This book is about Japan-China power politics in the military, economic and propaganda domains. The post-2012 standoff over the disputed Senkaku/Diaoyu Islands has unveiled the antagonistic quality to Sino-Japanese relations, with an important addition: a massive information war that has cemented the two states’ rivalry. Under the Xi and Abe administrations, China and Japan insisted on their moral position as benign and peaceful powers, and portrayed the neighbor as an aggressive revisionist. By highlighting great power rivalry, this study makes a theoretical contribution in favor of the power politics behind Sino-Japanese identities. The work is multidisciplinary in spirit and aims to speak both to academics and to general readers who might be curious of understanding this fascinating if worrisome facet of Sino-Japanese relations. In turn, the assessment of the diplomatic, economic and identity clash between the world’s second and third wealthiest states provides a window in understanding the international politics of the Asia-Pacific in the early 21st Century. This book is an invaluable resource for scholars, Area Studies and Political Science students and policymakers alike.
