Jeffrey Feltman, the United Nations undersecretary-general for political affairs, met with Foreign Minister Ri Yong Ho on Thursday, the second full day of the highest-level United Nations visit to the North since 2010.
Japan's Kyodo News said the North Korean foreign minister welcomed the United Nations official's visit to Pyongyang.
It may take a while to find out exactly what is being discussed during Jeffrey Feltman's visit this week.
U.N. Secretary General Antonio Guterres had, on several occasions, expressed his willingness to broker talks between North Korea and the worldwide community.
North Korea invited Feltman for a "policy dialogue" when Ri was in NY in September for the U.N. General Assembly, according to a U.N. spokesman. Feltman arrived in Pyongyang on Tuesday for a four-day visit, Yonhap reported.
Feltman, the highest-ranking American in the U.N. Secretariat, is the first person in that post to visit North Korea since February 2010.
However, Feltman will not be delivering any kind of message from Washington, U.S. State Department spokeswoman Heather Nauert said Tuesday.
Haley said that with the missile launch, North Korean leader Kim has made a choice "that brings the world closer to war, not farther from it".
The visit by Feltman follows the dispatch last month by China of its highest-level envoy to North Korea in two years.
