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.
Workers' Party of Korea
The WPK is organized according to the Monolithic Ideological System and the Great Leader, a system and theory conceived by Kim Yong-ju and Kim Jong-il. The highest body of the WPK is formally the Congress, but in practice a Congress occurs infrequently. Between 1980 and 2016, there were no congresses held. Although the WPK is organizationally similar to communist parties, in practice it is far less institutionalized and informal politics plays a larger role than usual. Institutions such as the Central Committee, the Executive Policy Bureau, the Central Military Commission (CMC), the Politburo and the Politburo's Presidium have much less power than that formally bestowed on them by the party's charter, which is little more than a nominal document. Kim Jong-un is the current WPK leader, serving as Chairman and CMC chairman.
