It looks like Kim Jong-un got cold feet and decided not to travel to Russia after all:
South Korea sees no abnormal signs in North Korea which might have caused its leader, Kim Jong-un, to cancel his planned trip to Russia next week, a Defense Ministry official said Friday.
On Thursday, a spokesman for Russian President Vladimir Putin told reporters that the North Korean leader will not visit Moscow for a celebration to mark the 70th anniversary of the end of World War II, saying that the decision “is related to internal Korean affairs.”
South Korean and Russian officials had expected the leader of the reclusive nation to attend a military parade and hold a bilateral meeting with Putin. It would have been his first foreign trip since taking office in 2011 upon the death of his father, Kim Jong-il.
“We don’t believe that any notable internal affairs are taking place in North Korea (that are) serious enough to cause Kim not to attend the event,” the official said, requesting anonymity. [Korea Times]
