During the COVID-19 lockdowns in Vietnam last year, blogger Bui Van Thuan took to Facebook to criticise a government plan to use soldiers to deliver groceries to people confined to their homes in Ho Chi Minh City. Days later, he was arrested.

Thuan, 41, a former teacher in the country's northern province of Hoa Binh, was last month sentenced to eight years in prison for propaganda, and a further five years of probation.
