The China Securities Regulatory Commission has issued draft rules to encourage overseas-traded Chinese companies to list domestically and to make it easier for big state companies to go public, Bloomberg reported. In a draft document sent to brokerages, the regulator proposed scrapping limits on the amount that can be raised in IPOs, currently set at twice net assets, and on transactions with affiliates, which are capped at 30% of annual sales. It also suggested separate rules to permit the sale of China Depositary Receipts by Hong Kong-incorporated companies that have their headquarters and operations on the mainland. The moves are aimed at reviving stock benchmarks that fell to eight-year lows last year. The Shanghai and Shenzhen stock exchanges were the world's fourth-worst and third-worst performers in 2005, respectively.
