Beijing: China's foreign exchange reserves rose to $3.3387 trillion at the end of last September, an increase of $16.5 billion, or 0.5%, from August. According to Yemen News Agency, the Xinhua News Agency quoted the China State Administration of Foreign Exchange as saying that the increase was due to the combined impact of currency exchange rates and changes in asset prices.
