HONG KONG: Jimmy Lai, the pro-democracy former Hong Kong media tycoon and a fierce critic of Beijing, was sentenced to 20 years in prison in one of the most prominent cases under a China-imposed national security law that has virtually silenced the city’s dissent.

Lai was convicted in December of conspiring with others to collude with foreign forces to endanger national security, and conspiracy to publish seditious articles. The maximum penalty for his conviction was life imprisonment. Given he is 78 years old, the prison term still could keep him behind bars for the rest of his life.

His co-defendants, six former employees of his Apple Daily newspaper and two activists, received jail terms between 6 years and 3 months, and 10 years.

Lai smiled and waved at his supporters when he arrived for the sentence. But before he left the courtroom, he looked serious, as some people in the public gallery cried. When asked about whether they would appeal, his lawyer Robert Pang said no comment.

The democracy advocate’s arrest and trial have raised concerns about the decline of press freedom in what was once an Asian bastion of media independence. The government insists the case has nothing to do with a free press, saying the defendants used news reporting as a pretext for years to commit acts that harmed China and Hong Kong.
