The UN Human Rights Council on Thursday launched a formal investigation into North Korea's alleged gross violations of human rights, DPA reported.
The resolution that was drafted by Japan and EU countries said that this should be done "in particular where these crimes may amount to crimes against humanity."
One of the three commission experts is Marzuki Darusman, the current UN rapporteur on human rights in the Democratic People's Republic of Korea (DPRK).
In his recent report, Darusman focussed especially on what he called the "political concentration camps" in the Communist country, where an estimated 200,000 people are being held.
North Korean Ambassador So Se Pyong said "the draft resolution is no more than an instrument that serves the political purposes of the hostile forces in their attempt to discredit the image of the DPRK and to change the socialist system chosen and developed by our people."
