Hong Kong authorities criticized a British government proposal for the repeal of a China-imposed national security statute, which the UK claimed was used to pursue, “silence, and discredit” pro-democracy opposition activists.

Britain’s Foreign Secretary, James Cleverly, stated in his government’s latest six-monthly report on Hong Kong that he had highlighted at a United Nations hearing in February how Hong Kong authorities had used the security law to crack down on opposition figures, many of whom are imprisoned or forced into exile.

Cleverly called on Beijing to implement recommendations made in an independent U.N. Human Rights Council report last July, including “removing the National Security Law” that Beijing imposed on the former British colony in 2020.

Hong Kong authorities said in a statement that they “vehemently refuted, strongly disapproved and firmly rejected the slandering remarks and ill-intentioned political attacks”.

A Hong Kong government spokesman said Britain should “stop interfering in Hong Kong matters, which are purely China’s internal affairs”.

The spokesman said Hong Kong’s security law had brought stability after mass pro-democracy protests in 2019, and that while Hong Kong laws guaranteed certain individual rights, “such rights and freedoms are not absolute” when it comes to safeguarding national security.

Britain referred in its report to the erosion of Hong Kong’s rule of law, including transferring “powers once vested in the judiciary” to Hong Kong’s pro-China leader, and the inability of those facing national security charges to challenge government decisions in the courts.

“We have stood with our partners in condemning the steady erosion of civil and political rights and Hong Kong’s autonomy,” Cleverly wrote in a foreword to the report.

Among those who have been persecuted, Cleverly referred to jailed media tycoon Jimmy Lai, who faces a national security trial in September, and said he had raised Lai’s case with Chinese Vice President Han Zheng this month.

The 75-year-old Lai founded the pro-democracy Apple Daily newspaper that police raided and shut down in 2021.

Britain handed Hong Kong back to China in 1997 under an agreement guaranteeing its freedoms for at least 50 years.

While relations between London and Beijing have been strained since Beijing imposed the national security law, a senior British official visited Hong Kong this month, the first such visit in five years.
