China’s foreign-exchange reserves topped 2 trillion USD for the first time, strengthening the nation’s finances as the government boosts spending and cuts interest rates to counter the financial crisis. National Bureau of Statistics chief economist Yao Jingyuan cited the increase at a forum in Beijing on Thursday, without giving an exact number. Trade surpluses helped to swell the reserves to 1.9 trillion USD at the end of September, according to the central bank.
