How China’s Weapons Transfers to Iran Have Evolved Over Decades

Key Points:

• U.S. intelligence agencies are investigating claims that China may have recently shipped shoulder-fired missiles to Iran, which would mark a significant shift in Beijing's military support strategy.
• President Trump has threatened to impose an additional 50% tariff on Chinese goods if the missile shipment claims are verified, while China denies the allegations and warns of retaliation.
• Historically, China’s arms sales to Iran peaked in the 1980s but have largely ceased in the past decade due to UN embargoes and U.S. sanctions, with recent support limited to dual-use components for civilian and military technologies.
• China has strong economic interests in Iran, importing about one-third of its crude oil from the Persian Gulf region, influencing its cautious military engagement.
• The evolution of China’s military relationship with Iran reflects a shift from direct arms sales during the 1980s Iran-Iraq War to more indirect assistance aligned with international sanctions and geopolitical considerations.
