Proactive internationalization and diaspora mobilization in a networked movement: the case of Hong Kong’s Anti-Extradition Bill protests

One distinctive feature of the 2019 Anti-Extradition Bill Movement in Hong Kong is the ‘international front’ on which both Hong-Kong-based activists and members of diaspora communities engaged in public diplomacy and foreign government lobbying. While the emergence of the international front can partly be explained by perceived political opportunities and protesters’ identity change, this article focuses on the evolution of mobilizing structures. Of particular interest is how the mobilizing structures were activated, expanded, and transformed in a protest campaign marked by certain core features of networked social movements. Based on in-depth interviews with twenty activists, the analysis illustrates the co-presence of and complementarity between digitally enabled, citizen self-initiated actions and organization-based mobilization. The analysis also shows how tactical shifts, negotiation of differences among activists, and state response drove the transformation of activist network. General theoretical implications on understanding of diaspora mobilization and networked social movements are discussed.
