An aircraft is only as good as the support network for parts for it. Boeing, Airbus, Embraer, etc have all spent years building this support network. Every new maker faces this challenge. Sukhoi found supporting their aircraft sales outside of Russia and bordering nations hard, which hurt their sales and service reliability. A multimillion dollar aircraft can literally be made into an expensive paperweight by a tiny screw if that screw cannot be sent to the aircraft maintenance team overnight.
I don't no why ppl don't believe in Chinese aircraft yet the aircraft use same Western engine use in similar western aircraft
