This book can provide enough information about the history of ｄiplomatic affairs. But the author started the writing from the origin of diplomatic history in Europe as the history of world diplomatic affairs. Moreover, the final part of the book stoped at the period of diplomatic affairs too far before economic crisis in Asia so this may make the author's predict about Asia and China seem blurr and incorrect in the future. However, diplomatic affairs is an story that nobody can predict correctly. With the detail he wrote and history about the affairs it can provide some strong basic for diplomatic affairs in the present world !
