We all know the relationship between the USA and North Korea and how the two presidents keep threatening each other. I know that the majority of the EU stands with Trump in this matter, but do we know how Vladimir Putin and Russia views North Korea? Are Russia and North Korea allies? Enemies? Neutral?
North Korea has a history of good economic, if not diplomatic, ties with Russia stretching back to the Soviet era. To call them allies today would be inaccurate, but Russia has a vested economic interest in finding a diplomatic solution to the current tension in the Korean peninsula.
Russia has supported the most recent UN resolution for greater sanctions on North Korea following bomb tests, but has also said it would be willing to mediate talks between North Korea and its stated enemies. The current sanctions limit the amount of energy that can be legally exported to North Korea, and Russia would like the tensions to be resolved so they could export more energy (though allegedly they are still trading under the table) and also so that Russia would have an easier path to trade with South Korea.
So to answer your question they are neutral but Russia, similarly to China, is doing its best to unwind tensions while still condemning nuclear tests so that it can resume larger trade with North Korea.
