Trump-Xi summit: China's help in Iran may require US concessions

The Geopolitical Chess Game of the Trump-Xi Summit

When President Donald Trump meets with his counterpart, Xi Jinping, a new item will be added to the long list of issues of mutual interest and potential disagreement between the United States and China: the war in Iran. US officials have suggested that China should play a greater role in pushing Iran to reopen the Strait of Hormuz, but analysts say Beijing will require concessions from the US, likely over Taiwan, if it were to aid in resolving the crisis.

Iran as a New Front in US-China Relations

Although the Iran issue is not really the central issue for either party in this summit, according to Christopher Heurlin, an associate professor of government and Asian studies at Bowdoin College, it represents a new dimension in the complex relationship between Washington and Beijing. China is a major importer of Iranian and Middle East oil, so its economy could come under strain from the disruption caused by Tehran's Hormuz blockade and the US naval siege on Iran.

The Strategic Calculus Behind China's Involvement

While Beijing has amassed oil reserves that have helped it weather global energy shortfalls, such resources are finite, so China has an interest in opening the strait. At the same time, if Washington – Beijing's chief strategic competitor – is weakened globally from the Iran conflict, which is increasingly looking like an unwinnable war for many observers, China could gain geopolitical advantage. Inderjeet Parmar, professor of international relations at City St George's, University of London, noted that Trump heads to China "chastened" by the shortcomings of the Iran war.

The Taiwan Factor in Iran Negotiations

A major priority for Beijing is Taiwan, the self-governing island that China claims as its own. If Xi were to help Trump in his push to reopen Hormuz, the assistance would not come for free, analysts say. China may demand opposition to Taiwanese independence in exchange for putting pressure on Iran to reopen Hormuz. Trump is yet to sign off on the latest arms package to Taiwan – worth $14bn – which has been approved by Congress, and Chinese officials are expected to press him on this issue during the summit.

Contrasting Approaches to Middle East Crisis

While China and the US both want Hormuz to open, their preferred approaches to achieve this goal don't align. China has been calling for restraint from all sides, while Trump has been threatening Iran with enormous military attacks almost daily. In April, Xi proposed a "four-point plan to safeguard and promote Middle East peace and stability" that reflected a preference for multilateralism and diplomacy in contrast with Trump's reliance on military power to advance his goals in the region.

The Future of US-China Relations Beyond the Summit

Although the United States seeks to continue to cooperate with China, the relationship between the two countries has soured in recent years over several points of tension: trade practices, sanctions, Beijing's claims to the South China Sea, the COVID-19 pandemic, and the status of Taiwan. Since returning to the White House in January 2025, Trump and his administration have put less emphasis on the great power competition, with Trump's most recent National Security Strategy aiming to shift its focus to the Western Hemisphere. However, tariffs and trade remain a major irritant in the relationship, and Iran and Taiwan could exacerbate tensions in the coming months.
