SEOUL (Reuters) -North Korean leader Kim Jong Un told Russia's top diplomat his country was ready to "unconditionally support" all actions taken by Moscow to resolve the conflict in Ukraine, state media reported on Sunday, as the two countries held high-level strategic talks.

It was reported last week that North Korea plans to triple the number of troops fighting with Russia along the front lines in Ukraine—sending an additional 25,000-30,000 troops. Troops will arrive in the next few months, adding to the 11,000 North Korean troops that were sent in November.
