategic posture across the Middle East and beyond for years to come.
The war exposed something China has long tried to manage rather than confront: the vulnerability of depending on the Strait of Hormuz for roughly 30 percent of its crude oil imports. When Iran closed the waterway in February, Beijing could do little more than issue diplomatic statements and watch its energy security hang on the outcome of a conflict it did not control.
China’s response to the war was defined by restraint. It condemned the US-Israeli strikes on Iran publicly but did not commit troops, did not break diplomatic relations, and did not impose counter-sanctions. It abstained from United Nations Security Council Resolution 2817, which condemned Iranian attacks on Gulf states, choosing a middle path that preserved deniability on all sides. Beijing dispatched envoys for mediation and evacuated its nationals from Iran, but it never came close to military involvement.
The calculus was brutally practical. China imports more than 80 percent of Iran’s shipped oil under normal conditions. It had extensive pre-war commercial ties — Chinese firms supplied radar systems, navigation technology, and chipmaking tools to Iranian entities. But those relationships were not worth a war with the United States. So China watched, waited, and kept its powder dry.
Now the war is ending, and the calculation shifts.
Courting Iran’s new power brokers
Before the war, Beijing maintained strong ties with Iran’s political establishment but had comparatively weaker connections to the Islamic Revolutionary Guard Corps. That balance has shifted. The IRGC, now led by a new generation after the death of Qassem Soleimani’s successors and the killing of Supreme Leader Ali Khamenei, has emerged as the dominant force within Iran’s post-war power structure.
China will move quickly to correct its network gap. Chinese firms already have some links to IRGC-controlled enterprises through joint ventures in construction, telecommunications, and energy. Expect those ties to deepen rapidly as Beijing positions itself as Iran’s indispensable post-war partner — the one great power that did not bomb them, did not sanction them, and is ready to help rebuild.
Energy diversification becomes strategic imperative
The Hormuz closure was a wake-up call that no amount of diplomatic hedging could obscure. China depends on a single narrow waterway for too much of its energy supply, and a hostile US Navy can shut it down at will. The lesson: diversify supply routes, build strategic reserves, and develop alternatives.
China has already been investing in overland pipelines from Russia and Central Asia, but the volumes are a fraction of what moves through Hormuz. It has been stockpiling crude in strategic reserves, but those reserves were drawn down during the war and need replenishing. It has accelerated investment in renewable energy at home, but the transition takes years.
The war will accelerate all three tracks. Expect Beijing to push harder for the Russia-China Power of Siberia 2 pipeline, expand storage capacity, and fast-track domestic energy transitions. The goal is not to eliminate Hormuz dependence — that is not possible in the short term — but to reduce the leverage the US can exert through the waterway.
Military lessons: what not to do
China’s military observers watched Operation Epic Fury closely. The US-Israeli campaign demonstrated that precision airstrikes can decapitate a leadership, destroy nuclear infrastructure, and crater a military command structure in a matter of hours. But it also showed that tactical superiority does not produce strategic victory.
Iran survived. Its missile forces — damaged but not destroyed — proved capable of striking targets across the region. Its ability to close the strait turned economic warfare into a weapon. And its regime held together despite the loss of the supreme leader.
The lesson for China is not that the US is unbeatable. It is that the US is beatable in a way that does not mirror China’s own vulnerabilities. A Taiwan contingency would not involve a strait China could close — it would involve a strait the US would close against China. The military lesson is not about copying Iran’s tactics but about understanding that asymmetric power — the ability to impose costs the adversary cannot absorb — works better than conventional parity.
Diplomatic positioning
China also learned that neutrality pays. By staying out of the fighting, refraining from direct criticism of either side, and offering mediation services, Beijing emerged from the conflict with its relationships largely intact. It can now step into the post-war reconstruction phase as a natural partner for Iran, a commercial competitor for Western firms in Gulf reconstruction, and a diplomatic alternative for states that do not want to align fully with Washington.
The Iran war was a crisis China did not choose, could not control, and can now exploit. The question is whether the lessons Beijing draws from it — diversify energy, deepen ties with Iran, avoid direct confrontation with the US — add up to a coherent strategy or merely a set of tactical responses.
If history is any guide, China will pursue all of them at once and call the resulting contradictions “flexibility.”
