"China's economy will overtake that of the United States by 2035 and be twice its size by midcentury, a study released Tuesday by a US research organization concluded."
"The report by economist Albert Keidel of the Carnegie Endowment for International Peace said China's rapid growth is driven by domestic demand more than exports, which will be sustainable over the coming decades."
"Keidel, who has worked as a World Bank economist and US Treasury official, said the rise of China to the world's biggest economy will happen regardless of the method of calculation."
