Hong Kong Chief Executive Carrie Lam has expressed her intention to implement a security legislation which has long met strong public opposition.
Lam outlined policies for the next one year in her address at the Legislative Council, Hong Kong's legislature, on Wednesday.
Hong Kong's Basic Law calls for the territory to enact laws on its own to prohibit any act of treason.
The Hong Kong government submitted the bill to the Legislative Council in 2003, but it was withdrawn after a protest rally that drew half a million participants.
Anti-government protests have since been restricted and election systems have been changed, making it difficult for pro-democracy candidates to run in elections.
Pro-Beijing forces are now almost certain to secure a majority in the Legislative Council election scheduled for December.
The Hong Kong government is believed to be aiming at having the legislation enacted by next June, when Lam's current term expires.
The legislation is expected to include articles that prohibit sedition, theft of state secrets and other acts.
If enacted, it could lead to a harsher crackdown of anti-government movements. It would be in force along with the Hong Kong National Security Law implemented by the Chinse government last year.
