Hongkongers' International Front: Diaspora Activism During and After the 2019 Anti-Extradition Protest.

The flare-up of protests over Hong Kong's anti-extradition bill amendment in 2019 gave rise to a global wave of organising among the city's overseas diaspora of students and migrants, persisting after the city's protest movement declined due to COVID-19 and repression. Based on 85 in-depth interviews with overseas activists as well as journalistic and social media data on events in six cities, this article examines the diaspora's pro-democracy campaign. Easily surpassing the previous mobilisational waves of 1989 and 2014, the newer diaspora activism gave rise to more numerous and widespread organisations, which were mostly decentralised and loosely connected. Responding to the rise and fall of protests in the home city, campaigners shifted from supplying protest-related gear to sheltering fleeing refugees, with the diaspora activism evolving into a global resistance against China's authoritarian expansion. Counter-protests by pro-China supporters increased publicity for the campaign, but also brought threats to personal safety. With the exception of Taiwan, Hongkongers found it difficult to localise their agenda in host countries, and their efforts were frustrated by growing political polarisation in Western democracies.
