Ukrain is in a civil war between the west and the east. Taking side is a bad idea for Europe.
Europe and Russia are already lost, as the US successfully drove a wedge between the two but finally Russia and the EU have to mop up in Ukraine. Rebuilding that huge country going to overstrech both Russia's and the EU's economy for at least a decade. So the US hit two birds with one stone.
I don't see Europe as being too eager to mop up there. Sadly, it looks as though just like after WWII Soviet Union was rebuilding the ravaged countries of Eastern Europe (like Poland - something that the recipient countries not only avoid showing gratitude for, but desperately try to erase from history) at a detriment to itself, so Russia will now bear the brunt of rebuilding of Ukraine or what's left of it.
Peskov, press secretary for the Presidential Office, already said that Russia will supply gas to Donbass free of charge - it will cost Russia $2 million per day. But he also noted that Kiev's decision to stop gas deliveries to Donbass, leaving people there in the cold, indicates that Kiev actually forfeits its claim over those lands.
Also, all those humanitarian convoys for millions of dollars contained equipment for rebuilding of life support infastructure so eagerly destroyed by the Ukrainians. Russia is already carrying the rebuilding burden.
