I think i should clear some air regarding the assumed limitations in procurement of fighter jets by PAF in the wake of this economic situation. Firstly, it's not going to be all messy forever, our economy is already picking up the momentum, it's on the right track. It's likely that we'll be able to afford advance equipment for PAF in a matter of few years. Secondly, Chinese are our brothers, they've had our back and assisted us unconditionally regardless of the prevailing economic or political situation in Pakistan. Such is the nature of China-Pakistan relations. I'm sure they'll make an arrangement by which it'll be easier for us to pay like installments, soft loans etc.
Yes you're right it's not a vegetable market where one is free to pick whatever he wants but given the special nature of China-Pak relations, it's not only possible but also highly likely that Pakistan will have "wide-range" of choices in this regard.
