On Thursday, China's stock markets closed lower, with the Shanghai Composite declining 0.32% to 4,093 and the Shenzhen Composite falling 0.88% to 15,043. This retreat followed a recent rally that saw both indices reach one-month and four-year highs, respectively. Investor sentiment was negatively impacted by ongoing geopolitical tensions, particularly related to conflicts in the Middle East, where Iranian forces have reportedly targeted commercial vessels. Additionally, the United States has been enforcing restrictions on ships associated with Iranian ports. Market attention is now shifting towards the upcoming session of the National People's Congress Standing Committee, scheduled for April 27-30, where lawmakers are expected to review significant legislative measures, including revisions to the Prison Law. Among individual stocks, significant declines were noted for Zijin Mining Group (-3.18%), BYD (-1.61%), Eoptolink Technology (-2.32%), Suzhou TFC Optical Communication (-6.74%), and Muyuan Foods (-2.75%).
