TEHRAN, Young Journalists Club (YJC) - The announcement came as a high-level United Nations representative held talks with a senior North Korean official during a rare trip to Pyongyang.
Jeffrey Feltman, UN undersecretary general for political affairs, arrived Tuesday to discuss what the world body described as "issues of mutual interest and concern".
He and vice foreign minister Pak Myong-Kuk discussed "cooperation between the DPRK and the UN Secretariat and assistance from UN agencies to the DPRK and other matters of mutual interest", the North's KCNA news agency reported, using the acronym for the country's official name.
Feltman's trip -- the first by a UN diplomat of his rank since 2010 -- comes less than a week after North Korea test-fired a new ballistic missile said to be capable of reaching the United States.
Discussing ways to "peacefully resolve North Korea's nuclear issue" will be on Moon's agenda when he meets President Xi Jinping next week, Moon's office said.
Chinese foreign ministry spokesman Geng Shuang said the visit would discuss "international and regional issues of common concern" including "increasing communication and coordination on the Korean peninsula nuclear issue".
China has proposed that the North suspend missile and nuclear tests in exchange for a suspension of US-South Korean military exercises, a suggestion Washington has repeatedly rejected.
