A UN report has revealed that North Korea earned nearly 200 million U.S. dollars in illegal exports last year, violating international sanctions.
The confidential report, seen by Reuters, said that North Korea "continued to export almost all the commodities prohibited in the UN resolutions between January and September 2017".
Countries involved in trade with the rogue state include China, Russia and Malaysia.
North Korea is also said to have supplied weapons to Syria and Myanmar, including materials for ballistic weapons technology and chemical weapons manufacturing.
Coal is also said to have been exported to several countries, including South Korea, using, quote, "a combination of multiple evasion techniques, routes and deceptive tactics".
Several unnamed multinational oil companies are also said to be under investigation for trade in petroleum products.
