Chinese suppliers sent around 1,300 shipments of dual-use components to Iran’s defense ministry in the first half of 2026, helping sustain its weapons programs, The Wall Street Journal reported.
Iranian customs records showed one delivery arriving on June 17, when Washington and Tehran signed a 60-day truce and China promoted its peacemaking role. More than a dozen shipments followed two days later, carrying over $6 million in parts usable in drones.
The findings put Chinese support for Tehran at the center of Xi Jinping’s Washington visit this week, alongside trade, artificial-intelligence safety and Taiwan. Trump told aides that preserving relations with Xi was a priority, the Journal reported.
Records supplied by ImportGenius, covering January 2025 through June 2026, listed thousands of shipments to Iranian companies and the defense ministry, including GPS devices, motors and aircraft engine parts. Many cited Article 119, which exempts defense imports from tariffs.
Days before war began on February 28, China delivered 300 tons of chemical compounds to the ministry. Trade initially collapsed, and April’s US naval blockade restricted supplies further. Iran responded by expanding air connections.
US-sanctioned Mahan Air increased flights from Beijing, Shanghai and Guangzhou to Tehran from four weekly in early March to about 27 by late April, FlightRadar24 data showed. It operated 39 China–Iran flights in September’s first week, twice its prewar level. Several were unavailable for passenger bookings. China services continued despite announced suspensions to Oman and Turkey.
CSIS researcher Kate Koren identified Chinese companies advertising sensitive electronics used in Shahed drones. Suppliers cultivated Iranian customers through trade fairs and Persian-language marketing.
Chinese chemical supplies also helped replenish missile production damaged by Israeli attacks in 2024. After reports of those exports in 2025, US forces raided a ship carrying dual-use components from China to Iran.
In a December letter, sanctioned Chinese company Haokun Energy said it had coordinated confidential export licensing for sodium perchlorate, used in missile propellant, and created a Beijing shell company for the transaction. The Journal verified the company’s registration but could not establish whether the deal proceeded.
Washington also targeted networks seeking newer Chinese shoulder-fired missile systems for Iran, which manufactures versions based on older Chinese designs. One unsuccessful effort sought delivery through Belarus to conceal Iran’s Center for Innovation and Technology Cooperation as the recipient. Tasnim separately published footage of IRGC personnel training with portable launchers.
