IMF: China's 2011 nominal GDP is $7 trillion

The latest IMF estimate for China's 2011 nominal GDP is $7 trillion. Most of the economic data for this year have been collected and the late-year estimates are always very accurate. Only four more years to go before China's economy exceeds $10 trillion in 2015.
The above IMF estimates doesn't take into account the changing exchange rates of the 2 currencies. Adding the estimated yearly Yuan appreciation against the US dollar would make a very different outcome from that of the estimation above.
You are correct, but IMF numbers are easier for lay people to understand.
A few years ago, the IMF changed the way it calculated GDP. To smooth out currency fluctuations, the IMF switched to the average currency exchange rate for the entire year; instead of using the traditional currency exchange rate at the end of the year.
It is more appropriate to use the end-of-the-year currency rate for China, because its currency keeps appreciating. It doesn't make sense to use the average currency exchange rate for the year, because it will only reflect half of the currency appreciation and undercount China's economy by a quarter of a trillion.
However, I don't want to confuse lay people and it's easier to just use the IMF numbers. An estimate of $7.25 trillion is closer to China's actual GDP, but it's too complicated to have to explain it to non-economists.

Also, the United States is the largest contributor and has the largest percentage of votes at the IMF. The IMF tends to inflate projections for the U.S. economy (e.g. IMF 2011 projection of U.S. 4% economic growth is silly; it's actually 0.85% for the first half-year of 2011) to keep its largest shareholder happy.
Unlike the IMF claim, the U.S. economy will not hit $15.2 trillion this year. $14.6 trillion x 1.04 = $15.2 trillion. There is no way the U.S. economy can attain 4% growth for this year. Using real economic data of 0.85% growth for the first half-year, a closer estimate is $14.6 trillion x 1.0085 = $14.7 trillion.
From U.S. Department of Commerce, Bureau of Economic Analysis:
"Real gross domestic product -- the output of goods and services produced by labor and property
located in the United States -- increased at an
annual rate of 1.3 percent in the second quarter of 2011, (that is, from the first quarter to the second quarter), according to the "third" estimate released by the Bureau of Economic Analysis.
In the first quarter, real GDP increased 0.4 percent."
Math:
U.S. economic growth for first two quarters of 2011: 0.4%, 1.3%
Average U.S. growth rate for first half-year of 2011: (0.4 + 1.3)/2= 1.7/2 = 0.85% (not 4% like the IMF is claiming)
