The Pakistan Air Forces experience with the Shenyang J-6 wasn't a success. Rolls Royce were called in to adjust some of the imperial to metric measurements on the engine components in China to save the Chinese loss of face over the frequency of engine problems. It is well known in Pakistan the details of the 're-education' of Muslims in the north west of China so I do not think that they would be that pally in the military and religious sense.
