China’s ruling Communist Party has set in motion a controversial national security law for Hong Kong, a move seen as a major blow to the city’s freedoms.
The law to ban “treason, secession, sedition and subversion” could bypass Hong Kong’s lawmakers.
Critics say Beijing is breaking its promise to allow Hong Kong freedoms not seen elsewhere in China.
Pro-democracy activists have called for mass protests against what they see erosion of Hong Kong’s autonomy.
Anger was already apparent on Friday, as a group of protesters descended on China’s Liaison Office in Hong Kong.
