China manufacturing index falls to six-year low in September

Global investors unsettled as survey shows China's factories cut output, staffing and prices at a faster pace as both new export orders and overall new orders fall

Chinese manufacturing activity fell to its lowest in more than six years in the latest sign of the slowdown in the world's second-biggest economy, according to a survey released on Wednesday.

The latest data was worse than economists had expected and unsettled global financial markets. Uncertainty about the extent of China's slowdown has been on the radar of investors, particularly after the Federal Reserve mentioned China as one of its reasons for not raising interest rates last week.
