Investor sentiment was dampened by the absence of fresh market catalysts and ongoing geopolitical uncertainty. Tensions in the Middle East remained a key concern after Iranian forces reportedly fired on commercial vessels, while the United States continued enforcing restrictions on ships linked to Iranian ports.

Market focus has also shifted to the upcoming session of the National People's Congress Standing Committee scheduled for April 27'30, where lawmakers are expected to review draft revisions to the Prison Law and discuss other legislative measures.

Among individual stocks, notable declines were seen in Zijin Mining Group (-3.18%), BYD (-1.61%), Eoptolink Technology (-2.32%), Suzhou TFC Optical Communication (-6.74%), and Muyuan Foods (-2.75%).
