Funds raised through initial public offerings (IPOs) on China's Shanghai and Shenzhen stock exchanges is expected to reach 200 billion to 250 billion yuan ($31.4 billion-$39.3 billion) this year, said accounting firm PricewaterhouseCoopers (PwC) on July 3.

During the first half of this year, China's IPO market experienced a slump as uncertain global economic prospects and the euro-zone debt crisis dented investor confidence.

A total of 77.5 billion yuan ($12.2 billion) was raised through 105 IPOs during the January-June period, down 56 percent and 38 percent, respectively, from a year earlier, the report stated.

The ratio was still higher than the average international level, said Sun Jin, a partner at PwC China.

But a report by accounting firm Ernst & Young said only one Chinese company—online discount retailer Vipshop—held a successful initial public offering (IPO) in the United States during the first half of this year, down from 13 in the same period last year.

Nineteen Chinese companies were delisted from stock exchanges in the United States during the first half, according to the report.

Ivan Tong, assurance partner with Ernst &Young, said more Chinese companies are seeking delisting partly because the stock prices are lower than expected, therefore "they would rather wait for better chances and better markets."
