North Korea is probably the most corrupt country in Asia. Measuring corruption levels is difficult, and existing ratings (like the well-known index published annually by Transparency International) should be taken with a pinch of salt. Nevertheless, anecdotal evidence appears persuasive enough: Official corruption in North Korea has been exceptional over the last 20 years.
In my frequent discussions with North Koreans, I have discovered the fact that most of them take a high level of corruption for granted. They assume that any official who is in a position to ask for bribes will. In fact, they are surprised if officials refuse bribes. Simply put, corruption is part of the fabric of daily life in North Korea today.
