U.S. Trade Representative Jamieson Greer stated that the United States is seeking a stable relationship with China, but warned that if Beijing becomes involved with Iran in a way that goes against American interests, that would complicate matters between the two countries. Greer said he expects a positive meeting next month between President Trump and Chinese President Xi Jinping, but acknowledged that not every challenge with China has been resolved.

Why it matters

The U.S. and China have been engaged in an ongoing trade dispute, and the potential for further tensions over Iran policy could exacerbate the already strained relationship between the world's two largest economies. Greer's comments suggest the Biden administration is still grappling with how to manage the complex geopolitical dynamics between the U.S., China, and Iran.
