On Monday, Joe Biden meets with China’s leader Xi Jinping. It’s their first one-on-one virtual summit since Biden became president. Relations between the two superpowers have wide-ranging ripple effects throughout the globe, yet over the years, that relationship has been strained — even adversarial. Host Marco Werman speaks with Susan Thornton, a retired career diplomat focused on China and East Asian affairs who is now a senior fellow at Yale Law School’s Paul Tsai China Center.
