Joshua Wong, who became the face of Hong Kong’s pro-democracy movement as a teen before being ensnared in China’s crackdown on the territory, has been sentenced to 10 years in prison.

A Hong Kong court on Thursday found Wong, now 30, guilty of conspiring to collude with foreign entities, including calling for U.S. sanctions on Hong Kong, a charge that human rights organizations have decried as baseless and cruel. Wong has been in custody since 2020 and was set to be released early next year under previous sentences. He will now remain in prison for nearly a decade longer.
