China’s manufacturing sector returned to expansion in September after two consecutive months of contraction, with easing weather disruptions allowing factories to resume normal operations while strong global demand linked to artificial intelligence provided additional support to industrial activity.

BEIJING — China’s factory activity returned to growth in September, offering a positive signal for the world’s second largest economy as manufacturers benefited from improved operating conditions and continued momentum from the global artificial intelligence boom.
The official manufacturing purchasing managers’ index, or PMI, increased to 50.1 in September from 49.8 in August, according to figures released Wednesday by China’s National Bureau of Statistics.
The result ended two consecutive months of contraction in the manufacturing sector.
It also matched the median forecast of 50.1 in a Reuters poll of economists.
Manufacturing crosses back into expansion
The PMI is one of the most closely watched indicators of industrial conditions in China.
A reading above 50 indicates an expansion in manufacturing activity, while a figure below 50 signals contraction.
September’s reading of 50.1 therefore places the sector narrowly back into growth territory.
Although the improvement was modest, crossing the 50 point threshold is significant after factory activity contracted during the previous two months.
The index had stood at 49.8 in August.
Weather disruptions ease
Improving weather conditions contributed to the September recovery.
Earlier disruptions had affected industrial activity and prevented some factories from operating normally.
As those conditions eased, factories were able to resume operations, supporting the improvement recorded in the official survey.
The rebound indicates that at least part of the weakness seen during the preceding months was associated with temporary operational disruptions rather than a uniform deterioration across manufacturing.
AI boom provides industrial support
China’s manufacturing sector is also receiving support from the continuing global expansion of artificial intelligence.
Rapid investment in AI infrastructure has created demand across interconnected industries involved in producing technology equipment and components.
The artificial intelligence boom has become an increasingly important force across the global technology industry as companies and governments invest heavily in the computing infrastructure required to develop and operate increasingly sophisticated AI systems.
For China, with its enormous industrial base, that expansion provides opportunities for manufacturers connected with technology supply chains.
A narrow but important return to growth
The September result does not indicate a dramatic manufacturing acceleration.
At 50.1, the official PMI sits only marginally above the dividing line between expansion and contraction.
The figure nevertheless represents an improvement after two months in which manufacturing activity remained below that threshold.
It also met economists’ expectations, suggesting that the recovery was broadly consistent with forecasts for the sector.
The coming months will show whether September marks the beginning of a sustained industrial recovery or primarily reflects factories returning to normal activity following weather related disruptions.
For now, the official survey provides Beijing with an encouraging signal: after two consecutive months of contraction, China’s vast manufacturing sector has returned to growth.
