US intelligence indicates that China is preparing to deliver new air defense systems to Iran within the next few weeks, according to three people familiar with recent intelligence assessments.

It would be a provocative move considering Beijing said it helped broker the fragile ceasefire agreement that paused the war between Iran and the US earlier this week. President Donald Trump is also set to visit China early next month for talks with Chinese President Xi Jinping.

The intelligence also underscores how Iran may be using the ceasefire as an opportunity to replenish certain weapons systems with the help of key foreign partners.
