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.

Opinion polls throughout 2017 showed Moon Jae-in as the leading candidate. Polls prior to the conclusion of the Democratic primary (which included his rivals to the nomination) had Moon at around 30% support, and polls conducted after he had won the primary showed generally consistent results of around 40% by April.
