It's a long way from building stuff of someone else's blueprint to designing a turbine twin from scratch. Also don't Boeing and Airbus seem to have repeated quality control issues with some of these 3rd party vendors?really?
The same company that builds the Y12 has built under license several western aircraft like the ERJ145/Legacy (for the Asian market) and all sort of Eurocopters.
They also make a lot of parts for Boeing and Airbus, the A320 elevators and rudders are made there, they build about 5% of the airframe components of the new A350....and for Boeing they make components for the 777 empanage.
