Here's anothe byte for you of Pakistan. China practically owns Pakistan as they invested tons of money into Pakistan infrastructure! New corridors to/for to China, new Habors, etc. Tell me how China not own the Pak's. I read a lot of Pak's people are furious with their Gov. decision with the Chinese infrastructure deals. Just imagine whatever goods the Pak's manufactured will be ousted like how China took away America's manufacturing and it's jobs. China ain't dumb, they know the way of how it works. With trade wealth they will be the Giant of the Worlds giants in time.
I'd like to believe China had a hand in the releasing of the captors. Could the Pak's be realizing 
 it's that trade Rules! like China understands today? Play ball with one and all for your wealth!
