There is a lot of activity going on in development. Either you are misinformed or don't have too much insight into Pakistan. 3 years from today, Pakistan will start to grow rapidly (unless a war or serious terrorism breaks out). They are cleaning up their country without mercy. The goal is, like the UK, (but it'll take time to implement), that the weapons only belong to the law enforcements, not to terrorists or gangsters. This chapter of decades is being closed and the militancy, violence and all is being dismantled.
At the SAME time, there are over $ 50 billion worth of projects going on across Pakistan. I don't know who told you there was no time for development. There are a couple of threads on here which show you status on certain infrastructure projects and with pictures. Check that out so you can come up to speed
This should be the case. Otherwise, they should just get used -16's in numbers, ready to go and increase strength, instead of going for J-10B. With this, numbers are increased right away, and they can focus on J-31 / 5th gen, with more modern JFT.
But if they are wanting J-11B, I've always said it, that was the need of the hour, twin engines, about 4-5 squadrons (2 for dedicated naval support, with 2 dedicated JFT naval support squadrons), the rest 2-3 J-11 squadrons for the PAF, supplemented by AWACS, would be a great force multiplier asset.
