Jokes aside, I think the biggest problems are:Why should they and even if there some hype oven this ag the PDF, so for no-one was able to give a reasonable explanation for this rumour?
Pakistan gas no carrier and if China would break the non-export obligations, the J-16 would make much more sense.
Therefore IMO this is pure nonsense ... even more since the PLAN is not building only 24 gor its own use and then restart production for Pakistan.
1. Does Pakistan really have a need for J-15 and the Liaoning (or the Shandong).
2. Even If Pakistan has a need for these, can it economically afford to operate and maintain an AC like the Liaoning and/or the Shandong.
3. Even if Pakistan have a need and can afford to get the Liaoning and/or Shandong, is it really money and resources well spent? Couldn't Pakistan spend the money elsewhere to fulfill its need and get bang for the buck.
