In a move seen by some as a clampdown on freedoms in Hong Kong, the government has banned a political party for the first time since the former British colony was handed back to China in 1997.
The decision to prohibit the operation of the Hong Kong National Party, whose declared goal is to make Hong Kong a republic, was announced in a government notice published yesterday.
Mr John Lee, Secretary for Security, told reporters: "In the course of achieving its aims, the Hong Kong National Party also spreads hatred and discrimination against mainlanders in Hong Kong."
The party had used the term "armed revolution", he said.
"It has also made it very clear that it will make use of all means to achieve its goals and this includes the option of using force."
The ban on the party, which the Hong Kong government had been mulling over since July, is based on the Societies Ordinance which allows the prohibition of groups for reasons of national security, public safety and public order. The colonial-era law was primarily used to target triads previously.
Mr Andy Chan Ho Tin, the party's co-founder and convener, told The Straits Times last month that he was "expecting an actual ban on our party" and said he had plans for different kinds of situations.
Mr Chan's party has 30 days to appeal against the ban.
Mr Chan made the news last month when he advocated for Hong Kong independence at the Foreign Correspondents' Club, which went ahead with the event despite a request from China's Foreign Ministry to cancel it.
The Hong Kong and Macau Affairs Office of China's State Council voiced resolute support for the ban, saying the central government has zero tolerance for groups preaching Hong Kong independence, Xinhua news agency reported.
Mr Lee dismissed the notion that he had been influenced by the mainland authorities, and stressed that Hong Kong citizens continue to have freedoms, but that these are not absolute. He said the unregistered Hong Kong National Party has, over the past two years, made moves to achieve its goal of making Hong Kong independent from the mainland. It had tried to enter the 2016 Legislative Council election and infiltrated schools to recruit members and win support.
As to whether other pro-independence groups are also under review, Mr Lee said enforcement agencies "will act according to the law to deal with the situations".
Professor Willy Lam of the Chinese University of Hong Kong told ST that other anti-Beijing parties, such as the Hong Kong Indigenous, Hong Kong National Front, and Demosisto, may be next in line to be scrutinised by the authorities.
There are also fears that the ban will intimidate moderate parties such as the Democratic Party.
Still, Prof Lam said: "At this stage, they don't have the legal justification to incriminate or to threaten other pro-democracy parties until Article 23 is passed and, of course, you have to wait and see the wording of Article 23."
Prof Lam said the ban is also meant as a step towards ensuring a smoother roll-out of Article 23, which he believes would be introduced before Chief Executive Carrie Lam's term ends in 2022.
Under Article 23 of the Basic Law, the territory's mini Constitution, Hong Kong must enact its own national security legislation to prohibit treason and subversion against Beijing.
Article 23 has been a political hot potato for the Hong Kong government, whose last attempt to enact the legislation prompted half a million people to take to the streets in protest on July 1, 2003. The Bill was subsequently shelved.
