In this episode of the ChinaPower Podcast, Dr. Sheena Chestnut Greitens joins us to discuss one of President Xi Jinping’s signature priorities: China’s national security. She delves into Xi's “Comprehensive National Security concept,” emphasizing its broad scope with over 20 different components, covering everything from border security to food security. Dr. Greitens discusses Xi Jinping’s preventive rather than reactive approach to security threats, in an attempt to treat what the CCP views as root causes to security issues rather than just the symptoms. Finally, Dr. Greitens explains how China’s views of national security influences how it exerts control at home and uses force abroad.  Dr. Sheena Chestnut Greitens is Associate Professor at the LBJ School of Public Affairs at the University of Texas at Austin, where she directs UT’s Asia Policy Program. Her research focuses on security, authoritarian politics, foreign policy, and East Asia. Currently, Dr. Greitens is on leave to serve as a Visiting Associate Professor of Research in Indo-Pacific Security at the U.S. Army War College’s Strategic Studies Institute. She is also concurrently a Nonresident Scholar with the Asia Program at the Carnegie Endowment for International Peace.
