Treasury Secretary Timothy Geithner urged Brazilian officials on Monday to lobby China to let its currency appreciate, a Brazilian official with direct knowledge of the discussions told Reuters.

In a meeting with Brazilian Finance Minister Guido Mantega, Geithner argued that the undervalued yuan is just as much as a problem for Brazil as it is for the United States, and urged Brazil to lobby the Chinese to correct that situation, the source said on condition of anonymity.

Mantega replied: We're against manipulating exchange rates, the source added.
