Shawn Wang, who joined the company in 2004, helped Baidu list in the US on the Nasdaq stock exchange the following year. He died on December 27 during a Christmas holiday vacation in China, the company said in a notice seen Sunday on its website. The company did not give further details and officials could not be reached for comment Sunday.

"Shawn's leadership and vision helped transform Baidu into a leading US public company, and his presence will be greatly missed," Robin Li, chairman and chief executive said in the statement.

Baidu.com is the dominant search engine in China, with a 60.7 percent market share, according to research firm Analysys International. US giant Google Inc. is in second place with about 23.7 percent.
