Hong Kong’s leader said eight pro-democracy activists living in the United States, Britain, Canada and Australia will be pursued for life for alleged national security offences – dismissing criticism that the move to have them arrested is a dangerous precedent.

Chief Executive John Lee expressed his support for the police’s efforts to arrest the eight.

At his weekly media briefing, Mr Lee said anyone, including their friends and relatives, who offered information leading to their arrests will be eligible for the bounties offered by police.

“The only way to end their destiny of being an abscondee who will be pursued for life is to surrender,” he said.

The arrest warrants have been issued for former pro-democracy politicians Nathan Law, Ted Hui and Dennis Kwok, lawyer Kevin Yam, unionist Mung Siu-tat and activists Finn Lau, Anna Kwok and Elmer Yuen.

They are accused of breaching the Beijing-imposed National Security Law by committing offences such as collusion and inciting secession.

More than 260 people have been arrested under the law enacted in 2020 as part of a broad crackdown on dissent in the territory, but the rewards of one million Hong Kong dollars (£100,609) for information leading to each arrest are the first under the law.

The move quickly drew ire from the US and British governments, which took issue with the extraterritorial application of the security law.

The US said such an application of the security law is a dangerous precedent that threatens human rights.

Australian foreign minister Penny Wong also tweeted to say her country is “deeply concerned” by reports of Hong Kong authorities issuing arrest warrants for democracy advocates.

But Mr Lee has insisted extraterritorial power exists in the national security laws of many countries.

He said how overseas officials and politicians comment on the government’s moves will not change his administration’s strong belief in safeguarding national security.

“I’m not afraid of any political pressure that is put on us because we do what we believe is right,” he said.

The Chinese Foreign Ministry’s office in Hong Kong has also rejected the criticism from the US and Britain, warning “foreign interference forces” to stop shielding “criminals” immediately.

The row reflects a fresh source of contention between Beijing and the West over the alleged overseas reach of China’s enforcement agencies following the issue of China’s alleged “secret overseas police stations”.

These stations have been reported across North America, Europe and in other countries where Chinese communities include critics of the Communist Party who have family or business contacts in China.

Beijing has denied they are police stations, saying they exist mainly to provide citizen services such as renewing driver’s licenses.

But Hong Kong’s further crackdown has not stopped overseas activists from speaking up.

Mr Law, who is accused of foreign collusion and inciting secession, said on his Facebook page that the latest development shows he is again being targeted by China’s ruling Communist Party and he feels the “invisible pressure”.

He has refused to surrender.

“All I did was reasonable, justifiable and peaceful advocacy work,” the Britain-based activist said.

Mr Mung also pledged in a statement to continue advocacy work for Hong Kong labour rights abroad.

“If I were ever found guilty, my only ‘crime’ would be speaking the truth for my fellow Hong Kongers,” he said.

Hong Kong, a former British colony which returned to Chinese rule in 1997, has come under increasingly tight scrutiny by Beijing following months of mass pro-democracy protests in 2019.

Police on Monday acknowledged they will not be able to arrest the eight if they remain overseas.

Eunice Yung, a pro-Beijing politician, who is the daughter-in-law of Mr Yuen, supported the police’s move on her Facebook page, saying she cut ties with him last August.

“All his acts have nothing to do with me,” she said.
