Given the recent news I think that there is no correlation. Russia and the EU are giving each other the finger and no amount of mutual trade changed Russia's long standing attitude of taking all they can get (of course all global powers do that.) Actually, no trade at all between Russia and the EU would have made that area of the world more stable: the EU won't have to scramble to replace energy providers and no sanction could harm Russia. There would still be a war but nothing else.
