This revised edition provides a new preface to this highly popular book. The theme of the book is China's relations with the non-Chinese world, not only political and economic, but cultural, social and technological as well. It seeks to show that China's history is part of everyone's history. In particular it traces China's relationship since the thirteenth century to the emergent world order and the various world institutions of which that order is composed. Each chapter discusses China's comparative place in the world, the avenues of contact between China and other civilizations, and who and what passed along those channels.
