Russia says no obligation to comply with U.S. sanction on North Korea

"We will carry out only sanctions which are adopted by the UN Security Council. We don't recognize one-sided American sanctions, we have no international obligations to comply with them," RIA quoted Morgulov as saying.

Morgulov also said Russia would not expel North Korean citizens who are subject to U.S. sanctions, and the U.S. special representative for North Korea had been invited to visit Moscow, RIA reported.
