This book examines religious activism—Christianity, Buddhism, and Taoism—in China, a powerful atheist state that provides one of the hardest challenges to existing methods of transnational activism. The author focuses on mechanisms used by three kinds of actors: protesters, advocates and opportunists, and uses regional, inter-faith, and international comparisons to understand why some foreign advocates can enter China and engage in illegal aid and missions to empower local activists, while the same groups cannot conduct the same activities in another geographically, economically and politically similar location. The stories in this book demonstrate a more inclusive and bottom-up approach of transnational activism; they challenge the conventional spiral theory paradigm of human rights literature and the narrow views about GONGOs in civil society literature. This new knowledge helps to sustain a more optimistic view and offers an alternative way of promoting human rights in China andcountries with similar authoritarian environments.
