Drawing from technical, legal, and political sources, ONI's research finds that the Socialist Republic of Vietnam is focusing its filtering on sites considered threatening to its one-party system. Furthermore, the technical sophistication, breadth, and effectiveness of Vietnam's filtering are increasing with time.
Similar to China, Vietnam has taken a multi-layered approach to controlling the Internet; Vietnam applies technical controls, the law, and education to restrict
its citizens' access to and use of information. Vietnam is carrying out this
filtering with a notable lack of transparency - while Vietnam claims its blocking efforts are aimed at safeguarding the country against obscene or sexually explicit content, most of its filtering efforts are aimed at blocking sites with politically or religiously sensitive material that could undermine Vietnam's one-party system. This is the latest in a series of case studies that address Internet filtering by states worldwide.
