Foreign relations of North Korea
In 2017 Moon Jae-in was elected President of South Korea with promises to return to the Sunshine Policy. In his New Year address for 2018, North Korean leader Kim Jong-un proposed sending a delegation to the upcoming Winter Olympics in South Korea. The Seoul–Pyongyang hotline was reopened after almost two years. North and South Korea marched together in the Olympics opening ceremony and fielded a united women's ice hockey team. North Korea sent an unprecedented high-level delegation, headed by Kim Yo-jong, sister of Kim Jong-un, and President Kim Yong-nam, as well as athletes and performers.
Ro Su-hui
Ro was arrested in July 2012 after he returned (via the Joint Security Area in Panmunjom) from an unauthorized visit to North Korea, where he called for the reunification of the two Koreas and bitterly criticized President Lee Myung-bak of South Korea for his hard-line North Korea policy. He had entered the North via China in March for a memorial service marking the 100th day since the death of ruler Kim Jong-il. In February 2013, he was sentenced to four years in prison, and the Seoul Central District Court also ordered that his rights, such as suffrage, be stripped for three years after his release from prison. He was released from prison in July 2016.
