Quote me saying Mexico is better, i have never said that, the only thing i said, is China has some flaws in the way to get tech transfers.
Probably you do not know, but China like Mexico are top reciepients of aerospace related investment.
I will ask you, do you think for China recieve investment is not important?
Do you think in China they do not want aerospace related investment?
You just have a fixed view sayng to you China can not get jet engine transfers.
They can, they have allies like Russia, and potential partners like the US wanting to do partnerships with China, in fact i do not think in future years GE, P&W or RR will not do partnerships China in jet engine design.
Because simply aircraf design is getting more and more expensive so it means less and less models will fly.
If you read why embraer did not make a bigger aircraft in the class of C919 or MS-21 or MRJ o CS100, is smply because they market they say is not so big, so some losers will come between those programs, so Brazil decided to just re-engine the E-190 family
So the aerospace related chain supply business will boom and of course many nations will follow Mexico or China in that regard.
If you want investment and a share of the market, every nation will be forced to cooperate, they already do it, simple look at B-787 or A-350 or Embraer aircraft.
And even if you do not like it J-10, J-11 or J-31 all these aircraft have parts developed in different parts too
