Why China is keeping its distance as Iran faces escalating attacks has become one of the defining questions of the latest crisis in the Middle East. Despite being Tehran’s most important economic partner and the primary buyer of its oil exports, Beijing has limited its response to diplomatic criticism as the United States and Israel intensify military pressure on Iran.
China purchases an estimated 90% of Iran’s oil exports, providing a crucial financial lifeline to a country battered by years of international sanctions. Yet beyond condemning the strikes as destabilizing and calling for restraint, Beijing has shown little appetite to offer political, military, or security backing to Tehran.
The reasons for that restraint run deeper than a simple reluctance to be drawn into another regional conflict. The China–Iran relationship, while often portrayed as a strategic partnership, is in reality far more uneven, pragmatic, and limited than many assume.
Ties with Tehran matter to Beijing, but they rank well below China’s most critical strategic relationships, particularly with Russia. While Iran provides discounted energy and symbolic support for China’s efforts to counter US influence, the relationship lacks the depth, trust, and mutual dependence that characterize Beijing’s bond with Moscow.
China’s engagement with Iran is driven largely by economic convenience rather than ideological alignment or shared security goals. For Beijing, Iran is a useful partner, but not an indispensable one.
That reality helps explain why China has been unwilling to go beyond rhetoric as Iran comes under sustained military pressure.
Why China is keeping its distance as Iran faces escalating attacks is also tied to Beijing’s broader Middle East strategy, which is built on careful balance rather than firm alliances.
China has spent years cultivating strong ties not only with Iran but also with its regional rivals, including Saudi Arabia and the United Arab Emirates. Those relationships are central to China’s energy security, investment ambitions, and long-term influence in the Gulf.
Providing overt support to Iran during a conflict that directly threatens Gulf states would risk undermining those carefully managed partnerships.
“She Gangzheng, a professor of international relations at Tsinghua University, has described military backing for Iran as simply ‘not the way China does things in the region,’” reflecting a longstanding preference for economic engagement and diplomatic positioning over security commitments.
China is unquestionably Iran’s dominant trade partner, but the imbalance between the two economies is stark.
China absorbs roughly a third of Iran’s total trade. Iran, by contrast, accounts for less than 1% of commerce for the world’s second-largest economy, according to data from the Center for Strategic and International Studies.
That asymmetry limits Iran’s leverage. While Tehran depends heavily on access to Chinese markets and financial channels, Beijing can afford to absorb disruptions or seek alternatives if necessary.
Iran’s discounted crude makes up about 13% of China’s seaborne oil imports. That contribution helps Beijing diversify its energy supply alongside sources such as Russia and Saudi Arabia, but it is ultimately replaceable.
Despite repeated headlines about deepening economic cooperation, Chinese investment in Iran has consistently fallen short of expectations.
In 2021, Chinese Foreign Minister Wang Yi signed a 25-year strategic cooperation agreement during a visit to Tehran. The deal was widely reported as envisioning up to $400 billion in Chinese investment across energy, infrastructure, and technology.
In practice, confirmed investment since then has totaled only about $2 billion to $3 billion, according to estimates by Alicia Garcia Herrero, chief Asia Pacific economist at Natixis. That figure pales in comparison with China’s commitments in Saudi Arabia or the UAE.
Official Chinese data show foreign direct investment stock in Iran stood at $4.5 billion by the end of 2024, compared with $9.5 billion in the UAE. Tracking by the American Enterprise Institute puts cumulative Chinese investment in Iran at $4.7 billion, concentrated largely in energy and metals.
By contrast, Chinese investment in Saudi Arabia has reached more than $15 billion, spanning sectors from technology to entertainment.
Iranian officials have not concealed their disappointment.
In 2023, then-president Ebrahim Raisi publicly acknowledged a “serious regression” in bilateral ties, saying economic cooperation had failed to meet expectations. Around the same time, Iranian trade officials said Russia had overtaken China as Iran’s largest foreign investor.
Those comments underscored a growing realization in Tehran that Beijing’s support comes with limits — and that China is unwilling to jeopardize its broader global interests for Iran’s sake.
“Chinese companies have a very limited footprint in Iran relative to other countries in the region,” said Esfandyar Batmanghelidj, head of the London-based Bourse & Bazaar Foundation. “Major firms have steered clear because of secondary sanctions risks.”
China officially stopped selling weapons to Iran in 2005, after the International Atomic Energy Agency ruled that Tehran was not complying with the Nuclear Non-Proliferation Treaty. That finding led the UN Security Council, including China, to impose a de facto embargo on nuclear-related exports.
Before then, China had supplied missiles, aircraft, and artillery, according to the Stockholm International Peace Research Institute. Since the embargo, however, military cooperation has been sharply curtailed.
Reports have occasionally surfaced about Chinese air-defense systems or discussions over missile technology, but neither Beijing nor Tehran has confirmed such transfers. No Chinese-made weapons have been identified on the battlefield in the current conflict.
More plausible is the provision of so-called dual-use goods — civilian items that can also have military applications. These supplies allow China to maintain plausible deniability while staying within the gray zones of international enforcement.
Over the past eight years, more than 100 Chinese and Hong Kong entities have been added to a US Entity List for helping Iran evade export controls, according to a report by the US-China Economic and Security Review Commission.
Still, this level of support remains far below what China has provided to Russia, including drones and dual-use equipment used in the war in Ukraine.
Diplomacy over defense
Why China is keeping its distance as Iran faces escalating attacks ultimately reflects a strategic choice to prioritize diplomacy over defense commitments.
Beijing has consistently avoided offering security guarantees of the kind the United States extends to its allies. Instead, it relies on trade, investment, and mediation to project influence.
That approach was evident in China’s role in facilitating a 2023 rapprochement between Iran and Saudi Arabia. While Beijing highlighted the agreement as proof of its growing diplomatic clout, some Western diplomats questioned how central China’s role truly was.
Nonetheless, the episode bolstered China’s image as a stabilizing force — a reputation Beijing is keen to preserve as it courts countries in the Global South uneasy with Washington’s readiness to use military force.
The current crisis also coincides with sensitive diplomacy between Beijing and Washington.
With a summit between Xi Jinping and Donald Trump expected in the coming weeks, China has little incentive to escalate tensions by visibly backing Iran against US and Israeli strikes. Positioning itself as a voice of restraint allows Beijing to contrast its approach with what it portrays as American unilateralism.
That calculation helps explain China’s emphasis on international law, sovereignty, and de-escalation — without committing itself to Iran’s defense.
China’s caution is not new. When Xi Jinping visited Saudi Arabia in 2022, he did not stop in Iran, a departure from his 2016 Middle East tour. The visit drew criticism from Iranian lawmakers after Xi issued a joint statement with Riyadh that referenced Iran’s “destabilizing regional activities.”
The episode highlighted the diplomatic tightrope China continues to walk in the region.
If past behavior is any guide, Beijing will maintain its measured stance, engaging pragmatically with whoever holds power in Tehran next while avoiding steps that could drag it deeper into a volatile conflict.
Why China is keeping its distance as Iran faces escalating attacks, then, is less about abandoning a partner than about protecting its own interests — and preserving room to maneuver in a region where alliances remain fluid and risks are rising.
