HONG KONG, Dec 7 (Reuter) - said it would apply to the China Securities Regulatory Commission for permission to offer 20 million class A shares in the Shanghai stock market.

Shengdi would be the first firm in the Tibetan Autonomous Region to be listed if the application is approved, a company official told the China Securities Bulletin.

A shares are reserved for Chinese domestic investors.

The official said the Lhasa-based company would use the share proceeds to develop tourist facilities in Tibet and expand its output of mineral water.

The company evolved from a merger between Tibet Natural Mineral Water Co and Tibet International Sports Tourism Co, the official said.

Beijing-based Trust and Investment Co, under the People's Insurance Co, would be the lead underwriter for the issue.

Despite its name, Shanghai-listed Tibet Pearl Star Co is based in Chengdu, the capital of southwestern Sichuan province.
