The head of rights group's China team, Joshua Rosenzweig, said on Tuesday that Beijing’s exclusion of Hong Kong’s existing legislature in drafting and passing the law shows that the People’s Republic of China aims "to govern Hong Kong through fear from this point forward."
The law, the final details of which have yet to be disclosed, will target secession, subversion, terrorism and collusion with foreign forces. 
Rosenweig called on the Hong Kong government and the international community to work to ensure that "the national security law is not used to trample human rights and undermine the freedoms that distinguish the city from mainland China.”
