China didn't go to the trouble of setting up an offiicial exchange rate between the Yuan and the Ruble for nothing.

China Maneuvers To Take Away U.S.' Dominant Reserve Currency Status.

It should go without saying that China and Russia have designs to end the U.S. Dollar hegemony and debtism free ride. This is fundamental to understand and will be a game changer. The impacts on the standard of living of these players will be profound and especially negative for the U.S. How and in what manner this plays out is the question. I strongly believe that the answer lies in two parts: letting the U.S. put a noose around its own neck and then at the appropriate time, kicking the chair out from under it.

The first part of the operation is now advanced and is described below. The second part involves China and Russia preparing their relative currencies to be accepted in lieu of dollars. It means making the yuan and ruble at least equal to, if not superior to, American dollars in world trade. As you can imagine, the U.S. -- a country with a debt-to-GDP ratio approaching 110% -- can ill afford this sort of challenge to its status as a reserve currency.

China has already advanced the Yuan as a principal exchange currency by incorporating a series of deal with other countries. Such arrangements are hardly mentioned by U.S. financial media, but they are going on constantly. So far, the People's Bank of China (PBOC) has signed nearly 2 trillion yuan worth of currency-swap deals with 20 countries and regions, including Hong Kong. Here's a breakdown of happenings:
