Had pointed out that CPEC projects were overpriced back in 2016-17 on PDF. Had even provided links for equivalent projects elsewhere for comparison. I even pointed out that it will be cheaper to simply take commercial loans and use Pakistani companies to build the power plants by themselves.
Someone from the grass is greener side even argued that since projects were funded by loans, the power projects are more expensive, which was quite funny.
Let's not forget that a lot of powerplants are actually second hand, but come with guaranteed profits requirement.
