I'm admittedly very much not an expert in this area. But my post is less about the C919 specifically, and more about China's track record of developing manufacturing processes very rapidly such that they compete on the world market. Specifically I'm thinking of how China is suddenly exporting tons of EVs throughout the world at prices that USA/EU auto-makers can't really compete with. Over 50% of EVs sold in the world are Chinese (and none of those cars are allowed in the USA).
If China decides they want to continue developing and building commercial airplanes, where will they be in 5-10 years? Where will Boeing be?
