Are Marx's publications censored in North Korea?

My understanding is that like Cambodia under the Khmer Rouge, Marxist ideology in North Korea has been officially renounced (in favour of 'Juche'). Although Bonapartism is identified as a precursor to fascism rather than Stalinism, anyone in North Korea couldn't help reading the Eighteenth Brumaire of Louis Napoleon and draw parallels (albeit in a very general context) between the agendas of Kim Il-Sung and Kim Jong-Il and that of Louis Bonaparte.
