A recent incident in the Taiwan Strait has heightened tensions between the U.S. and China, with U.S. national security adviser Jake Sullivan expecting a meeting between President Joe Biden and Chinese leader Xi Jinping. Defense Secretary Lloyd Austin requested a bilateral meeting with his Chinese counterpart, but was denied. Sullivan and Chinese foreign minister Wang Yi did meet to discuss strategic issues, but Austin believes this is no substitute for a substantive engagement. The two sides remain at odds over a number of issues, with the future of the relationship uncertain.
