--FILE--Tins of Dumex baby formula of Danone are for sale at a supermarket in Rizhao city, east Chinas Shandong province, 30 March 2014. Danone agreed to pay HK$4.39 billion ($566 million) for a 25 percent stake in Yashili International Holdings Ltd. under a plan to improve technology and boost production at the Chinese infant milk formula maker. The Paris-based maker of Dumex baby milk powder offered HK$3.70 per share, 17 percent more than the last closing price, according to a Hong Kong stock exchange statement. The investment broadens Danone¯s role in China¯s baby formula market, which is projected to more than double to 191 billion yuan ($31 billion) in the four years ending 2017, according to Euromonitor International. That growth outlook has led to intensifying competition, with analysts predicting a 13 percent drop in annual sales this year at Yashili, a unit of China Mengniu Dairy Co., according to data compiled by Bloomberg.
