Kwok Yin-sang, the father of pro-democracy activist Anna Kwok, has been sentenced to eight months in prison by a Hong Kong court for a national security violation - the first involving a family member of a wanted activist abroad.

The 69-year-old was accused of attempting to handle the financial assets of Anna Kwok, who left Hong Kong in 2020 and is wanted by Hong Kong authorities.

He was convicted earlier this month under Article 23, a homegrown law that expands on the Beijing-imposed national security law.

Authorities say the laws, which target acts like treason and secession, are necessary for stability - though critics say they are tools to quash dissent.

Anna Kwok, who is now based in the US, is one of 34 activists wanted by Hong Kong's national security police.
