China-Pakistan Economic Corridor (CPEC) is being unanimously taken as a window of opportunity in Pakistan But, the routes of CPEC became a debatable topic that which route would be more beneficial for the country. The objective of this study is to find the optimal route of CPEC by comparing eastern route and western routes on a comprehensive framework based on multiple criteria. This decision making framework has been generated from the potential objectives, targets and factors of CPEC. By using secondary data, Multiple Criteria Decision-Making (MCDM) technique has been applied to evaluated the two routes of CPEC. Western route got higher score than eastern route by 0.11 points in aggregate result and it is also better than eastern routes in 25 out of total 38 criteria of the framework. So, Western route is more preferable than eastern route for the construction. Thus the policy implication is that the government of Pakistan tries to focus more on western route than eastern route because it would be more beneficial for Pakistan in term of socio-economic development not only in present but in future too.
