China stocks reversed earlier gains to fall on Friday, posting their biggest weekly decline since early May, as weak factory data and lingering trade worries weighed.

The blue-chip CSI300 index fell 1.0%, to 3,633.53, while the Shanghai Composite Index slid 0.7% to 2,774.75.

For the week, CSI300 was down 3%, while SSEC shed 3.2%, both logging their steepest weekly declines in three months.

China's factory gate prices shrank for the first time in three years in July, stoking deflation worries and putting pressure on Beijing to deliver more stimulus as the economy sputters amid an intensifying trade war with the United States.
