The Shanghai Composite fell 0.37% to 3,560 while the Shenzhen Component lost 0.17% to 10,991 on Friday, snapping a five-week winning streak as weaker-than-expected manufacturing data weighed on sentiment. A private survey showed factory activity slipped back into contraction in July, missing expectations for a second consecutive month of growth amid ongoing global trade uncertainty. While US and Chinese officials concluded trade talks in Stockholm earlier this week, President Donald Trump has yet to approve an extension of the current tariff truce. Adding to investor concerns, the Politburo meeting offered no significant stimulus, disappointing markets hoping for stronger policy support to combat deflationary pressure and sluggish growth. Technology stocks led the retreat, with Eoptolink Technology and Zhongji Innolight both down 3.2%, and Foxconn tumbling 4.7%.
