Longtime FRONTLINE correspondent and director Martin Smith returns to talk about his latest documentary, China, the U.S. &the Rise of Xi Jinping.  With President Trump vowing larger tariffs in his second term, the documentary examines China’s rise to economic prominence, the life and vision of its longstanding leader, and rising tensions with the United States over issues such as trade and the future of Taiwan.  Smith sat down with FRONTLINE Editor-in-Chief and Executive Producer Raney Aronson-Rath to talk about the challenges of making the documentary — including not being able to film inside China — and why he chose to focus on the life and career of President Xi.  “He's the leader of our chief global rival, and I think a lot about him is not understood,” Smith told Aronson-Rath. “We thought it was important for people to understand who he is, where he came from, what made him into the man he is.”  You can watch China, the U.S. & the Rise of Xi Jinping, from the award-winning team of Smith, producer and director Marcela Gaviria and producer Brian Funck, on FRONTLINE’s website, FRONTLINE’s YouTube channel and the PBS App.  Want to be notified every time a new podcast episode drops?
