Will China Defend Iran? Beijing’s Middle East Calculus

As the United States undertakes another military venture in the Middle East, many in Washington are asking what an attack on Iran means for China. It has become increasingly common in U.S. political discourse to describe China and Iran, alongside Russia and North Korea, as an axis of “upheaval,” “chaos,” or “autocracy,” supposedly united in their efforts to undermine U.S. power and reshape the international order. Despite pushback that this is a mischaracterization of China’s foreign policy, certain hawkish circles are casting the war as not just an attack on Iran but also a strategic move against China, with Beijing’s decision not to intervene cited as evidence of the limits of its influence.

Such arguments—that China stands to lose a crucial anti-American partner or that that its restraint signals weakness—rest on a fundamental misunderstanding of China’s interests in the Middle East and its strategy for pursuing them. China’s engagement there in recent years has been largely pragmatic and belies the notion of an anti-American alliance with the Islamic Republic. Beijing’s priority is not the survival of the current Iranian regime but the preservation of its own economic, energy, and technological interests in whatever regional security order emerges after the conflict.

Beijing’s priority is not the survival of the current Iranian regime but the preservation of its own economic, energy, and technological interests in whatever regional security order emerges after the conflict.

China and Iran have maintained a mutually beneficial partnership for years. China covertly purchases Iranian oil at discounted rates—thanks, ironically, to U.S. sanctions on Iran and incomplete enforcement of them. China is Iran’s largest trading partner, a major investor in the country, and has provided Iran with diplomatic support at the United Nations Security Council. Beijing has also provided limited security assistance to Tehran, including reportedly selling chemical inputs for ballistic missile production as well as dual-use technologies, and the countries’ militaries have conducted joint exercises.

Still, the strategic significance of this partnership should not be overstated. Iran needs China, but China does not need Iran. In 2025, China reportedly accounted for roughly 80 percent of Iran’s oil exports, but this was only about 13 percent of China’s total seaborne oil imports.

Avoiding dependence on any single supplier or region is a cornerstone of Chinese foreign policy. Even as the cascade of conflicts following Hamas’s Oct. 7, 2023, attacks on Israel—from wars in Gaza and Lebanon to the fall of Bashar al-Assad in Syria—severely diminished Iran’s power and network of proxies in the region, China limited its response to continued economic engagement and calibrated diplomatic posturing. Nor did it intervene when Iran was directly attacked by Israel in October 2024 and again by Israel and the United States in June 2025.

Though the latest round of U.S. and Israeli strikes on Iran cuts against China’s interests, it is unlikely to drive Beijing to intervene militarily or provide Tehran with decisive support.

Beijing could tolerate regime change in Tehran, or a significant transformation of the Islamic Republic, should the U.S.- and Israeli-led campaign fall short of toppling it.

One reason for this is that China’s partnership with Iran is rooted in access to resources and markets, not in Tehran’s supposed anti-American ideology or support for proxy attacks against U.S. and allied targets. Although Beijing views the United States as its principal strategic competitor and benefits from global discontent with U.S. protectionism and militarism, its regional relationships are not organized around these principles.

Indeed, China’s deeper and more strategically valuable relationships with Saudi Arabia and the United Arab Emirates—both of which are U.S. security partners and rivals of Iran—undercut the notion that Beijing’s Middle East policy is aimed at supporting a global “axis of upheaval.”

Further, China’s greater interests in the conflict extend well beyond Iran. Roughly 55 percent to 60 percent of China’s oil imports come from the Middle East, including Saudi Arabia, the United Arab Emirates, Kuwait, and Iraq—and the vast majority of those shipments flow through the Strait of Hormuz. The region is also central to China’s trade with Europe; before Houthi attacks starting in late 2023 disrupted Red Sea shipping, an estimated 60 percent of Chinese trade with Europe passed through Bab el-Mandeb. Beijing has invested heavily in regional ports, railways, and digital infrastructure and is keen to receive greater foreign direct investment from the wealthy Gulf states.

