I am sure Chinese AWACS can make a difference but that will invite severe sanctions. it wont impact any of Russian defense industry. its myth that Russia does not want to import stuff that most likely disposable like drones, rockets and shells.However, selling fully assembled weapons would negatively affect Russian defense industries; not exactly a Win-Win scenario.
Russia is working on how to remove those 1300 Airbus/Boeing/Bombardier/Embraer from its fleet and than you add large Civilian chopper fleet expansion. see the 5,000 engine order in air transport context up to year 2030. and this does not include replacing engines on those 250 SSJ as they are trying to built parts to operate it. this is scale of effort needed to be independent of West.
The program for the development of the air transport industry poses a large number of tasks for us. Until 2030, Rostec enterprises must supply the country with more than 500 aircraft, at least 750 helicopters, and almost 5,000 aircraft engines.
