North Korea has continued to make money by skirting U.N. Security Council resolutions, and its exports of banned commodities has generated at least $270 million since February, according to a classified report compiled by a U.N. panel and obtained by Kyodo News.

After China suspended coal imports from the North in February, Pyongyang "has been rerouting coal to other member states including Malaysia and Vietnam," the report said.

The U.N. midterm report was compiled by the so-called panel of experts made up of representatives from the Security Council's five permanent members — Britain, China, France, Russia and the United States — and Japan, South Korea and South Africa.
