At least it wasn't too ridiculous but Aryan Argwal hasn't got an effing clue. He has no idea what "the government" really thinks. No one does except them. They don't broadcast that stuff like little bitches and they sure as hell don't tell foreign "experts" what their plans are.
Airplanes don't support that many people so it wasn't a big priority. And they needed to spend some of the dollars they make or it'd look really really bad one-sided. What else can they buy from the US ? (chicken feet, I know) And there's two manufacturers, one in Europe and one in the US so they could bounce them off each other. It just wasn't a big priority.
Now, however, with the chips thing and Mr Biden's and Mr Trump's antagonistic attitudes, and all the propaganda and lies (there are NOT thousands of people dying in hospitals, I can put up photos, it's one giant stupid lie) ... anyway, it's becoming obvious that at least for the near future China has to look out more for itself. Hence, bigger emphasis on making their own planes, at least for domestic use. Maybe end up selling some to Russia and Iran and other places the US has tried to embargo. I can't see them wanting to compete with Boeing and Airbus internationally. There's no reason to.
^ Air China doesn't have one of the world's best safety records because they have "shoddy crews". Get real.
