The Caixin/Markit Services Purchasing Managers' Index (PMI) for China climbed to 52.0 in October from 50.5 in September, exceeding expectations for an increase to 50.8.

The index was driven by a further increase in total new business.

"The Caixin China Services PMI is 52.0 for October, up significantly from 50.5 the previous month. The Caixin Composite Output Index reached 49.9, also much higher than 48.0 in September, close to the neutral 50-point level. This shows that previous stimulus policies have begun to take effect, while the economic structure steadily improved," Dr. He Fan, Chief Economist at Caixin Insight Group, said.

"The economy has started to show signs of stabilizing, reducing the need for a further stimulus. The government must be resolute and push forward the reform agenda in a well-rounded manner to release the long-term potential for sustainable economic growth," he added.
