GANGNEUNG, SOUTH KOREA – FEBRUARY 08: People queue in front of an LED screen to watch a performance by North Korea’s Samjiyon art troupe at Gangneung Art Centre on February 8, 2018 in Gangneung, South Korea. In a sign of thawing bilateral ties, North Korea announced yesterday that Kim Yo-jong, the sister of North Korean leader, Kim Jong-un, will attend Friday’s opening ceremony of the PyeongChang Winter Olympic Games. Her visit will coincide with that of United States Vice President Mike Pence who on Wednesday said Washington will soon impose its harshest-ever sanctions on Pyongyang.
