Chinese leaders can allocate whatever money they want to a project. They can order their citizens, in mass, to move away from an area. They can ignore labour rights and force workers to work in hostile conditions. They can ignore their own laws, or quickly change it when they want, if it impedes some project they have deemed important. They can ignore any ecological concerns. And so on ... India and the USA cannot do all this, because of the constraints their democratic system places on their governing leaders.
This is why Rahul Gandhi (India's current opposition leader) says that the biggest challenge that both the US and India face today is to figure out how to revive domestic manufacturing without sacrificing our democratic values.
