This paper describes the recent emergence of alternative food networks in China in the context of widespread food quality concerns. Drawing on interviews and public blog posts, we illustrate how participants in these networks are moving beyond instrumental market relations and developing the collective agency necessary to participate in shaping China's food system. We argue that the initiators and participants in these alternative food networks are not only individual shoppers who ‘vote with their chopsticks’, but are also nascent activists deploying grassroots community organising strategies. We reveal how these networks are using inclusive and reflexive processes to build diverse networks, how they are using internet communications to extend their reach, voice dissent and engage in nascent ‘bottom up’ policy formation, and how they are building influential connections and actively, but unofficially, expanding linkages to broader emancipatory spaces of global and social justice movements.