China’s priority now is therefore not ensuring the survival of an Iranian regime that is dependent on China but preserving its own interests in the wider region. This is backed up by China’s largely passive and pragmatic record of engagement in the Middle East over the past two and a half years, comprised of three main elements.

First, China has consistently demonstrated an aversion to direct military action or significant military risk. When instability erupts, Beijing typically evacuates Chinese nationals, such as the much-trumpeted operation in Libya in 2011, and then seeks to shield its commercial interests through supply-chain diversification and bilateral negotiations, even as other actors continue fighting.

Second, China has sought to capitalize diplomatically by positioning itself as an alternative to an increasingly unpopular and destabilizing United States—and, to a lesser extent, Israel. After Israel’s assault on Gaza began in late 2023, Beijing repeatedly condemned Israeli actions and refrained for months from condemning Hamas’s initial attack, despite growing economic and technological ties between the countries over the preceding decade. Beijing supported cease-fire resolutions at the U.N. Security Council, offered to host talks on the Israeli-Palestinian conflict, and later attempted to broker reconciliation between Hamas and its Palestinian rival Fatah. It has likewise condemned the current war, framing it as yet another example of the United States’ hegemonism and destruction.

Third, China has demonstrated a willingness to engage governments across the ideological spectrum, including those that have come to power through revolutionary violence, suggesting that it would attempt to reestablish ties with Tehran even in the event of U.S.-imposed regime change.

Syria provides an instructive example. Beijing was one of the Assad regime’s few international backers; although the economic and security partnership was limited, it provided important diplomatic support and counterterrorism cooperation and grew to a strategic partnership agreement in October 2023. When Assad’s regime collapsed in late 2024 and the Hayat Tahrir al-Sham (HTS) militant group took control, China found itself in an awkward position—particularly given the presence of thousands of Uyghur fighters within the HTS coalition and the elevation of some to senior posts in the transitional government.

Nonetheless, rather than isolate or topple the new government, Beijing has attempted to leverage its economic power to secure assurances that Syria will not support Uyghur separatism or interfere in what China considers “internal affairs.” A successor regime in Iran is unlikely to pose as significant a threat to China’s core red-line interests as the HTS coalition, suggesting that similar pragmatism would prevail if the Islamic Republic falls.

Egypt offers another example. After the toppling of the Hosni Mubarak regime in 2011, with which China had a strong relationship, Beijing expressed its respect for the “choice of the Egyptian people” and welcomed the Islamist Mohamed Morsi in Beijing soon after his presidential election in 2012. When Morsi was overthrown in a coup in June 2013, Beijing again quickly moved to restore ties with President Abdel Fattah al-Sisi’s new regime.

From Beijing’s perspective, the gravest risk in Iran is not regime change—even if it produces a relatively pro-U.S. government. That would be inconvenient and potentially costly, but not catastrophic. The outcome that would genuinely alarm Beijing and potentially drive it to intervene in the Middle East and retaliate against the United States would be a concerted effort to leverage a hypothetical victory to push China from the region altogether.

Early signs of such pressure are already visible in Syria, where Washington has urged authorities to stop using Chinese telecommunications technology. The rhetoric of expulsion is also getting louder in the Western Hemisphere; since its attack on Venezuela earlier this year, the United States has pushed for renewed scrutiny of Chinese involvement in the Panama Canal and for Peru to reduce its partnership with China, including through the Chinese-built Chancay Port.

This is not to say that Washington plans to pursue such an approach, or that it could if it wanted to do so. The Trump administration has insisted that the current conflict is not about China. But if this exclusionary policy were extended systematically to the Middle East region—to its oil supplies, growing artificial intelligence industry, or trade thoroughfares such as the Strait of Hormuz and the Red Sea—it could trigger the kind of Chinese retaliation that so far has been absent. This would still likely not come in the form of direct military engagement, which China has consistently avoided, but rather export controls on rare earths and other industries such as pharmaceuticals, where it controls a U.S. choke point.

But as long as Beijing can preserve its core economic and strategic interests in a post-Islamic Republic regional order, it is unlikely to assume the substantial risks required to directly intervene in shaping it.
