Meanwhile, a series of preparatory visits have begun. A DPRK delegation is visiting venues in eastern South Korea for art troupe performances during the Olympics . The seven-member advance team is led by musician Hyon Song Wol. The team crossed the land border earlier to reach Seoul and then traveled by bullet train to Gangneung city. It's the first visit by delegates from the north since South Korean President Moon Jae-in took office. DPRK sports officials will inspect Olympic venues later this week.
