"Since our last assessment in the summer of 2011, the RMB has certainly appreciated," noted IMF spokesman William Murray in an interview with the Wall Street Journal.
"However this information alone does not permit us to offer a new judgement on is valuation. We have more analysis to do," he said.
According to IMF data, China's exchange rate has been allowed to rise faster in the last year as compared to the past. The Yuan’s real effective exchange rate, based against a basket of currencies and accounting for inflation, went up by almost 20 percent in the last three months on an annual basis, and by over 8 percent throughout 2011.
But, the US remains unimpressed. Speaking to the World Economic Forum on Friday, US Treasury Secretary Timothy Geithner asserted that the Yuan was "still below almost all measures of fundamentals."
"China does represent a really unique and formidable challenge to the global trading system," said Geithner at Davos, as cited by AFP.

Chinese authorities though have dismissed Geithner’s statements, claiming that, “people in the international community even don't know the latest figures and their minds are filled with the old figures about China's trade surplus."
"During the last few months of 2011, many Chinese private investors started to spend the Chinese currency buying US dollars, which is an indication that the currency is near an equilibrium level," added Li, who expects China’s trade surplus to further decline in 2012, due to the stronger Chinese currency.
Eswar Prasad, a Cornell University economist and a former senior IMF China expert, also backed up Li’s claims, noting that the Yuan’s effective value, adjusted for inflation, had climbed by around 25 percent since 2007.
