The purchasing managers' index (PMI) for China's manufacturing sector stood at 49 in October, down 0.8 percentage points from September, official data showed on Friday.

The PMI for the non-manufacturing sector, which includes services and construction, came in at 50.1 in October, up 0.1 percentage points, a survey by the National Bureau of Statistics showed.

The mixed data is expected to spur calls for further stimulus measures to boost domestic demand.

"Economic momentum has weakened since the middle of the year. The property-sector slowdown continues to put pressure on domestic demand," said Zhiwei Zhang, chief economist at Pinpoint Asset Management.

Beijing pledged to boost domestic consumption following a four-day closed-door meeting last week that outlined economic and policy objectives for the next five years, while also emphasising efforts to strengthen its vast industrial system.

Some analysts believe Beijing doesn't need more stimulus this year while others see speeding up infrastructure investment as a way to ensure the economy remains on target in the fourth quarter. (Reuters/Xinhua)
