SHANDHAI: China stocks on Wednesday ended higher for the fourth straight session, as investors clung to hopes of a post-pandemic recovery in the world's second-largest economy while the heavyweight services sector continued to expand.

The Shanghai Composite index closed up 0.2% at 3,377.56. The blue-chip CSI300 index edged up 0.03%, the consumer staples sub-index gained 0.6% and consumer discretionary shares added 0.3%. The smaller Shenzhen index rose 0.8% and the start-up board ChiNext Composite index gained almost 1%. The tech-focused STAR 50 climbed 1.4%.

Financial sector stocks, which rallied on cheap valuations on Tuesday, fell 1.2%.

"But people are still buying into China consumption, the big caps are doing okay today. The mood in the market is overall positive," said Alex Wong, director at Ample Finance Group.

The Shanghai stock index is up 10.7% and the CSI300 has risen 16.6% this year. Shanghai stocks have risen 2% this month.

About 38.58 billion shares were traded on the Shanghai exchange, down from the previous session's 44.23 billion.

Growth in China's services sector slowed in July from a decade high the previous month, but remained in expansion territory, an industry survey showed on Wednesday. The sector accounts for about 60% of the economy.

Central bank adviser Ma Jun told local media there is no need to step up counter-cyclical adjustments in monetary policy as an economic recovery is well under way, forecasting 2% growth for 2020.

Senior US and Chinese officials will review the implementation of their Phase 1 trade deal on Aug. 15. Beijing's top US envoy said it does not want further tensions.
