The Shenzhen Composite Index, which tracks stocks on China's second exchange, dropped 2.79 percent, or 63.77 points, to 2,217.89 on turnover of 536.2 billion yuan.

More than 20 companies in mainland China plan to launch initial public offerings (IPOs) this week, according to the securities regulator, which tends to drain funds from the rest of the market.

The Shanghai market had risen more than 38 percent this year as of Monday's close on hopes of government moves to boost the economy.
