True, but the examples in these cases are of cities that appeared to have been created anew - in China'a case in the middle of nowhere. India could never afford to create massive new cities using state funds like that, so it's city growth was organic by force, not by choice.

Also the reason these cities are ghosts isn't because there aren't enough people in China (it is after all the world's most populous country), but because they were ill-planned in terms of economic/social benefits for residents.
