For obvious reasons, Russia would not publish its official strategy or military doctrine for Turkey. Yet, there are some semi-official publications on the matter,of which I included a few below(in Russian language). Basic Russian outlook on Turkey has not changed from Soviet times, i.e. Russia and Turkey are potential adversaries . Reasons for that are multiple:
- Turkey is still member of NATO (an inherently anti-Russian organization)
- Russia and Turkey have very different ethnic and cultural backgrounds
- Turkey controls entrance to Black Sea which is vital to Russia
- Russia and Turkey have different interests in Middle East (Syria above all)
- Russia and Turkey are historical adversaries.
Still, recently Russia has gone out of its way to appease Turkey, despite heavy Turkish provocations like shooting down Russian Su-24 over Syria, killing of Russian ambassador in Ankara, practically invading Syria (Russian ally) and arming groups that fight both against the Syrian government(Russia endorsed belligerent) and Russian troops in Syria. This is purely pragmatical for the Russian side - Russia already has lots of enemies including Turkey, not rising diplomatic tensions with them could only be seen as beneficial.
It is worth mentioning that Erdogan (Turkish president) with his nationalistic and moderate Islamic views represent a wild card in relations with the Western globe of influence(that is seen as the de facto "enemy" of Russia historically). In fact, there were even rumors that the recent military coup attempt against him was silently endorsed by the US, and that Moscow helped him by warning him a few days ahead. If this is even partially true, Russia could count on political goodwill with Turkey while he stays in power.
