The text of the joint statement signed by Putin, Aliyev, and Pashinyan. Mostly on resuming severed transportation & communication links. Separately Pashinyan says that the issue of the status of Karabakh and Armenian POWs remains unresolved, unsurprisingly http://kremlin.ru/supplement/5606
Looking so far at statements coming from Putin, especially on economic developments which will potentially usher in stability and long term peace, it is not at all far fetched to think that Putin in most likelihood sees the conflict not in the same vain as Crimea but as Chechnya.
He is not inclined to see this as Armenians righting a historical wrong, but as Azerbaijan trying to keep within its borders a recalcitrant ethno-religious minority. Therefore throwing money at the region, infrastructure development, de-blocking transportation, etc
will have the same pacifying effect as it has on Chechnya. Also it should be noted, the whole thing is not original to Putin. This has been the Soviet cum Russian line since the origins of the conflict in 1988. CPSU and Gorbachev pushed the same line with little success
So we will have to live and see what comes out of this. Today is Monday, and on Mondays I am notoriously mirthless and skeptical
