China–Iran trade relations
China–Iran trade relations have expanded in recent years, driven by economic, energy, and strategic cooperation. As Iran’s largest trading partner, China conducts billions of dollars in bilateral trade annually, primarily through Iranian oil exports and Chinese manufactured goods. Despite international sanctions, China has sustained economic engagement with Iran, often employing alternative financial mechanisms to bypass restrictions. Chinese investments span multiple sectors, including infrastructure, transportation, energy, and defense, and also Iran's nuclear program.
