Industrialization should be in Southern Balochistan, due to lack of employment oppurtunities in that locality. Punjab is already having High Human Development Index, while Balochistan, Southern Sindh & FATA still having the worst Human Development Index in Pakistan.
Why China is establishing the CPEC, mainly because to uplift the Western China equal to the rich Eastern China. See what West Germany did about East Germany after the Fall of Berlin Wall and merger between East & West Germany. So I think our main focus of Industrialization should be Balochista, FATA & Southern Sindh, it will help to provide employment to the locals and the Higher Management / experienced staff can go their from Karachi & Punjab.
Having development in already developed areas will certainly not help Pakistan improve its overall Human Development Index as Northern Punjab, Central Punjab & Karachi are already having the Highest Human Development within Pakistan.
I'm saying this because RAW easily exploits the unemployment of the Southern Balochistan to use it for them. Once of the local separatist leader of BLA BLF said in a press conference during the surrender ceremony that there is no source of income for the 250,000 household families in Southern Balochistan. BLA BLF BRA pays them 25 to 35 thousand per terrorists. Its also the report of ISI MI. We must not leave any loop whole for the RAW CIA to avail it for their own motives.
