Drinks giant Coca Cola is to pay $2.5bn (£1.4bn) for Chinese juice company Huiyan, to boost its presence in one of the world's quickest growing markets.The firm will pay 12.20 Hong Kong dollars per share - about three times the firm's closing price on Friday.French food group Danone owns almost a quarter of Huiyan. While the Chinese pure fruit juice sector is currently limited, there is scope for growth as wages and living standards improve, analysts said. Huiyan has 43% of China's pure juice market, according to AC Nielsen. "Though it's a relatively small market in the beverages space, it's a high-growth market because of the growing personal income in China and increased health awareness," said Emma Liu, an analyst with Nomura Securities.The juice sector in China - including pure juice and diluted drinks - is set to expand by more than 10% in years ahead, as incomes rise, analysts predicted.
