China's foreign exchange reserves jumped by 153 billion dollars in the second quarter of this year to the equivalent of 3.2 trillion dollars, the central bank said on Tuesday, according to dpa. Total reserves were up 30 per cent year-on-year at the end of June, the People's Bank of China reported. The bank said new lending by commercial banks rose to 634 billion yuan (98 billion dollars) last month from 552 billion yuan in May, another possible indicator that the government has not yet tamed inflation. But it said total lending in the first half of the year fell by 450 billion yuan to 4.17 trillion yuan.
