The book is part of the recent effort to catch up with the research on the Chinese Communist Party (CCP). Despite its omnipresence and pivotal role in running the country, there has been a conspicuous shortage of references to the Party in most studies related to China. In its stead, the academic literature as well as popular discussions has too often treated the CCP as a type of regime destined to the dustbin of history. The inadequacy of research in this area is understandable because CCP is a tightly organised Leninist party which has kept much of its internal affairs confidential. This book examines the key aspects of the transformation of CCP in the rapidly changing national and global context. It highlights the problems faced by the ruling Leninist party in adapting to a capitalistic environment that its organisations cannot fully control and its ideology cannot effectively rationalise. It also examines CCP's strategies for adaptation in the areas of ideological reformulation, party-society relations and the ways of exercising power and maintaining internal cohesion. In addition to helping the readers understand how China is ruled and how the Chinese system operates, the book also highlights the evolutionary dynamics of Chinese politics in the environment created by CCP's reform and open-door policies.
