Actually, not quite yet. PPP is not GDP.
The central utility of PPP is that, unlike conventional GDP, it accounts for national differences in the cost of living. For example, men can obtain similar haircuts in both China and the United States; but in China, where labor and rent are lower, haircuts cost much less than they do in the U.S.. Put another way, a man in China can obtain more haircuts with $30 than he could in the U.S. The PPP takes that differential into account and thus tends to present developing countries like China as having more wealth than normal GDP indicates.
In any case, distinguishing between PPP and nominal GDP in comparing the Chinese and American economies will soon be moot: The Economist has projected that in nominal terms China's GDP, buoyed by still-fast annual growth, will surpass that of the United States by 2020.
