I feel we are talking past each other so I will leave it at that.
The specialization you ... expect? is irrelevant.
Business jets are not produced in China, large efficient passenger jets are not produced in China, printed silk scarves branded Hermes, silent diesel electric submarines for export are not produced in China. (See what I did there?) And that's irrelevant to why trade exists.
Even an up-to-the-minute super competitive manufacturer has no incentive (except political and some risk-aversion) to do everything in-house or in one country. It does have incentives to trade with other countries and other companies. Even if it possibly had the machines and low cost employees on hand and already trained to do that, from an economics point of view it should (in the long term), sell some production units, focus on the others and trade for the difference.

Literally every single one of these is false. China is producing every single one of these things.
