The Bank of England said it was pretty skeptical about China hitting its 7 percent growth target this year. Whether Chinese policies aimed at stimulating internal demand will actually work is "a key uncertainty," the Bank said. The Bank also said that an "underlying slowdown" in investment and lending might last longer than people think, Reuters reported. China surprised the markets this month, producing official data to show real GDP growth at 7.0 percent in the second quarter, above analysts' estimates of 6.9 percent. But not everyone believes the numbers. Citigroup said in a note this week that China is inflating its figures and "in practice, 'genuine' GDP growth probably is below 5 percent." Chinese stocks have fallen by more than 30 percent since the middle of June, and may keep going if skeptical voices like these keep piling up.
