Twenty Neighbors in Asia

China shares borders with 20 other countries. Each of these neighbors has its own national interests, and in some cases, these include territorial and maritime jurisdictional claims in places that China also claims. Most of these 20 countries have had a history of border conflicts with China; some of them never amicably settled. This book brings together some of the foremost historians, geographers, political scientists, and legal scholars on modern Asia to examine each of China’s twenty land or sea borders.
