A UN report says, North Korea earned nearly 200 million dollars last year by exporting banned commodities in breach of international sanctions. <br/><br/>The confidential report by a panel of experts said, several countries including China, Russia and Malaysia had failed to stop the illegal exports. <br/><br/>It said, there is 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. <br/><br/>But the report, which was submitted to the UN Security Council and seen by news agencies, said the North continued to export almost all the commodities prohibited in the resolutions between January and September 2017. <br/><br/>The report said, several unnamed multinational oil companies are being investigated for their alleged role in supplying petroleum products to North Korea. <br/><br/>It said, shipments of coal had been delivered to China, Malaysia, South Korea, Russia and Vietnam in breach of sanctions using a combination of multiple evasion techniques, routes and deceptive tactics.<br/><br/>China's embassy in North Korea denied flouting Security Council sanctions, but said in a statement that the two neighbours had maintained normal trade exchanges.
