2012 was a year of crackdowns on free expression in Vietnam, including the introduction of new censorship laws. But just as important as the new regulations was the ongoing harassment, intimidation, and detainment of bloggers who had spoken out against the Communist regime. Dozens of social activists were arrested, some of whom received harsh prison sentences, and many of whom have been detained for over a year without trail. In the summer, the mother of imprisoned Vietnamese blogger Ta Phong Tan died after setting herself on fire to protest her daughter’s detention on charges spreading anti-state propaganda.
