The Hanoi People's Procuracy Friday charged Cu Huy Ha Vu with "distributing propaganda against the State of the Socialist Republic of Vietnam" under Article 88 of the Criminal Code.
The 53-year-old Hanoian faces up to 20 years in jail if convicted.
According to the indictment, between 2009 and October, 2010, Cu Huy Ha Vu had posted many materials and interviews with content against the state on the internet. For example, he called for the government be overthrown, a multi-party government introduced, and desired foreign intervention as well, according to the prosecutor's office.
These articles and interviews also maligned Party and State guidelines and policies, defamed the administration and State institutions, and blackened the Vietnamese people's resistance wars.
Under Vietnamese law, the court will now peruse the charges and consider a trial.
Vu, who was arrested last month in Ho Chi Minh City, is the son of well-known poet Cu Huy Can and a nephew of Xuan Dieu, also one of the country's most famous poets.
He obtained a doctorate in law in France and ran a law firm with his wife in Hanoi before being detained. However, Vu is not a practicing lawyer.
Last year, Vu filed petition with the Hanoi People's Court against Prime Minister Nguyen Tan Dung's approval of a plan to exploit bauxite mines in the Central Highlands, but the suit was dismissed.
