I am not an economist, but to me arguments 1,2 and therefore 5 seem specious. 3 and 4 hold water, but they are pretty self explanatory.
China's economy, to me, seems like a leverage play on the US. If the US economy seriously stagnates, China's economy will follow suit, and likely in a much more dramatic fashion. The opposite is also true, when the US consumers get to spending China (at least for now) stands to benefit tremendously.
For me, the best option if you are looking at foreign currencies, is to go buy a brazilian government bond and get 10% on your money in 3-5 years.
