The Shanghai Composite index fell 51 points, or 1.7% to 2,979 on Tuesday, after latest economic data showed new home prices, industrial output and retail sales grew at a slower pace in August. Also, the Hong Kong’s Hang Seng index lost 392 points, or 1.5% to 26,724, after the credit ratings agency Moody’s lowered Hong Kong outlook to negative amid the ongoing political protests. Concerns about global oil supply and its consequences after an attack on Saudi Arabia’s major oil facility on Saturday also hit sentiment.
