The only friend Pakistan has left is China. Now dont screw this friendship up. Pakistan is already isolated in the world, how much more isolated you want Pakistan to get.
Let China use Gwadar to transport its resources to its western provinces. The more work happens in Gwadar, the better for Pakistan. There is no point building a port and letting it rust under the hot sun like its doing now. Then why build the port in the first place.
If Pakistanis really think like you, then I think Pakistan doesn't deserve a friend like China. Go ahead be isolated from the world and the region, if thats what you want. As of today, all our neighbours, except China, hate us. As of today, all countries on eartth, except China, look down at us.
