BEIJING - An industrial survey has indicated growing confidence among Chinese retailers about business prospects as the country stepped up policy measures to spur growth.

The China Retail Performance Index, a barometer of retailers' expectations for the sector, stood at 50.3 percent in August, edging up 0.2 percentage points from July and staying in the expansion zone for eight consecutive months, according to the China General Chamber of Commerce.

A reading above 50 indicates expansion, while a reading below 50 reflects contraction.
