This afternoon, Phnom Penh Municipal Court sentenced university student Kong Raya, 25, to 18 months’ imprisonment for calling for a “colour revolution” on his Facebook page. His conviction represents the latest development in a growing trend for authorities to take action against online expression.

Kong Raya, the president of Cambodia Student Network, was arrested for his Facebook comments on August 20 – less than a month after Prime Minister Hun Sen called on police and armed forces to take action over any group or individual attempting a “colour revolution”. He was charged with criminal incitement under Articles 494 and 495 of Cambodia’s criminal code and sent to CC1 prison. With today’s sentence he is set to remain incarcerated for almost another year.
