Chinese communism in 1927, city vs countryside

"This book is the result of a research venture on the narrow subject of the Chinese Communist rural and urban revolutions in late 1927 with particular reference to their relations with Moscow. As the broad lines of Comintern policy have emerged from an examination of the complicated events of the few months under study, it has turned out that those lines of policy represent a revolutionary pattern not only for China but for the whole underdeveloped world as well. In a real sense, the questions at issue in the present study are questions of world history, not just questions of the history of the Chinese Communist movement. These questions are still disturbing the world today" -- from preface.
