The Biden administration's national security adviser, Jake Sullivan, is in Beijing for talks with China's top foreign policy official, Wang Yi, in an effort to manage differences between the two countries. The discussions will cover various issues, including cooperation on limiting the spread of fentanyl, military contacts, Taiwan, and concerns about China's support of Russia. Both sides are expected to raise objections, with China seeking to ease pressure from the US in hopes of smoother relations with the next administration. The potential for a meeting between President Biden and China's leader, Xi Jinping, before Biden's term ends is also a topic of interest. Key flash points in the discussions include Russia's war in Ukraine, China's aggression toward Taiwan, and technology controls. The visit could lay the groundwork for a potential summit between Xi and Biden, with China cautiously preparing for the outcome of the US elections.
