The sentence for the media mogul, along with long prison terms for his editors, shows how Hong Kong enforces Xi Jinping's red lines with a new severity.
A Hong Kong court sentenced 78-year-old activist and publisher Jimmy Lai to 20 years in prison after finding him guilty under China's national security law.
Two editors and an opinion writer from Jimmy Lai's now-shuttered newspaper were each sentenced to 10 years in prison, a significant escalation in media prosecution in the once freewheeling city.
