COFCO acquired 20% of Mengniu Group in 2009 for HK$6.1 billion, making it the largest shareholder of Mengniu Group. However, this is not the same as Mengniu being fully acquired by COFCO. Mengniu Group made a series of acquisitions in the following years, including the purchase of dairy companies such as Guangdong Yashili, Dometic China, and Modern Farming, in order to expand its product line and market share. As a result, Mengniu Group was not fully acquired by COFCO.
