The running saga of China and Japan at odds is unparalleled in world history. Its long stretch of recurrent conflicts, going back to the 16th century, through two savage wars in the 19th and 20th centuries, saw a new surge in recent months, despite normal trade relations. The worst scenario had it that the two nations might go to war for their conflicting claims to the vast seabed oil resources in the East China Sea, further exacerbated by their festering territorial and other disputes. This edited book offers a rare attempt to decipher the perpetual conflict, from the Chinese, Japanese, and American perspectives. It places Sino-Japanese relations in a diachronic context but looks into the future from the present.
