While Washington seeks to prevent Beijing from providing Tehran with military, technological or intelligence assistance, China is attempting to preserve its strategic partnership with Iran without becoming directly entangled in a confrontation with the US.
The September 24, 2026, meeting between President Donald Trump and Chinese President Xi Jinping took place against an increasingly complicated background. The US President greeted the Chinese President in a manner befitting the status of a rising superpower, which acknowledges a multi-polar world.
Iran was among the major geopolitical issues surrounding the summit, alongside trade, technology, Taiwan and broader strategic competition.
However, it does not appear that the meeting produced a comprehensive agreement resolving the Iran conflict.
Instead, the summit demonstrated the continuing effort by Washington and Beijing to manage their broader rivalry while addressing areas in which their interests overlap.
For Washington, one of those areas is preventing Iran from acquiring a nuclear weapon and limiting the flow of military-related technology to Tehran.
For Beijing, the priority is maintaining regional stability, protecting energy supplies and preserving its economic relationship with Iran without triggering a direct confrontation with the United States.
At the center of this increasingly complex equation are three interconnected issues: Iran’s access to Chinese economic and technological networks, the security of the Strait of Hormuz, and the future of the Iranian nuclear program.
US officials have repeatedly warned Beijing that any assistance to Iran—whether involving military equipment, spare parts, intelligence or dual-use technology—would be unacceptable to Washington. In remarks reported by CNBC, US Ambassador to China David Perdue said Washington had made this position clear to Beijing, emphasizing that the warning applied to both direct and indirect assistance.
The concern comes amid continuing allegations that Chinese companies have supplied Iran with technologies and components that can have military applications.
China and Iran: A Strategic Partnership with Limits
China has become Iran’s most important economic partner, particularly because of its role as the principal buyer of Iranian crude.
According to the U.S.-China Economic and Security Review Commission, China purchases more than 90 percent of Iran’s exported oil. In 2025, Chinese purchases were estimated at roughly 1.4 million barrels per day.
For Tehran, this relationship is critical. Chinese purchases provide Iran with a major source of revenue despite American sanctions, while Chinese companies remain an important source of machinery, industrial equipment, electronics and other manufactured goods.
China also maintains substantial economic relationships with Saudi Arabia and the United Arab Emirates, whose combined trade with Beijing is significantly larger than China’s trade with Iran. Beijing therefore has strong economic incentives to prevent the conflict from disrupting the wider Middle Eastern economy.
This explains China’s cautious position: it can oppose Washington’s maximum-pressure strategy toward Tehran while simultaneously seeking negotiations that prevent the conflict from expanding.
The $41.2 Billion Relationship
The scale of China’s economic relationship with Iran underscores why Washington has difficulty isolating Tehran completely.
The U.S.-China Economic and Security Review Commission estimates that bilateral trade between China and Iran reached approximately $41.2 billion in 2025 when Iranian oil imports not fully reflected in official statistics are taken into account.
Iran primarily exports oil, condensates, petrochemicals and other industrial products to China. Chinese exports to Iran include machinery, vehicles, industrial equipment, electronics and other manufactured goods.
China receives discounted Iranian crude, while Iran gains an essential outlet for its oil despite American sanctions.
This arrangement has created a degree of economic interdependence that cannot easily be dismantled through conventional sanctions alone.
The Strait of Hormuz: China’s Strategic Vulnerability
The Strait of Hormuz has become the critical pressure point of the conflict. Prolonged disruption to the waterway threatens global energy markets because of the enormous volume of oil and gas transported through the region.
China has a direct interest in preventing such disruption. As the world’s largest importer of crude oil, Beijing cannot afford prolonged uncertainty surrounding Gulf energy supplies.
Recent reporting has shown how sharply maritime traffic through the strait has been affected by the conflict, increasing pressure on energy markets, shipping companies and insurers.
China wants Iran to remain economically viable and does not want to surrender its strategic relationship with Tehran. At the same time, it has no interest in an extended conflict that could destabilize global energy markets and damage China’s own economy.
A Three-Way Strategic Balance
The China-Iran relationship should therefore not be interpreted simply as an alliance in which Beijing automatically follows Tehran.
China has significant interests in Iran, but it also has enormous economic interests elsewhere in the Middle East and in its relationship with the United States.
Washington wants China to use its leverage against Tehran, while Tehran wants Beijing to remain an economic and diplomatic lifeline.
Beijing wants to preserve its strategic relationship with Iran without paying the price of direct confrontation with Washington.
The future of the conflict may ultimately depend not on whether China chooses Iran or the United States, but on how Beijing manages the space between them.
The Strait of Hormuz, Iranian oil exports, sanctions, satellite intelligence, dual-use technology and the nuclear issue have become interconnected elements of the same strategic contest.
For Iran, China remains a critical economic partner. For Washington, China represents both a potential obstacle to sanctions and a potential source of leverage over Tehran. For Beijing, Iran is simultaneously a strategic partner, an energy supplier and a potential source of geopolitical risk.
The next phase of the conflict will therefore be shaped not only on the battlefield or at the negotiating table in Washington and Tehran, but also in Beijing.
The decisive question is whether China can preserve its relationship with Iran while helping prevent the conflict from expanding into a wider regional and global confrontation.
The answer will have consequences far beyond the three countries involved. It could determine the future of the Strait of Hormuz, the stability of global energy markets, the direction of U.S.-China competition and the balance of power across the Middle East.
