This book explains the increasingly turbulent Sino-Japanese relations since the 2000s by innovatively investigating the formation mechanism of mutual misperception deeply rooted in China-Japan-U.S. trilateral structural dynamics. The political and security relationship has been increasingly deteriorating against the high interdependency between the world´s second and third largest economies. More ironically, both sides have also shown the intent and made efforts to improve bilateral ties. The author systematically conducts a focused comparison of the evolution of the Sino-Japanese mutual perceptions and policies toward one another during the past decade and a half. Empirically, Yun Zhang closely examines five case studies that provide insights to IR students and scholars and policy makers on how misperception and mistrust have formed, replicated, and intensified.
