How can you say China is devaluing its currency to boost when the price of the currency is increasing in dollar terms? And generally speaking you can't keep exports inflated for long by currency devaluation any more than you can use inflation to keep unemployment low. In the end the trade balance will revert to what you'd expect from the savings rates of the two countries, and in this case China's higher savings rate means it exports a lot more to the US than vice versa.
