North Korea is unable to pay its share of the 2018 U.N. budgets because of international sanctions on its foreign exchange bank.
South Korea said on Monday it will try to arrange more reunions for families divided by the Korean War and seek to lower military tensions with North Korea as the first steps towards establishing grounds for a rare summit between the two Koreas.
For the first time in years, a member of North Korea's ruling family has visited South Korea.
CNN's Paula Hancocks reports on the visit.
Kim Jong Un's sister, Kim Yo Jong, has visited and reactions were mixed.
