President Xi Jinping has personally promised Donald Trump that Beijing is auditing and curtailing the assistance it provides to Tehran, US Ambassador David Perdue said. The commitment focuses on halting the transfer of intelligence, electronics components, and direct military equipment, which Washington characterized as unacceptable. During a state visit to Washington, Trump and Xi also discussed the war in Iran and the reopening of the Strait of Hormuz, with Trump stating he believed the two leaders would "do great" in resolving the issues.

The assurance follows reports that China sent roughly 1,300 air shipments of dual-use drone and missile components to Iran's Defense Ministry through June 2026. While Treasury Secretary Scott Bessent reported that Beijing has since reduced its aid, some Republican senators expressed dismay over Trump's friendship with Xi following allegations that Chinese aid helped Iran target US troops. Additionally, flight data for Mahan Air shows cargo runs from China to Iran rose from 4 per week in March to 39 in early September.
