They haven't even cracked the automobile market yet. No one in the west will buy a Chinese car, let alone a Chinese plane.
Everything I've heard about them is that they're unreliable and unsafe to an extreme degree. You're apparently better off buying a 3 year old Toyota Hilux or Nissan Navara for the same price as a brand new Chinese truck.
Also, mitsubishi can build rockets similar to anything spacex can put up.
Both are Japanese companies in the American version of ownership.
In the proximity version of ownership, both are pirate flags.
China would have very little reason to enter the broken US car market.
Especially when there is an island sitting right there that is close enough for them to buy their own Mitsubishi 787s
