What methods does the North Korean government keep their citizens under control?

The government restricts all civil and political liberties for its citizens, including freedom of expression, assembly, association, and religion. It prohibits all organized political opposition, independent media, civil society, and trade unions. The government routinely uses arbitrary arrest and punishment of crimes, torture in custody, forced labor, and executions to maintain fear and control. In recent years, the government has tightened domestic restrictions on travel and unauthorized cross-border travel with China, and punished North Koreans making contact with the outside world.
