China's leading internet search engine Baidu.com is in talks with regulators over a domestic listing, Reuters reported. The company's Chief Financial Officer Shawn Wang said at the weekend that informal talks have been held with the China Securities and Regulatory Commission (CSRC) but a number of legal barriers stand between Baidu and a home share offering. The search giant is officially a wholly foreign capital-invested company and such firms are not allowed to list on China's stock markets. However, it was reported earlier in the year that the CSRC is considering allowing foreign firms to issue Chinese Depositary Receipts. Wang said a domestic listing would further Baidu's plans to acquire search engine-related companies in China. The company debuted strongly on NASDAQ last year, with shares quadrupling in value on the first day of trading, the biggest one-day gain by a foreign company in the US.
