I'll give you a few pointers.
1, JF-17 is a Sino-Pakistani cooperation program. Neither China nor Pakistan has the right to sell JF-17 alone before the other agrees.
2, CAC only has the R&D system for JF-17, not the production line for JF-17. The R&D system does make it, but the number of products made with the R&D system is very low and very costly. They only make samples for use in test-type products and mass-production types. They cannot be used to manufacture mass production type products.
3, Sources indicate that the Myanmar Air Force's JF-17 had major problems before the mission and it was Pakistani technicians who secretly flew to Myanmar to fix the problem. ------ The people who went to fix the problem were Pakistan, not China.
You can judge your point again.
