The Vietnam government systematically suppresses freedom of expression, association, and peaceful assembly, and persecutes those who question government policies, expose official corruption, or call for democratic alternatives to one-party rule. Police harass and intimidate activists and their family members. Authorities arbitrarily arrest activists, hold them incommunicado for long periods without access to legal counsel or family visits, subject them to torture, and prosecute them in politically pliant courts that mete out long prison sentences for violating vaguely worded national security laws.
