What I ment was , let me make it simple for understanding.
Let's say my neighbour's need a path through my land (China wanted an alternate path) ,the neighbour comes to me and says I want a path through your land.if he tell me that he will spend the money needed and I have to pay later,I would tell him to go F**k himself. But that was not what happened in cpec case. Chinese were given guarantees on assured returns(Pakistan could have negotiated cost sharing).
After the project started , china awarded the contracts to Chinese companies , material needed purchased from chinese companies ,Chinese labour worked on it mostly on important roles.what ever the billions of dollars paksitan talks about did not really enter pakistan economy(otherwise Pakistan would not be struggling for dollars every year, Chinese paid in their local currency and Pakistan has to pay back in dollars).
