Growth in China’s services sector weakened slightly in September as new business cooled, a private survey showed on Wednesday, reinforcing signs of a slowdown in the world’s second-largest economy that could prompt more stimulus measures. “Overall, the services sector held up in September, despite the downward pressure seen in the manufacturing sector. We think risks to growth in the near term are still on the downside, and warrant accommodative monetary as well as fiscal policies,” said Qu Hongbin, chief China economist at HSBC.
