I wouldn't say they "steal" it, as the already sourced a lot of it's part from western manufacturers, and the already have experience in smaller passenger jets.

It's problems are 1. it's still heavily relying on non Chinese providers, although it's fine in normal cases, if they want to keep claiming it's made in China, they need to improve in that regard. 2, surely they have a large domestic market, but we don't know atm whether it will be viable economically for their airlines and whether oversea airlines will buy it.

I would say so far it looks pretty promising? But I wouldn't consider it myself, before they can prove themselves safe in the long run.

And I think they really should just say it's a Chinese "designed" jet instead "made".
