Danone established a joint venture company with the Wahaha Group in 1996, with a 51 percent ownership stake of stock in the company. In addition to this joint venture company, the Wahaha Group also operated several separate non-Wahaha joint ventures. In 2007, Danone attempted to offer four billion Yuan to purchase 51 percent of the shares of all non-Wahaha joint ventures, but this offer was rejected. Subsequently, Danone was involved in a series of complex litigation against the Wahaha group in a number of jurisdictions.
