Russian President Vladimir Putin and North Korean leader Kim Jong Un have signed a partnership that includes a vow of mutual aid if either country is attacked. The two leaders met for two hours in Pyongyang.

Kim says that the deal is the “strongest-ever treaty” between the two nations, putting the relationship at the level of an alliance. And Kim vows full support for Russia's war in Ukraine. 

Putin says that it's a “breakthough document,” reflecting shared desire to move relations to a higher level.

Western powers have worried that North Korea could send Russia munitions for its war in Ukraine. And in return, Russia could give North Korea technology it can use to enhance its nuclear weapons program.
