Something to consider:

--The J10s weren't available for export may be until quite recent bcos of internal PLAAF need

--J10 production might cease soon bcos of new fighters like J20, J31 coming online

-- Has an export version been arranged? Its still a very important component of PLAAF

.........................

Some people were puzzled why the Pak AF didn't buy J10. IF I were them, I also wouldn't. Bcos its stupid for an airforce particularly of the Pak size to operate 2 fighters of similar size and vintage since they already have the F16
