North Korea has urged the United States to adopt a "serious attitude" to contribute to maintaining peace and stability on the Korean peninsula.
Ri Jong Hyok, director of North Korea's National Reunification Institute and deputy head of its Supreme People's Assembly,
was speaking at the Inter-Parliamentary Union (IPU), in Geneva.
He said his country sought to build a "just and peaceful new world, free from aggression and war" and nothing could block the goal of inter-Korean dialogue and reunification.
