Since May 2021, Lydia Wong, Eric Yan-ho Lai, and Thomas Kellogg, from the Center for Asian Law at Georgetown University, have tracked the implementation of Hong Kong’s National Security Law, tallying up arrests and prosecutions as well as assessing larger trends in the nature of such cases. In addition to hosting the two articles they have written about their findings (“New Data Show Hong Kong’s National Security Arrests Follow a Pattern” and “Arrest Data Show National Security Law Has Dealt a Hard Blow to Free Expression in Hong Kong”), ChinaFile is providing regularly-updated data about these cases on a stand-alone page: “Tracking the Impact of Hong Kong’s National Security Law.” Check back here frequently for information about new arrests or updates to cases working their way through the legal system.
