SEOUL, July 8 (UPI) -- North Korean leader Kim Jong Un has been urging his reclusive nation to keep up with the rest of the world in a range of different areas.
Kim has used the term "global trends" during recent official visits to an airport, a cancer research center and a sock factory, which some analysts say could be a signal to upgrade and even open up the nation's economy, South Korea's Yonhap news agency said Sunday.
