China will release a draft on Chinese depositary receipt rules after the two sessions, news web portal NetEase reported, citing China International Capital Corporation.

The CDR allows investors to deal depositary receipts that carry shares of overseas registered Chinese companies on the A-share market.

The move can help registered Chinese companies go public on China's A-share market, or speed up overseas-listed Chinese companies return to domestic stock markets.

Companies with new technologies, new industries, new commercial activities and new models will be the pioneers of the CDR, the CICC said.

According to Securities Times, the first batch of eight companies includes Alibaba, Tencent, Baidu, JD, Ctrip, Weibo, NetEase and Sunny Optical, who will return back to the A-share market via the CDR.

The market value of the companies totals 7.85 trillion yuan ($1.24 trillion), Citic Securities said. Assuming its issue at 10 percent of market value, the market size of the first pilot CDR will be roughly 785 billion yuan.

Financial media outlet CBN reported, citing an insider, financing via CDR will only be allowed in China's domestic market.
