| Here's my simplified way of thinking about it: The Chinese government wants its citizens to be relatively poor. Why? because then it can use them as cheap labor that is a valuable tool to leverage on the world stage. Plus, poverty stifles political activism. How does it keep its people poor? Well, by making sure a USD spent in China can buy 4x as much rice/milk/chicken/etc in China as it can in the US. This will mean income of Chinese workers and merchants will also remain low. How does it do this? By keeping the value of the yuan low, by direct manipulation of the currency, which it pays for by a high import tariff. (Which, again, makes Chinese people poorer by making things coming from outside the country very expensive.) By using this strategy, the Chinese government uses its people as underpriced laborers that give it a huge export surplus and which it can use to influence world events, as well as to generate vast government capital (essentially capital it is withholding from its citizens) it can use to invest in foreign companies/governments. (Of course now the picture is muddying somewhat because the extreme GDP growth is making many Chinese wealthy anyway, despite all these obstacles.) |
In addition, the large amount of foreign debt holdings gives them a claim on future output (or land, or other capital) of other countries. That gives the county geopolitical strength.
