Exploring the emerging balance of power in Northeast Asia (NEA) and Russia's role in that system, this book highlights its crucial importance to both the wider Asia-Pacific and the global international system. Replacing America's hegemony, this multipolarity is somewhat skewed, with the U.S. and China as the two strongest actors, while Russia, North and South Korea, Japan, and Taiwan are noticeably less influential in the region. The picture is further complicated by the fact that some of the regional players are not fully independent in their foreign policies. Russia and the Balance of Power in Northeast Asia, this book puts forward that NEA is likely to develop a stable multipolar system sustained by system-wide forces, namely demographic processes, nuclear deterrence, and multilateral institutions with Russia having the potential to make a significant input into the creation of a stable and relatively peaceful balance of power order in NEA.
