Vietnam intensified its grip on old and new media through a campaign of censorship, surveillance, and imprisonments. Central Propaganda Department officials held weekly meetings with top newspaper editors, outlining news agendas and identifying banned topics. The list of prohibited topics expanded to include criticism of the government's economic management, land conflicts between the state and local communities, and the business dealings of the prime minister's daughter, CPJ sources said. Courts handed down harsh prison sentences to six journalists in 2012. Nguyen Van Khuong, a reporter with the Vietnamese daily Tuoi Tre, was sentenced to four years in prison on trumped-up bribery charges filed after he investigated police corruption. Bloggers Dinh Dang Dinh and Le Thanh Tung were sentenced to six and five years respectively for postings deemed critical of the ruling Communist Party. Three other bloggers--Nguyen Van Hai, Ta Phong Tan, and Phan Thanh Hai--were sentenced to terms ranging from four to 12 years on anti-state charges related to their critical journalism. An executive decree pending in late year threatened a further clampdown on the Internet, including new prohibitions against pseudonymous or anonymous blogs. In a September directive, Prime Minister Nguyen Tan Dung called for police to identify and arrest contributors to three critical, politically oriented blogs that had been operated anonymously. The directive also ordered that the sites be blocked domestically.
