So it is safe to assume that when Chinese source say that there are not interested in CHANGING the route and have agreed to one route and will stick to it, they are referring to the first one.
The media have created such confusion that for many people in public, the second option is the original one and it is PTI and IK who want to get that altered, there are some confusions and many more are being created by hater and supporters of both political parties. It is a shame that a project of such importance is being politicized.
Tu Summarize, it is the first route, as below that is the original one and it is this one that the Chinese have said they are not willing to change.
Personally i think this is the best possible route, in fact, the only option that makes sense. Away from border, providing an alternate route across Pakistan and passing through under developed area with huge potential of growth.
