On Feb. 3, North Korean leader Kim Jong-un sent out Lunar New Year greeting cards to international allies. For the third year in row Russia was listed at the top of the list of friendliest countries, relegating China to second place.

The Chinese President Xi Jinping has yet to meet with Kim Jong-un since he assumed power five years ago.
