The benchmark Shanghai Composite Index lost 1.3 percent, or 37 points, to 2,886, while the Shenzhen Composite Index, which tracks stocks on the mainland's second exchange, closed 1.8 percent, or 27 points, down at 1,532.
Twenty-five stocks debuted on the Shanghai Stock Exchange's Sci-Tech Innovation Board – dubbed the STAR Market – in which listing and trading rules have been eased to help channel funding to start-ups.
Anji Microelectronics Technology (Shanghai) Co. was one of the stand-out performers, soaring more than 500 percent at one point before paring gains to end up 400 percent.
There will be no limits on price movements for the first five days of trading, after which a daily 20 percent band is imposed. China's main exchanges are subject to a 10 percent band to contain volatility.
Tokyo ended 0.2 percent lower. Sydney, Seoul, Singapore, Manila and Jakarta were also lower, though Wellington and Taipei edged up. (AFP)
