which we paid for...
you seem to forget that part...
i love how when we talk of china we tend to wash their hands of the dirty game they played.
Yes, the roads China built, with Chinese labour flown in from China, with the equipment flown in from China, paid for by interest applied loans from the Chinese- which come out of Pakistan's coffers.
So actually, even the Chinese get free rides, just like the Americans, or Brits, Germans, or [insert whatever country here].
Chinese built roads, built by Chinese workers, in a country with a 6+% unemployment rate, the Chinese firms could not find local workers, thus had to import their own at exorbitant rates, backed by Chinese loans, serviced from Pakistani coffers.
