JFT's dual type data link is not Chinese its Pakistani solution so its not available to BD's J-10s and will Chinese allow you integration of western systems like targetting pod, BVR, ARM, MAWS, ECM etc. Or west will allow BD to give access to their stuff to Chinese engineers for integration, the answer is no, here JFT is superior as it is build on that integration concept and with Mid Air Refueling it will be very potent weapons against BD, because Mayanmar can integrate western systems and standoff weapons like SOW or H-2 for striking inside BD without crossing border, and Pakistan can make sure BD don't get all goodies what J-10 can have from China as Hassina's BD is hostile towards it.
