As a member of the House Foreign Affairs Subcommittee on Asian and Pacific Affairs, I am necessarily concerned about the future role of Communist China in world affairs. A true understanding of Peking's foreign policy motives and objectives is possible only if one has a grasp of the ideological foundations and conflicts of the contemporary leaders of the Chinese Communist Party. Therein lies the value of Professor Yung Ping Chen's revised edition Chinese Political Thought: Mao Tse-tung and Liu Shao-chi. Within a compact number of pages, Professor Chen's book provides the rt~ader with a clear and ready grasp of the fundamentals of Com­ munist Chinese ideology. Although its scholarship is evident, the work's interpretation do not overwhelm the reader with lengthy quotations or confuse him with excessive speculations-difficulties sometimes associa­ ted with books about China. Instead, Professor Chen appears to have the ability to reduce complicated ideas to manageable proportions. In his revised edition, the author makes use of source material which recently has become available outside China to clarify issues involved in the "Great Proletarian Cultural Revolution." That phenomenon, which has caused so much wonder and speculation in the West, is analyzed by Professor Chen. He describes for the reader the underlying ideological factors which have emerged from the great turmoil in China, placing them within a framework of verified historical events while avoiding the pitfall of endless theorizing about situations and events inside China about which too little is yet known.
