Building the infrastructure for CPEC is the easy part. Effectively running it will be more difficult. How much will Chinese companies charge for the electricity of all those power plants ? How will Chinese enterprises running these plants deal with the issue of electricity theft in Pakistan ? And then there is the issue of security of the whole enterprise. The development of Gwadar will be interesting. As of this moment there isn't even a proper road going from the port out of the city. Trucks going to and from the port have to drive through the market place of Gwadar. Its narrow and congested. The "Gwadar land grab" by the people isn't helping the situation either. They hope to buy land now on the cheap and sell it later at a higher price for development.
Your questions give the perception that seems you are not following this thread....
FYI...CEPC security is Pakistan Army's responsibility & being directly handled by them (arresting of Indian RAW spy & restoring the peace in the region was the big achievement). While OTOH bringing the several thousand of innocent people who were mislead by Indian back extremists to the main stream (review some of the videos shared earlier on the same thread).
Work on different highways are on the move on a rapid pace & within next 6-12 months majority highways will be online & interlinked.
Chinese IPP's are coming on public private sector & responsible of their own business interests. The power loss was not due theft but its a loss from transmission lines which are under heavy renovation under CEPC.
Hope above will clarify your concerns... & suggests review previous pages to better understand....
