Shanghai assembed MD80/90 and made chunks – inc nose – sent to MDC. Chinese aero industry is now organised as AVIC 1, doing ARJ21 at Xian, and AVIC 2 assembling ERJ135/45 at Harbin. Before all that, mid-90s, Airbus Industrie schemed an RJ with (then name) CATIC. That fell apart on Certification time and money, so the type became A318. Airbus and (AVIC 1/2) have since been seeking a mutually beneficial way of offsetting China’s purchases. There will be intent for AI offtake of some AVIC models – some SAIC MD80s went to TWA. Boeing did explore 737 local assembly, has increased its sourcing from AVIC, and may yet do more. None of this has anything to do with current, transient 350WXB/380 issues.
