China-Iran: The Limits of Beijing’s Partnership With Tehran

• China will likely view Iran’s survival against US and Israeli pressure as strategically useful, but not as a reason to abandon its balancing strategy in the Gulf. Beijing is unlikely to treat Iran as a formal ally or assume meaningful security obligations on Tehran’s behalf.

• China’s long-term economic and energy interests remain anchored in the Gulf states, particularly Saudi Arabia, the UAE, Qatar, and other Gulf Cooperation Council (GCC) economies that provide scale, stability, investment opportunities, and diversified energy access.

• Beijing will likely seek to deepen ties with Iran while avoiding a regional conflict that threatens Gulf energy flows, disrupts the Strait of Hormuz, or damages the global economy.  

Iran’s strategic value has almost certainly improved in Beijing following the latest phase of the US-Iran-Israel conflict. The US and Israel attempted to use military pressure to weaken Iran, alter its behavior, and reshape the regional balance. That has not materialized. Iran’s government remains in place, Tehran continues to hold leverage over the Strait of Hormuz, and Washington is now attempting to negotiate a way out.  

Whether China sees this as a “strategic defeat” for the US and Israel is difficult to determine, but it will likely view Iran’s resilience as a strategic lesson. The question is how much risk Beijing is willing to assume on Tehran’s behalf. On that question, Beijing’s posture is likely to remain cautious. While Iran is strategically valuable to China because it provides leverage, the Gulf states offer the economic scale and stability that underpin Beijing’s Middle East strategy. 

Energy explains much of this imbalance. China is the world’s largest energy importer and requires stable access to Gulf oil and gas. Iran remains an important supplier, particularly because it sells discounted crude, often through opaque channels designed to evade sanctions. But China’s core energy relationship remains with the Gulf Arab states. Saudi Arabia, Iraq, Oman, the UAE, Kuwait, and Qatar together accounted for roughly 44 percent of China’s official crude oil imports in 2024. Qatar is also increasingly important as a liquefied natural gas (LNG) partner.

For Beijing, Iran is a discounted and high-risk supplier; the Gulf is the indispensable energy core. This distinction matters because while China may value Iran politically, it cannot afford a prolonged disruption to Gulf energy flows. 

A similar imbalance is evident in investment ties. China’s relationship with Iran attracts significant attention because of its strategic symbolism, but sanctions have sharply limited the scale of transparent and commercially viable Chinese investment there. Chinese firms remain cautious about secondary sanctions, financing risk, and reputational exposure.  

By contrast, the Gulf provides China with bankable projects across energy, refining, petrochemicals, ports, logistics, digital infrastructure, manufacturing, and clean-energy transition sectors. Iran cannot match that economic scale under the current sanctions regime. 

Military cooperation tells a more complicated story. China and Iran have visible defense ties, including naval exercises involving both countries and Russia. There are also persistent concerns about Chinese entities helping Iran acquire components or dual-use materials relevant to its missile and drone programs. But China’s overt military relationship with Iran remains restrained. Beijing has not given Tehran a hard security guarantee, and it is unlikely to fight Iran’s war.

China’s military relationship with the Gulf is also expanding, though it is still well short of the US’s role. The UAE is the most notable example, particularly through repeated China-UAE Falcon Shield air force exercises. Even so, the Gulf’s defense architecture will remain anchored in the US and Europe for the foreseeable future. China is becoming more relevant, but it is not replacing the US security umbrella, even as flawed as Washington may be perceived now by several Gulf states who endured Iranian attacks. 

China’s public position after the strikes has been predictable: condemn US-Israeli military action, call for de-escalation, emphasize sovereignty, oppose escalation around the Strait of Hormuz, and present itself as a responsible diplomatic actor. China wants the political benefits of opposing the US, but it does not want the economic costs of a wider war.

There is also a Taiwan dimension. Xi Jinping’s long-term objective remains reunification with Taiwan, whether through political pressure, coercion, or force. A prolonged US military and political entanglement in the Middle East may benefit China by draining US attention, munitions, and credibility.  At the same time, China understands that a major energy shock, a closed Strait of Hormuz, or a broader regional war would directly harm its own economy. Beijing wants the US weakened, distracted, and discredited, but it does not want a wider conflict that breaks the global economy on which China itself depends.  

China-Iran ties will likely grow if the conflict ends without a durable agreement. Tehran will place more value on Beijing as its most important economic lifeline and a diplomatic counterweight to Washington. If reports are confirmed that Mohammad Bagher Ghalibaf is being positioned to play a larger diplomatic role with Beijing, it would suggest that Tehran is attempting to elevate the bilateral relationship.

Iran will likely seek more Chinese support in oil sales, sanctions evasion, financial channels, dual-use technology, and diplomatic protection. Any deeper intelligence or military cooperation would likely remain opaque and difficult to verify. For its part, China will likely continue to hedge. Beijing will not want Iran to dominate the Strait of Hormuz or create a lasting disruption to Gulf energy flows.  

For the Gulf states, China will remain economically indispensable but strategically ambiguous. Beijing will deepen trade and investment with Saudi Arabia, the UAE, Qatar, and others, but it will also keep Iran close enough to preserve leverage against the US. The Gulf will continue to court China, but it will also remain uneasy about Beijing’s ties to Tehran.

Iran may have become more valuable to China because of the war, but the Gulf remains more important, at least in the short to medium term. Beijing’s likely strategy is not to choose between Iran and the Gulf – it is to use Iran as a strategic hedge while preserving the Gulf as the foundation of China’s Middle East policy.
