Russia has been reliant on Western aviation for an extended period.

Putin shown ambitions to fully replace all Western Airliners with Russian ones for domestic use. In paper Russian Turbofan development also on tract to support that. PD-8 for Superjet/Regional Jet class, PD-14 for MC-21/Single Aisle Class and PD-35 for IL-96 (double engine version) or C929 Double Aisles Class.
Even with UAC officialy pull out as equal partner from CR929 and thus Chengdu move the project as C929, Russian still involve with the program as supplier partner. China also developing C919 and C929 with both Western variant and Non Western variant. Thus just like with what Russian done now, preparing airliner versions that fully independent from western suppliers.
That move (depend with whom make the projection) has some aviation analysts in the Industry predict potential market of 16% (one sixth) to 25% (one quarter) of global Airliners market that can be attracting to non western airliners (non Airbus and Boeing). This is base mostly on Geopolitical development. Most of them base on Russian and Chinese domestics with potential others come from Central Asia, ME and South/South East Asia and other smaller market in Latin America and Africa.
Off course it is going to take longer time to entice Airlines from Boeing and Airbus, but political movement for some nations to be independent or have options from Western Suppliers especially after Russian Sanctions, is something that some market analysts believe is doable.
Personally for me, it is also depend on how Russian and Chinese can cooperate. Despite China massive development in aero industry, they still need Russia. In sense both of them need each other if they want to give credible challange to Western Manufacturers. COMAC need UAC if want to fight market against Boeing and Airbus.
This is the big "if" so far, as CR929 development so far shown that "ego" still matter as UAC then pull out and decide to work on double engine IL-96. Something that Airbus done with A340 to A330.
