Dumbass, nothing is khairat, Pakistan military is surly paying its fair share for their access to military component of satellite. Pakistan also has GPS and most likely GLONASS too, how do you think Pakistan is dropping JDAMs from F-16s on TTP. On the other hand, India's' friend, Russia, which sanction prone, and would not risk its economy for India, plus Russia is already economically broke and often blackmail India to get money on military project. Meanwhile, China is the richest country in the world and economically very influential. If Pakistan wasn't sure that Chinese would serve them in time of conflict, they would have started their own project. After all it cost only $200 million or so for India, which is lot less than getting 8 F-16s.
It also says, chinese will open one base station in Pakistan in phase two.
