China to be largest economy in 1 to 2 decades: economist

BEIJING - China will surpass the United States as the largest economy in one to two decades, predicted a Chinese economist at a world economic congress Wednesday in Beijing.

Qian Yingyi, a well-known economist in China and dean of the School of Economics and Management (SEM) of Tsinghua University, said China would become the world's largest economy "almost surely before 2020 in terms of purchasing power parity (PPP)."
