U.S. President Joe Biden and China’s Xi Jinping have emerged from their first face-to-face meeting in a year vowing to stabilize their fraught relationship and showcasing modest agreements to combat illegal fentanyl and re-establish military communications. There were still deep differences on economic competition and global security threats. But Biden said they agreed to “pick up the phone” and talk if urgent issues arise. Biden said “that's important progress." Xi signaled later Wednesday that China would send the U.S. new pandas after recalling three from the National Zoo in Washington last week.
