The chinese economy is on a slow and steady rise. Economist's predict that they could have the number one economy in 10-15 years at this rate. They also just surpassed Japan, to become the world's second largest economy.

on the story if you are interested in reading it.
sorry for the slight /derail lol.
Contributing with the derail, the current value of the currency is hardly and indication of the economy as it is that value's stability, and yet that it's only one of many important aspects.
Chinese economy is steady increasing but fighting against another powerful detriment, they are getting old, the part of their population who manage the economy was been restricted to the "One-child" policy for a couple of decades now, resulting in a national average increasing a few months every year, which is an alarming condition that will result in consequences not only for the economy but the Chinese society itself.
Moreover with the development of the nation the population itself is getting richer, which means, between other things, a larger need for natural resources to provide what the people can now purchase with their money, returning large winnings for those who can provide said commodities, being this a person, a company or an entire nation, growing at the same time, and even better rates, as Chinese economy does.
Unfortunately while this may sound promising and full of opportunities, Chinese people still conform more than 1/6 of the global population and the question "will our resources suffice to transform 1 of each 6 persons from farmers in blue/white collars?" is still unanswered, although either way he who control the resources will have the upper hand in the world's economy for the years to come.
Sorry for the long derailing post, I thought it could be an interesting reading.
