I completely understand your concerns, very genuine. However as you know yourself CPEC is flagship project of OBAR, China would make it this project a role model in order to further project itself globally . China's failure in CPEC would mean a major dent in Chinese economy, investment, security and geopolitical importance. CPEC is something that Chinese will make a role model, it would be a show case model for the entire world. If things were left for the Pakistanis , they would have messed it up as already. You can sense an urgency in completing so many projects with zero controversy , just goes to show you how serious Chinese are here. If CPEC becomes a success, China would be benefiting the most. Also Pakistan is too big and too strong to be colonized by corporations, state institutions are functioning independently, far better than most countries. In recent times Pakistan has seen the worst, no country has done better on ground than Pakistan in defeating terrorism, Pakistanis are very resilient , not so disciplined though, something they can learn from Chinese counterparts. I sincerely believe that CPEC would do the same to Pakistan's economy as Nuclear arsenal did to defense of the country.
Having said that indian propaganda would continue to get louder as the project picks up the speed. This needs to be tackled on all forums by Pakistanis and their well wishers.
Its 80,000 acre. Pakistan is not a small country by any means.
