Umm... The same company that pioneered widebody twin and FBW in mainstream commercial jets... Sure, once could say the 767 is just a knock off A300 and 777 was a respond to the highly successful A330(TA9/TA11) design, they even copied the FBW!

It's all nonsense.

No doubts the Chinese leap frog everybody in EVs, and developed fantastic high-speed rail/trains system. However, commercial aviation is a completely different ball game, not remotely close in terms of complexity and regulatory requirements. I am not saying COMAC will never succeed, but not within most of our lifetime, and definitely not in the next 20 10 years.

China has been assembling Volkswagen since the 80s, it took them 40 years to start making decent cars to complete with the rest of the world (on a totally different philosophy, EV a lot less complex than ICE cars, and Chinese made ICE cars still absolutely sucked). Their High-speed trains are still largely iterations of designs based on their first generation JV and technology transfer of foreign trains. They don't have the same luxury assembling planes for Airbus.

COMAC on the same timeline is about SAIC in the late 90s making crappy clones of Western design with imported parts and stolen tooling from pervious JVs. ARJ is a knockoff DC-9/MD80 with horrendous economics and dispatch reliability, C919 is their first "domestically designed" plane but all key components are off the shelves western designs that offer zero advantages over A320 and 737, also lack aftermarket support.

Interjet and Cityjet can tell you a thing or two about how fantastic their Sukhoi Superjet were, buying them cheaply is one thing, operating them is not as easy as it sounds on paper.

Competition is great but I'm confident I will not be flying on AC's jet made by COMAC in my lifetime.
