Marvin Kalb presents a clear exposition of the known facts concerning the alliance between Red China and Russia. Due to censorship control within the countries much remains shrouded in mystery regarding this powerful partnership but it is apparent that a real and ideological contradiction separates the two communist nations. This is climaxed by China's hard line, toward the West- of inevitable war, and Russia's flexible policy of ""peaceful coexistence"". The author traces the basic political cleavage beneath a seemingly united front. Chinese Communism succeeded without aid from Russia. Early it took an agrarian rather than proletarian approach which culminated in the establishment of the communes. The Chinese have felt that they are the natural heirs of the Marxist-Leninist legacy on the basis of color and affinity to the Asian bloc. Far from being definitive the book nevertheless states the case concisely. The Chinese-Russian relationship still is a well-cemented alliance. But competition as to which nation will eventually maintain leadership with the Socialist world threads throughout the alliance. What is said in these pages has the stamp of sound documentation and solid reasoning.
