China's foreign exchange reserves had hit 3 trillion US dollars by the end of March. That's an increase of nearly 25 percent year on year. So far, China's foreign reserves remain the world's biggest, nearly triple those of second-place Japan. Analysts attribute the rapid increase to the steady growth of China's economy after the global financial crisis. But an expert from the Central University of Finance says growth may slow in the future. The factors he cites are the control of China's trade surplus and the end of the Quantitative Easing Monetary Policy in foreign countries. Information provided by cctv.com Thank you www.cctv.com http
