You cannot question CPEC in Pakistan, if you ask for even a little detail about CPEC project you will be tagged as an anti-national. They can't even question their government regarding the number of employment generated by the project and the share given to the Pakistani citizen, most of the projects under CPEC are built in Punjab province and other provinces are fighting to get the better share.
There are only two beneficiary of the whole CPEC program, one is definitely China and another one is Nawaz bhai and his political party.
