Book excerpt: This book explores the media and conflict relationship in the age of social media through the lens of China. Inspired by the concepts of medialization of conflict and actor-network theory, this book centers on four main actors in wars and conflicts: social media platform, mainstream news organizations, online users and social media content. These four human and non-human actors associate, interact and negotiate with each other in the social media network. The central argument is that social media is playing an enabling role in contemporary wars and conflicts. Both professional media outlets and web users employ the functionalities of social media platforms to set, counter-set or expand the online public agenda. Social media platform embodies a web of technological and human complexities with different actors, factors, interests, and power relations. These four actors and the macro social-political context are influential in the medialization of conflict in the social media era. ‘’Empirically rich and theoretically innovative, this book advances our understanding of the constantly changing dynamic between international conflict and its medialization. With its compelling case studies, Shixin Zhang’s monograph makes a valuable contribution to the literature on Chinese social media in conflict situations.’’ - Daya K. Thussu, Professor of International Communication, Hong Kong Baptist University, Hong Kong
