Amidst the vast sea of literature that exists on the diplomatic history of the world between the two World Wars, J.C. Johari’s book stands out as a remarkable piece of work. Reflecting thorough research and analysis, it has been revised and enlarged in order to include the history of the Middle East and the Far Eastern countries like Japan and China. An account of the interwar period may be called a study of the diplomatic history of the major European powers. The major countries of the West were involved in various forms of commitments and negotiations. In a way, these efforts started the trend of “global negotiations”, which the governments of the major countries practised in order to achieve their ends, not only during the times of war but also during the times of peace. It is hoped that this book will serve the requirements of students offering this course for graduate and post-graduate examinations as well as for competitive examinations.
