North Korea's next Ambassador to the United Nations Kim Song has not yet received his visa to begin work at his new post in New York, an official told Kyodo News.

He is to replace Pyongyang's previous envoy, Ja Song Nam, who left at the end of July after having served as his country's top representative at the U.N. headquarters since February 2014.

Kim apparently applied for his visa in late May through the U.S. Embassy in Beijing, but has received no indication of when the process will be completed and is unable to travel to the country in the meantime.
