Groups of protesters gathered in the entertainment district of Mongkok, to protest Beijing’s plans to pass a bill on national security in this special administrative region of China.
After several warnings to the protesters and calling them to disperse, the police used force including pepper spray and tear gas.
The protesters acted calmly, did not carry out any riots, and did not show any aggression towards the police, according to local media.
There were massive protests in the region against the law demanded by the Chinese government in Hong Kong in 2003; However, Beijing was later forced to retreat.
Article 23 of the Hong Kong Basic Law allows the local government to pass laws against – plans and attempts – “destroying the central government, encouraging insurgency, and treason crimes” if necessary.
The Hong Kong National Security Law is the most important in the region to enhance the influence of the Beijing government.
Earlier this month, the UN High Commissioner for Refugees, Michel Bachelet, said that she was closely following the intention of China to issue a controversial new security law in Hong Kong, calling on Beijing to fully comply with international human rights obligations.
On Friday, Bachelet issued a statement on the “Hong Kong National Security Law” as China aims to strengthen the government’s grip on anti-groups.
Bachelet said that independent United Nations human rights experts, including the Office of the United Nations High Commissioner for Human Rights and the United Nations Committee Against Torture, have expressed fears that the National Security Law adopted in mainland China in 2015 does not meet the standards International Human Rights. “
She stressed that laws related to national security must be clear in terms of scope and definition, and only allow restriction of human rights in “mandatory situations” and “proportionately”.
She said, “There must be meaningful legal and judicial oversight in the implementation of such legislation, and these laws cannot be used at all to punish behavior and expressions protected under international human rights law.”
Lu Huining, director of the Hong Kong Liaison Office, had called for “the promulgation of the National Security Law to combat external interference, pro-separatist violence and radical violence.”
