Yet the RIA original (
https://ria.ru/world/20171201/1509978423.html), referenced in that story as a source tells a different story.
That narrative (based on the quotes) being that Russia is prepared for eventualities of 3rd parties invading DPRK and thus generating a threat to Russia because DPRK is on Russian border.
Morever, that sort of resolution is viewed as undesirable, when compated to a political or a diplomatical one.
So now DPRK has a full size ICBM, capable of delivering proper sized nuclear weapons to CONUS. What a time to live in.
