China's foreign reserves rose to $2.13 trillion at the end of June despite a trade slump, data showed Wednesday, according to a report of The Associated Press. The reserves, already the world's largest, expanded by 17.8 percent or $186 billion over the first half of the year, the central bank said. It said the increase in June alone was $42 billion _ nearly equal to growth for the full final quarter of last year. China's reserves have ballooned as the central bank buys up dollars generated by its huge trade surplus and influx of investment.
