In a changing security environment shaken by the United States' pivot to Asia, China's rise, growing economic interdependence, new institutional frameworks, and long-standing tensions, regional security dynamics within East Asia have changed profoundly. Non-Traditional Security in East Asia assesses how and why these and other developments have affected East Asian security regimes in the early 21st Century. This volume brings together experts in different areas of traditional and non-traditional security — ranging from arms and weapons proliferation to climate change and biosecurity — to analyze the recent evolution, current state and possible future of East Asian security dynamics which have been built on dynamics dating back to the Cold War. This volume's holistic exploration of East Asian security makes it a sophisticated introduction for students, researchers and policymakers who are interested in East Asian security and international relations.
