This was worked out in New York City through some outfit called "New York Channel" apparantly connected to the United Nations.
A South Korean TV station said Clinton was not accompanied by any senior US government officials.
Chinese Xinhua news service at Pyongyang could not get any comment at all out of Clinton. When they went to the North Korea PR officials, they also refused to say anything about Clinton's visit and objective.
Then this doesn’t have the State Dept’s approval.
