Russian Civil industry after nearly 2 decades of freeze is not competitive in international market and like FSU days they dont have a captive market locally and internationally.
So if Russian aircraft dont size up against global types and are not competitive no one will buy it not even local players.
So the goal now is to buy best what they can internationally and get the best what they can get locally to make their aircraft internationally competitive , at the later stage once the orders keep flowing they can replace the international systems with local one as local industry develops and get enough order to do so.
Unless and Until Russian Civil Aircraft dont have enough orders they wont have a local industry to support it since numbers wont justify it making it locally and it would be cheaper to procure abroad.
