Wong, 30, has been imprisoned since 2020 and is the only activist in Hong Kong prosecuted twice under national security law

Hong Kong activist Joshua Wong has been sentenced to 10 years in prison after earlier pleading guilty to “foreign collusion”, his second conviction under a national security law that critics say has been used to silence political opposition in the city.

Wong, who rose to prominence as the teenage face of Hong Kong’s 2014 pro-democracy demonstrations, submitted his guilty plea in September. He had been accused of working with the exiled Hong Kong activist Nathan Law to urge foreign powers to impose sanctions, blockades or other hostile measures against China.
