future of ukrainian air force?

Now that Yaku boy escaped the country and the rebel alliance storming the capital buildings, relations with Russia probably go down hill.
Antonov will probably be hit hard. no more An-70 cooperation or An-158s being purchased and a slant towards the west.
will we expect a mass retirement of Soviet era types and a gradual incorporation of western types?
does China potentially have a role to fill the vacuum as Ukraine’s links with China are strong (Ukraine did teach the Chinese how to build tank engines, carriers, and the su-33)
