HONG KONG — Hong Kong authorities once again arrested prominent activist Joshua Wong on Friday and charged him with conspiracy to collude with a foreign country under a Beijing-imposed national security law.

Wong, 28, was originally set to be released in January 2027 from a 56-month jail sentence he is serving under the same law for conspiracy to commit subversion after he participated in an unofficial primary election.

Taken to the West Kowloon magistrates’ courts, Wong faced a new charge of conspiracy to collude with a foreign country or with external elements to endanger national security.

The former student pro-democracy activist, who wore a blue shirt and appeared noticeably thinner than before, replied, “Understand,” when the clerk read out the charge and details of the offence

Wong did not apply for bail, and the case was adjourned to August 8. Before returning to custody, he waved, shrugged, and shook his head in the direction of the public gallery.
