China's Silence on the Iran War Is a Strategy — But It Has a Cost

China calls Iran a "strategic partner." So where is Beijing now that Iran is at war with the United States and Israel?

The Calculation Behind the Quiet

As U.S. Navy F/A-18s operate from the USS Abraham Lincoln in support of Operation Epic Fury and Israeli strikes continue against Iranian targets, the world's second-largest military power has chosen a conspicuous posture: strategic silence.

Dr. Yoram Evron, associate professor of Political Science and Chinese Studies at the University of Haifa and senior fellow at the Begin-Sadat Center for Strategic Studies, argues this silence is neither indifference nor weakness. It is, in fact, Beijing's most rational available move — for now.

China's first concern is energy. The Persian Gulf supplies a substantial share of China's crude oil imports, and any escalation that disrupts shipping lanes or destabilizes Gulf producers could send prices sharply upward. For a country managing significant domestic economic headwinds, that's not an abstract risk — it's a threat to social stability.

The second concern is assets and people. Past conflicts in the region have cost Chinese firms billions of dollars. Beijing has grown increasingly attentive to protecting its nationals and commercial interests abroad, and a widening war puts both at risk.

The third concern is the most structurally important: China has spent years cultivating relationships with virtually every major power in the Middle East simultaneously — Iran, Saudi Arabia, the UAE, Israel, and others. Visibly backing Tehran would jeopardize relationships with Riyadh and Abu Dhabi that Beijing considers equally, if not more, valuable. The entire architecture of Chinese regional influence rests on not being forced to choose.

Why History Makes Beijing Cautious

There's also a lesson from the past that Beijing hasn't forgotten. Shortly before the Shah of Iran fell in 1979, China moved to strengthen ties with his government. The revolutionary leadership that replaced him resented it. Evron notes that this experience makes Beijing deeply reluctant to tie itself too closely to any regime whose survival is in question.

The economic logic reinforces this caution. Whoever governs in Tehran, Iran will still need to sell oil and gas — and China will remain its largest customer. The revenue relationship doesn't depend on the current regime's survival. There's simply no compelling incentive to take on the risks of open support.

But this restraint comes with a reputational cost that's becoming harder to ignore.

The Price of Sitting Out

Since October 7, 2023, the cascade of Middle Eastern crises has exposed the limits of Chinese political influence in the region. Despite years of diplomatic investment and infrastructure spending through the Belt and Road Initiative, Beijing has remained largely on the sidelines during every major escalation.

For a country that has positioned itself as the leading voice of the Global South and an alternative pole of global leadership, this passivity is damaging. By declining to offer any meaningful support to Iran — its own declared strategic partner — China has reinforced a perception among regional actors that it is not a reliable political player when crises actually arrive.

Evron puts it plainly: China maintains considerable economic leverage through trade, investment, and infrastructure. But economic tools have limits when missiles are flying.

China Watches Israel — and Washington — Recalibrate

One of the more counterintuitive dynamics of this conflict is what it has done to China-Israel relations. After October 7, Chinese public discourse saw an unprecedented surge of criticism of Israel and, more troublingly, antisemitic expression. Bilateral relations cooled sharply.

Yet over time, Beijing recognized something inconvenient: Israel's regional position had not collapsed — it had arguably strengthened. Chinese companies continued operating in Israel even as many Western multinationals suspended activities. Taiwan, meanwhile, seized the moment to deepen political and technological ties with Jerusalem.

The war with Iran may accelerate this pragmatic recalibration. For China, maintaining relationships with dominant regional actors is a core strategic interest — and Israel is increasingly one of them. For Israel, a war that has boosted national confidence may make it easier for policymakers to prioritize economic pragmatism over political friction.

What This Means for Taiwan — and the Broader U.S.-China Competition

The most consequential long-term implication of this conflict may have nothing to do with the Middle East at all.

China's strategic culture places enormous weight on perceptions of strength and resolve. The United States' decisive military response to Iranian provocations — carrier strike groups, sustained air operations, demonstrated logistics — sends a signal that Beijing's analysts are almost certainly processing carefully.

Evron argues this could cut in two directions. In the short term, a reinforced perception of American resolve, combined with China's current domestic economic pressures, may encourage greater caution in Beijing's strategic calculations — including on Taiwan. The combination of watching U.S. military capability up close and seeing Washington's willingness to use it may reduce the appetite for a major move during the current U.S. presidential term.

But in the longer term, the opposite dynamic takes hold. Observing this conflict in detail — American technology, doctrine, logistics, and the domestic and international reactions to U.S. military operations — gives Chinese military planners a trove of data. And the lesson they are likely to draw is not that military force is obsolete. It's that they need more of it.
