Olympics chief Thomas Bach dismissed concerns that North Korea had tried to "hijack" the competition for political gain. An IOC spokesperson told French news agency AFP that “no dates have yet been confirmed."
He added that the visit was part of the January agreement which confirmed North Korea's participation at the Games.
Meanwhile, the IOC came under fire over a snowbording event as high winds caused havoc at the Winter Games on Monday, causing many to fall down.

While the skiing was postponed, the slopestyle went ahead with near-farcical results, as athlete after athlete hit the deck including gold medal-winner Jamie Anderson.
"The weather was bad and too dangerous," said bronze medallist Enni Rukajarvi, while Austria's Anna Gasser added: "So many people got hurt because of the wind."
The International Ski Federation (FIS) admitted that conditions were "challenging" but defended the decision to go ahead with the event.
"FIS always aims for the athletes to be able to stage their best performances, which some athletes have expressed was not the case today," a statement said.
"But the nature of outdoor sports also requires adapting to the elements."

In North Korea, these, and most other Olympic events are not covered at all in the state-run press.

Only hidden in the sports pages are only four articles related to the Olympic Games, but they focus on the Taekwondo demonstration by the joined Korean team and there is an article about how the North Korean delegation watched Ice hockey “with S. Korean president.” In the North Korean press, there is no mention of any scores, and medal tables with overall standings are absent.
