Media in North Korea are under some of the strictest government control in the world. […]

The North Korean government places stringent restrictions on foreign reporters, visitors, and even residents of foreign origin. Freedom of movement is severely curtailed, interactions with local people are supervised, and photography is heavily regulated. Because of this reporters often find it difficult to check stories and establish hard facts. North Korean and Western journalists have different understandings about the role of the media. (The situation is different for Russian and Chinese journalists reporting on North Korea). North Koreans expect Western journalists to behave like Soviet journalists during the Cold War, while Western journalists would like to exert the freedom of the press more widely. Researching topics like prison camps are out of bounds, and North Korean officials are often reluctant to give statements on the record. As with tourists, foreign journalists are always accompanied by minders, and any encounters with locals have been arranged.
