China will have a secondary issue down the road, pre-2020 thousands of domestic cadets were going to Australia, America and Europe.
That has completely stopped. Domestic training is rising but still can't support the supply. I've trained many in Australia over years until covid ended that, and still stay in contact with a few of the good ones. They tell me that a massive number of those assigned to widebodies are now back doing 320/737 ratings. Initial type rating training for cadets has almost dropped by 75% at one of the major Chinese Airlines I was told because the last of the cadets they sent overseas (including Australia) returned in Jan this year.
