In terms of purchasing power, China's GDP is projected to surpass that of the Eurozone in a year or so, according to a new report by the Organisation for Economic Co-operation and Development (OECD). It should become the world's largest economic power by 2016, overtaking the U.S. Even more strikingly, based on current trends, by 2060, China's GDP per capita will be 25 percent higher than the current GDP per capita in the U.S. As for India, its GDP will exceed that of Japan in one or two years' time. Together, the combined GDP of China and India will be higher than the combined GDP of the seven major economies, or the so-called G7 group of countries, by 2025. Two years ago, it was estimated by the OECD at less than one-half of the G7's GDP.
