The present treatise, his 22nd book, is a rare in-depth analysis of the Sino-Japanese island dispute from the perspectives of both history and the international law of territorial acquisition. The broad approach examines the gestalt of the troubled Sino-Japanese relations going back to the 16th century, so that the reader will be adequately equipped to grapple with the true significance of the present contention over the Diaoyu/Senkaku island. The subject matter the book addresses not only concerns the two Asian giants, but also offers a test for the United States, more especially on how it is going to lead a Pacific-centric 21st century in world politics.
