Russian President Vladimir Putin and North Korean leader Kim Jong Un signed a "strategic partnership treaty" on Wednesday that included a mutual defense pledge, upgrading relations to a level that Kim said was on the same level as a formal alliance.
"The comprehensive partnership agreement signed today provides, among other things, for mutual assistance in the event of aggression against one of the parties to this agreement," Putin said.
