Pakistan should look into the JH-7 which is also considered a deep strike platform, something PAF/PN needs desperately to hold off the Indian Air Force while also freeing up some core PAF Dedicated aircraft such as the upcoming JF-17 Block III. however what China needs to do is increase, better the opportunity of sales , such as adding technology, weaponry to aircraft needed and or wanted by said customer. J-15 is a good strike platform, but in my own opinion, the jet sometimes get overrated or underrated, not moderately/investigated into what the potential of it could be.
