Chinese weapons on the back of soft Chinese loans from china EXIM bank.
western weapons from own sovereign funds.
item 2,6,7 are not confirmed.
Item 6 can be considered confirmed. Item 6 would mean if no SU-35, then it would have J-11D's as the need has been recognized. I've written about it. Pakistan now needs to create a strengthening Navy to ensure countries using Gawader that Pakistan will protect their trading through the port.
Over the next 5-7 years, Pakistan will start to become a regional power shortly after the CPEC starts working. You'll see serious increases in PAF and PN's fleet (and Army will remain on the current strength). Its PAF and PN's time as they need to project power all the way to 400+ nautical miles due to Pakistan's extended EEZ and Gawader having seriously heavy trade requirements.
Pakistan isn't as cheap and weak as you guys still think. It's now the top 25th economy. Plus, just in expanded tax base and money recovered, over a couple of billion dollars have been recovered and the savings account is around $ 20 billion (not talking about reserves in Gold, Euro's and Dollars).
Just by plea-bargain deals to recover money from bureaucrat and political thieves, your country has smartly gotten back over a couple of billion dollars from different politicians who know they are about to get screwed and they came in and paid 100% of the money so they don't get to go to the jail. 85% of these guys were from Zardari's party. Remainder from Altaf, Ruling and IK's party.
So Pakistan can readily pay a couple of billions for any deal in cash if need be. Chinese equipment comes from Chinese financing.Russia for their deals will be offered cash. US stuff also comes from their own financing as the interest than helps run the American economy and creates more jobs and all.
This is how important it is for everyone to pay taxes, your country will only create more opportunity for you, won't need loans and will grow economically and defense wise. If everyone in Pakistan paid close to the real amount of taxes, your country would pay off all of her debt in less than a decade and would never need WB, IMF or ADB loans for Dam, Electric or any project, within three years of establishing the real tax base.
