This edited book reflects the "yin-yang" of East Asia — the analogy of co-existing "hot and cold" trends in that region. To concentrate only on geopolitical competition and regional "hot spots" will exaggerate, if not misrepresent East Asia as a Hobbesian world. Nevertheless, geopolitical competition cannot be ignored because a failure of the balance of power and deterrence between China and the United States (and its allies) will destabilise the region. There are four "vectors" in the geopolitics of East Asia: China rising, the United States "rebalancing" to this region, Japan "normalising" as a nation-state and ASEAN emerging as a regional community. The interplay of these four "vectors" will set the trajectory of geopolitics in East Asia. Another focus of this volume is on the politics of identity.
