The current Hong Kong situation is the product of a long-term accumulation of crises and the consequences of the broader interplay of clashes among nations. Taiwan has long seen the PRC's treatment of Hong Kong as a barometer of its Taiwan policy. The “One Country, Two Systems” formula was proposed with an eye on Taiwan. In recent years, Beijing seemed to decouple the Hong Kong-Taiwan nexus as it began to turn the screws on Hong Kong. Taiwan has played a significant but often misunderstood role in Hong Kong's resistance to Chinese domination. This article explores the political impact of the Hong Kong-Taiwan civil society nexus from the early 2010s, through the Umbrella Movement (2014), to the Anti-Extradition Movement (2019) and the implementation of the National Security Law (2020). The ever-more repressive measures China imposed on both Hong Kong and Taiwan have given rise to close and lively exchanges between both civil societies. Taiwan may play a supporting role in Hong Kong's resistance to Chinese repression and subordination.
