It was clear at the release of Hong Kong’s National Security Law that it unapologetically brought HK more directly under Mainland China’s oversight. It created central government institutions in Hong Kong, took greater control of Hong Kong authorities. The new law directly imported the mainland’s criminal procedure for some crimes ‘endangering national security’ and expanded police powers.
There has been some confusion about how new national security legislation pushed through in Hong Kong (HKNSL) relates to mainland China’s National Security Law (NSL) and other legislation. A number of people have asked me to compare the two ‘National Security Laws’, but they are sufficiently different in character that a direct comparison might not make sense.
