Ling Li unveils the often-hidden inner workings of the Party as the ruler of a party-state. The Party has crafted and relied on an integrated regulatory system, where politics and law are fused, to govern both its internal operations and its relations with the state. Drawing on two decades of in-depth research, Li delves into the “black box” of decision-making in the Party-state, analysing the motivations and strategies driven individual and institutional choices in corruption, anti-corruption investigation, and power struggles at the Politburo. This insightful book reveals the critical role of rules and institutions within the Party, illuminates the complex relationship between corruption and regime stability, and captures the evolving dynamics of the Party-state relations. A must-read for students, academics, business leaders, and policymakers alike, this book is a vital guide for anyone who seeks a nuanced understanding of law, politics and governance in China and its global implications.
