“Under such laws, vocal Hong Kong clergy who have been supportive of Hong Kong’s democracy movement, such as Cardinal Joseph Zen and Auxiliary Bishop Joseph Ha Chi-shing, could be extradited to mainland China to be tried, since Beijing considers them to be threats to the regime,” International Christian Concern (ICC), a U.S.-based Christian watchdog, said in a statement as quoted by Fox News.

“Other hundreds of protestant leaders or Christian organizations who have actively spoken out against the Hong Kong government might face the same fate, since Beijing has said it considers the mass protests that began last June as terrorist acts and any calls for Hong Kong’s independence from China as acts of sedition."

Hong Kong pastor Alan Keung, 28, joined a protest which turned violent.

Hong Kong, a former British colony, was handed over to China in 1997, and the Basic Law preserves its autonomy as a Special Administrative Region under the principle of “one country, two systems”.

The new security law will also be overriding any local laws that come in conflict with it, BBC reported.

The planned law has sparked protests against the Chinese government and also drawn international condemnation.
