Google China has announced that Dr. Kai-Fu Lee, global vice president of Google and president for Google China, has resigned and will depart from the search engine company in the middle of September 2009.

On Lee's departure, Boon-Lock Yeo, director of Google's Shanghai engineering office, will take over the engineering and development responsibilities for Google China; and John Liu, who is currently in charge of Google Greater China's sales team, will assume Lee's business and operating responsibilities.

Lee previously worked for Microsoft, and he joined Google in 2005. Under Lee's four-year leadership, Google China gained some achievements in search quality, product development, and partner relations in China. Lee promoted the launch of Google China's domain name, Google.cn, and helped Google China launch a series of products, covering map, mobile search, and translation services.

Lee will start his own business in Beijing after leaving Google.
