China questions the US dollars role in World Economy

The dollar, which was made the reserve currency after World War II, has come under increased pressure of late.

Barack Obama, the US president, cast doubt upon calls by senior Chinese authorities for the creation of a new global currency to replace the dollar as the standard bearer for the world.
