i think you had way too much coffee this morning. pakistan is in negations for the hq-9 and hq-16. yes thats true.
but china giving you the j20? i think you need a stronger coffee to get you into reality. the j20 is built specifically for plaaf and is banned from being exported.
the su-35 is fake news to push india to go Russian and buy the su-35, or they will lose it to Pakistan. Pakistan cant afford it. 24 jest will cost you $2billion ($85 million each) they still need $1.4 for the 36 fc-20's their ordered.
and now the armed forces is prioritising the budget towards the navy. as the air force got a large bulk of the budget for quiet some time. now they realised that the navy needs help. and is being helped.
and please don't say you have friends in the armed forced who tell you. or you have "sources" because you probably do, but its false. i dont buy the idea someone is telling you what the armed forces is procuring or what they are doing.
Pakistan first to China's table for HQ-9, HQ-16 missile systems|WCT
i will contact the Pakistani consulate in London and notify them that some wanna be leaker is revealing information about the armed forces of Pakistan on the internet. then you will find out what happens.
