Back in 2003, the Hong Kong government's forceful attempt to pass a similar piece of legislation in the local legislature was met with uproar from civil society and was aborted. The undemocratic nature of the government proved to be its Achilles' heel.
More than 15 years later, the legitimacy of the local and central governments faced yet another major challenge amid the 2019 anti-extradition bill movement. But now, Beijing has taken advantage of the global covid-19 pandemic and initiated a series of assaults against Hong Kong's autonomy while the international community has its hands tied by the virus. It first attempted to institutionalize the “supervisory power” of China's Liaison Office in the city. The NPC is now further attacking “one country, two systems” by circumventing Hong Kong's Legislative Council: It legislates by way of inserting the national security law directly to the Annex III of the Basic Law, Hong Kong's constitution, which will later simply be promulgated by the Hong Kong government.
