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.
Jang Song-thaek
During this period he was a close ally of Kim Jong-il. Jang was still in the post four years later, in April 2013. The NDC is North Korea's "de facto" supreme decision-making body; Jang's promotion made him a key executive deputy, second only to Kim Jong-il. It is speculated that the move was part of posturing to make Kim Jong-il's son Kim Jong-un the next leader of North Korea. Jang's position in North Korean politics was also ostensibly boosted by the death of Ri Je-gang, a senior leader who was tipped by Kim Jong-il as a crucial overseer of the succession campaign.
