Massive difference between airliners and aircraft. Russia has not shown itself capable of mass manufacturing airliners. (Or even advanced aircraft for that matter.)
That said, as a petro state, they’re fine running inefficient engines across their skies.
Now look at them post sanctions.
The SSJ-100 contains far more important systems (not parts) [1] than e.g. Embraer’s regional jets. It was designed with consultation from Boeing, including throughout manufacturing. Russia’s indigenous jets are terrible, and there is no reason to expect them to improve, they can’t compete against the Chinese for the anti-Western market.
To be fair to Sukhoi, this is how Boeing builds planes. If America were sanctioned by its allies, I’d similarly argue that Boeing, too, is incapable of mass manufacturing airliners.

Embraer jets all use Pratt & Whitney engines which is the hardest part to replace.

All Chinese jet airplanes use Western engines and other systems[0][1]. China can't sell them on the anti-Western market just like Russia wasn't allowed to sell Tu-204SM with PS-90A2 engines co-developed with Pratt & Whitney[2].

Yes, of course. The version of SSJ-100 with Russian-made engines and other systems is called SJ-100.

We have been hearing this never-ending story of "aircraft will be available in 2 years" for a very long time. :)
