China moving away from US currency implies they don't want to trade with us - unlikely. But if they did do this, they'd sell the currency on the global market, the cost of the dollar would go down, and US exports would likely boom due to increased competitiveness. In other words, it remains in China's interests to keep their US reserves. And in everyone's interest -- as far as the numbers show, the safest asset on earth (as crazy as it sounds) is US government debt.
China does not own that much American debt, and has not been accumulating in the past few years. They have maybe 1.2 trillion out of the 15 trillion: http://en.m.wikipedia.org/wiki/National_debt_of_the_United_S...
