China’s industrial profits fell 0.6 percent in August from a year earlier, reversing from July’s 13.5 percent annual rise, the government said on Saturday, the latest in a series of weak data from the world’s second-largest economy. China’s National Bureau of Statistics did not give a reason for the August decline. The monthly decline adds to recent weak figures that have fueled fears that China is at risk of a sharp slowdown if it does not make fresh stimulus measures.
