• Chinese President Xi Jinping called for the U.S. and Iran to resume negotiations quickly, according to Xinhua, as Beijing pushes to reopen the Strait of Hormuz.
  • Foreign Minister Wang Yi told his Iranian counterpart that Tehran and Washington should return to their June interim arrangement—the Islamabad Memorandum of Understanding—and hold substantive talks.
  • The diplomacy comes as Beijing seeks to protect its energy imports and supply chains while using its access to Tehran as leverage in broader U.S.–China talks.

Diplomatic Push Intensifies

Chinese President Xi Jinping has urged the United States and Iran to return to the negotiating table "as soon as possible," according to state-run Xinhua, in a fresh diplomatic intervention aimed at preventing the conflict from deepening and restoring shipping through the Strait of Hormuz.

The appeal came as Foreign Minister Wang Yi met with Iranian Foreign Minister Abbas Araghchi in Beijing on September 16, according to people familiar with the matter. Wang urged Tehran and Washington to exercise restraint, revive their June interim arrangement known as the Islamabad Memorandum of Understanding, rebuild their negotiating framework and hold substantive talks on unresolved issues.

Beijing's immediate practical priority is reopening the Strait of Hormuz and protecting international sea lanes, the people said. Chinese officials have argued that closure or insecurity in the waterway threatens energy transport, manufacturing supply chains and global economic stability.

There is no confirmed breakthrough in U.S.–Iran diplomacy at this point. China has called for dialogue and said it is ready to play a constructive role, but it has not publicly announced a formal mediation process or committed to pressuring Iran to accept U.S. terms.

Strategic Leverage

The Iran issue has gained prominence during Xi's Washington visit and talks with President Donald Trump, according to Reuters. Iran, along with trade, technology, Taiwan and artificial intelligence, is a principal item on the U.S.–China agenda. Washington wants to discuss China's financial links to Tehran, while Beijing is using its diplomatic access to Iran as an important element of its broader dealings with Washington.

The two governments have agreed to extend their trade truce through January 10, reducing one immediate bilateral economic risk even as disputes persist over chips, rare earths, tariffs and Iran. A de-escalation would likely reduce energy-risk premiums and improve business confidence. Conversely, a failure of diplomacy—especially if the conflict expands into Yemen or the Red Sea—could compound disruptions across oil, shipping and trade routes.

The Strait of Hormuz is a major conduit for oil and gas shipments, so prolonged insecurity can raise freight, insurance and energy costs, add to inflation pressure and disrupt industrial supply chains—particularly across Asia, where China is a large energy importer. Beijing's public demand for reopening the waterway reflects that exposure.

China is identified as Iran's principal oil buyer, meaning U.S. efforts to isolate Iranian financial activity directly intersect with Chinese commercial and strategic interests. Washington is seeking to constrain China's financial ties with Iran and limit Tehran's ability to operate in Western-linked financial systems. China's call for negotiations does not imply that it accepts the U.S. sanctions strategy.

Regional Risks

China has warned against escalation into Yemen and the Red Sea, reflecting concern that a Persian Gulf conflict could broaden into a multi-front maritime-security crisis. The diplomatic framing emphasizes restraint, negotiation, respect for sovereignty and dialogue between Iran and Gulf states.

Tehran gains an important diplomatic channel through Beijing but may also face pressure to show openness to negotiations. U.S. policymakers must balance military and economic pressure on Iran with the need to avoid prolonged energy-price shocks and regional escalation, a politically sensitive issue domestically, according to Reuters.

A limited practical objective—safer maritime navigation or steps toward reopening Hormuz—may be more achievable than an immediate settlement of the underlying U.S.–Iran disputes. The most plausible near-term outcome is continued diplomatic messaging rather than a comprehensive agreement, according to people familiar with the matter.

If China helps restore a durable negotiating channel, it could strengthen Beijing's diplomatic standing in the Middle East and reduce risks to global energy markets. If negotiations fail, the likely consequences include a more entrenched U.S.–Iran confrontation, sustained pressure on energy and shipping markets, wider regional instability and sharper U.S.–China friction over sanctions enforcement.
