National security law can boost trust between HK and central govt

According to Article 23 of the Basic Law of the Hong Kong Special Administrative Region of the People's Republic of China, the SAR "shall enact laws on its own to prohibit any act of treason, secession, sedition, subversion against the Central People's Government, or theft of state secrets, to prohibit foreign political organizations or bodies from conducting political activities in the Region, and to prohibit political organizations or bodies of the Region from establishing ties with foreign political organizations or bodies".

Since the withdrawal of the National Security (Legislative Provisions) Bill in 2003, national security legislation in Hong Kong has been put on hold. The necessity and urgency of a national security law based on Article 23 of the Basic Law have been highlighted again, especially since the SAR government has had to deal with the worst riots in Hong Kong since its reunification with the motherland in 1997.

On Oct 31, the communique of the Fourth Plenary Session of the 19th Communist Party of China Central Committee emphasized it is important to establish and improve the legal system and law enforcement mechanism of the SAR in order to safeguard national security. Which means Hong Kong's current legal system and law enforcement mechanism are not capable enough of safeguarding local and national security.
