World bank head sees dollar's role diminishing

According to the president of World Bank, the dollar now is losing its unchallenged economic super power gradually. On the other hand, the Euro and the Chinese Renminbi are replacing the position of dollars. In addiiton, Mr. Zoellick, who previously served as the United States trade representative and as deputy secretary of state thinks that Euro's acceptability will grow becuase it offered a respectable alternative for financing international transaction. For Chinese Renminbi, even if the president of China decided to decrease the use of Renminbi in the international transaction, many experts still think that it will envolve into a force in financial market. Furthermore, because of the decrease of using Renminbi in the international transaction, the China government can control the exchange rate easily. It will help Renminbi to gain predominance in the financial market. As we know, dollars has been the most common currency over the world for a long time. However, now the dollars will face the challenge from the euro and Chinese Renminbi. the US government should think find out some methods to face.
