The purchasing managers' index (PMI) for the manufacturing sector rose to 51.0 per cent in August from 50.3 per cent in July, marking the second monthly expansion in a row, and the highest reading this year, according to China Federation of Logistics and Purchasing (CFLP).
The index tracks manufacturing activity in China's factories. A number below 50 indicates contraction, while figures above it points towards expansion.
The 70 basis points expansion also represents the biggest increase since January.
Zhao Qinghe, a senior statistician with the National Bureau of Statistics (NBS) said, new data shows the manufacturing activities have stronger growth impetus, and the economy is firming in a more evident way.
