Signs of economic strength in China are underpinning further gains in the Australian dollar, now at a three-month high. The Australian dollar is trading at US93.09¢ at 8.20am AEST, up from US92.50c at last night's local close. Local equities also closed higher on Tuesday's trading, with the S&P/ASX200 up 19.7 points, or 0.38%, to 5201.2. China's industrial production rose in August at its fastest rate in 17 months, according to data released by the National Bureau of Statistics. The data comes on the heels of strong Chinese export data on Monday. The S&P/ASX200 is set to open higher this morning as SPI futures are up 29 points.
