The UK, EU and Nato have expressed concern and anger after China passed a controversial security law giving it new powers over Hong Kong.
President Xi Jinping signed the law and it is being placed in Hong Kong’s mini-constitution, criminalising sedition and effectively curtailing protests.
Hong Kong’s leader, Carrie Lam, defended the law, saying it filled a “gaping hole” in national security.
One key pro-democracy group said it was now ceasing all operations.
Demosisto announced the move on Facebook after Joshua Wong, one of Hong Kong’s most prominent activists, said he was leaving the group, which he had spearheaded.
Beijing is expected to clarify the law later on Tuesday. No draft was made public beforehand and even Ms Lam said she could not comment on its terms while the Standing Committee of the National People’s Congress discussed them.
