Hong Kong on Friday introduced the draft bill of a new national security law that includes life sentences for major offences such as treason and insurrection.
The homegrown legislation is set to become the city's second national security law, following the one Beijing imposed in 2020 after quashing huge and sometimes violent democracy protests.
The "Safeguarding National Security Bill" was formally introduced at the city's rubber-stamp legislature on Friday morning for vetting.
Security chief Chris Tang told lawmakers there was a "genuine and urgent need" for the new law.
"Hong Kong has undergone serious threats to national security, especially the colour revolution and black-clad violence in 2019, which was an unbearably painful experience," he said, referring to the democracy protests.
Legislative Council president Andrew Leung vowed lawmakers would "spare no effort and work together to plug the national security loophole as soon as possible".
The bill lists five new categories of offences -- treason, insurrection, espionage and theft of state secrets, sabotaging national security, and external interference.
Authorities have proposed life imprisonment as the maximum penalty for treason, insurrection, sabotage endangering national security, and incitement of members of China's armed forces to mutiny.
The bill also reworks Hong Kong's colonial-era crime of "sedition" to cover inciting hatred against China's Communist leadership and socialist system while upping the maximum penalty from two years to 10 years.
Under the proposed bill, authorities could apply to the court to detain an arrested person for up to 16 days without charge and bar them from consulting with lawyers during their detention.
As with its predecessor, the proposed new security law states that offences committed outside Hong Kong fall under its jurisdiction.
In a section closely watched by Hong Kong's foreign business community, the draft proposes a multipronged definition of "state secrets" that covers not only technology but "major policy decisions" and the city's "economic and social development".
The draft bill also criminalises the unlawful acquisition, possession and disclosure of state secrets, though it offers a "public interest" defence under specific conditions.
Hong Kong authorities have fast-tracked the bill, which was unveiled nine days after a one-month public consultation ended.
In response to the draft, the British consulate in Hong Kong on Friday urged the government "to allow time for proper legislative scrutiny" and urged that the law "align with international standards and uphold basic rights and freedoms".
City leader John Lee earlier said the city was fulfilling its "constitutional responsibility" by creating its own security law as required under Article 23 of the Basic Law, Hong Kong's mini-constitution since its handover from Britain to China in 1997.
Previous objections and concerns over potential rights infringements raised by local and overseas activists as well as some Western countries were rejected by Hong Kong officials as "deliberate smearing".
Critics say the existing security law has already eviscerated Hong Kong's political opposition and civil society, with pro-democracy politicians and activists jailed, forced into exile or silenced.
Nearly 300 people have been arrested and more than 170 charged since the Beijing-imposed security law came into force.
