Wong, in prison since 2020, was found guilty of colluding with foreign entities in violation of the city’s national security law.

Hong Kong pro-democracy activist Joshua Wong, who has been in prison since 2020, has been jailed for an additional 10 years.

Hong Kong’s High Court found Wong guilty of colluding with foreign entities in violation of the city’s national security law on Thursday.

The sentence comes just two months before he was expected to be released in January 2027.

“The punishment must fit the gravity of ⁠the crime,” High Court Judge William Tam told a packed courtroom while delivering the sentence.

“It is also necessary for the court to express the community’s abhorrence of the defendant’s scheme and acts with others to collude with foreign forces or external elements to endanger national security.”

Wong, now 30, was accused of conspiring with self-exiled activist Nathan Law and others to ask foreign countries, bodies or individuals outside China to impose sanctions or blockades, or engage in other hostile activities against the government.

He pleaded guilty to the charge in September. Tam said he considered a 13-year prison sentence as a starting point but reduced it to 10 because of Wong’s guilty plea and mitigation.

Wong was once the face of Hong Kong’s pro-democracy movement and has been in jail since 2020. He was imprisoned over his role in protests held a year earlier.

The demonstrations were prompted by plans to allow extradition to mainland China but soon evolved into a wider pro-democracy movement. Wong became a prominent representative of the movement, regularly appearing on news channels. He later pleaded guilty to inciting and organising an unauthorised antigovernment assembly.

‘Endless political persecution’

Governments and rights groups criticised the court’s decision on Thursday.

The United States consulate in Hong Kong said that it “strongly condemns” the additional sentence handed to Wong, and called for his “immediate release”.

“Wong has been unjustly imprisoned since December 2020, demonstrating that Beijing will go to extraordinary lengths to silence those who advocate for fundamental freedoms in Hong Kong,” a consulate spokesperson said in a statement to the AFP news agency.

After his sentencing, Taiwan also criticised the “endless political persecution” of Hong Kong pro-democracy activists.

Beijing and the Hong Kong government use “authoritarian tools” to “fabricate charges … engage in endless political persecution, and suppress the people’s legitimate rights to pursue freedom, democracy, and human rights,” Taiwan’s top China policy body said.

Human Rights Watch denounced the latest charge against Wong. “The harsh sentence on baseless charges against Joshua Wong is cruel and unjust. Young people promoting social change are an asset for any vibrant society, but the Hong Kong government puts them behind bars,” said Elaine Pearson, the group’s Asia director.

Amnesty International also criticised Wong’s additional sentence, saying it was “another grim reminder of how Hong Kong’s National Security Law has become a tool to punish dissent”.
