U.S. responsible if diplomacy over Korea peninsula breaks down: North Korea envoy

U.S. -

U.S.—The United States will be held responsible if the opportunity for diplomacy over the Korean peninsula issue is lost, North Korea's vice foreign minister was quoted as saying by the South's Yonhap news agency on Friday.

Denuclearization off the negotiating table with U.S., North Korea’s UN envoy says. The ambassador, Kim Song, said in a statement the "sustained and substantial dialog" sought by the United States was a "time-saving trick" to suit its domestic political agenda.
