China’s economy showed more signs of strain Monday as the country published weak data for industrial output, investment and retail sales, amid a lingering trade war with the United States. Industrial output grew by 4.4 percent year-on-year throughout August, falling to its lowest level in 17 years and down from 4.8 percent in July. The figure was well below analyst expectations, with a Bloomberg survey of analysts predicting heartier growth of 5.2 percent.
