UNITED NATIONS, Sept 23 (Reuters) - French President Nicolas Sarkozy said on Wednesday the world had grown too complex to rely on an economic system based on one single currency.
"We cannot have a multipolar world and a single currency," Sarkozy said in a speech to the United Nations.
It was not immediately clear if Sarkozy was referring to the U.S. dollar or to plans under discussion to support the International Monetary Fund's Special Drawing Rights (SDR) as an alternative reserve currency.
