The Shanghai Composite slipped 0.15% to below 3,470, while the Shenzhen Component fell 0.6% to 10,450 on Monday, as mainland stocks gave back some of last week’s gains amid lingering trade uncertainty. Investor sentiment was dented after US President Donald Trump confirmed that sweeping reciprocal tariffs will take effect on August 1. Treasury Secretary Scott Bessent earlier warned that tariffs would revert to April 2 levels for countries that have not secured a deal with the US by that date. So far, only China, the UK, and Vietnam have reached partial trade agreements with Washington. Investors are also awaiting fresh inflation and trade data from China this week, which may offer clues on how the evolving US-China trade dynamic is impacting the world’s second-largest economy. Among the notable decliners were Zhongji Innolight (-4.1%), Victory Giant (-1.5%), and Eoptolink Technology (-1.7%).
