CPEC loan/investment is a honey-trap for Pakistan.  The loan has been given to Pakistan at a very high interest rate along with many other stringent conditions.  They are building coal generated energy plants in Pakistan whereas they are getting out of this source of energy in China because of environmentally damaging effect of it.  Under no circumstances, Pakistan will be able to pay back that loan to China which means Pakistan has to cave in and lease Pakistani territory around CPEC to China on a long term basis.  Pakistan should have learnt this lesson from Sri Lanka, Angola, Malasia, Indonesia where China tried to play the same trick of investing money to upgrade infrastructure in those territories.Unfortunately, that analysis was not done and now they are in the lap of their big brother China for ever
