The export of banned commodities last year raised nearly $200m, a panel of UN experts says.
North Korea earned nearly $200m (£141m) last year by exporting banned commodities in breach of international sanctions, a UN report says.
The report by a panel of experts said several countries including China, Russia and Malaysia had failed to stop the illegal exports.
It said there was evidence of military co-operation with Syria and Myanmar.
Pyongyang is subject to sanctions from the US, UN and EU over its nuclear and ballistic missile programmes.
But the report, which was submitted to the UN Security Council, said the North “continued to export almost all the commodities prohibited in the resolutions… between January and September 2017”.
The report said several unnamed multinational oil companies were being investigated for their alleged role in supplying petroleum products to North Korea.
