North Korea's economy minister left Monday for Russia, according to Pyongyang's media, amid signs of improved ties between the neighboring countries.
Ri Yong-nam, minister of external economic relations, is leading a government delegation, the Korean Central News Agency said in a brief report. It did not provide details, including his itinerary and the purpose of the trip.
A source here said Ri is expected to arrive in Moscow on Wednesday after traveling to Vladivostok and Khabarovsk in Russia's Far East.
He will return to Pyongyang early next month, added the source.
The minister's trip comes as speculation grows over whether North Korean leader Kim Jong-un will visit Russia in May to attend a World War II anniversary event. (Yonhap)
