Former President Trump has stated that China has agreed not to send weapons to Iran, a claim he has made in various interviews and letters exchanged with Xi Jinping. This assertion comes at a time when U.S. intelligence reports suggest that China may be preparing to provide military aid to Iran, including air defense systems. Trump has warned China of potential 50% tariffs if they continue to support the Iranian regime militarily. Despite claims of cooperation, China has denied any plans to supply arms to Iran and has threatened countermeasures against the U.S. if pressured. The geopolitical tensions are further complicated by concerns about the impact on oil supplies and the reopening of the Strait of Hormuz.
