This article addresses the return of popular protests in Hong Kong in 2020, after the government's adoption of emergency measures to address the COVID-19 pandemic in Hong Kong and following calls by the Chinese Communist Party for the government to take a much more repressive stance against protests. The pandemic has also accelerated the downturn in U.S.-China relations. The article reviews the parallel, and at times intersecting, evolution of popular protests and pandemic control measures in Hong Kong. It also outlines the ways in which the 2019 protests were departures from previous protest cycles.
