"China is an economic giant, but its money is still a bit of a runt. Unlike the dollar, euro and yen, it's little used away from home. The No. 1 exporter has kept its currency off world markets and restricted buying and selling...Now it has reason to loosen the grip on the renminbi, which means 'the people's currency,' and is better known by the name for its biggest unit, called yuan.
