I look at this differently. They are forced to pay (ostensibly) higher prices because they lack the ability to provide security for their investments. Relying on incumbent governments to guarantee security on large capital project assets in jurisdictions where expropriation is seen as a national pastime is an extremely risky strategy.
So perhaps there is something more insidious occurring. I am carefully watching the political strings attached to these investments and whether or not the Chinese wish to export their political model in addition to their goods...especially if China seeks to emulate its own model for suppressing non party members.
