Sanyuan Group suffered a loss of 38 million yuan ($6.21 million) in the first half of the year. The Beijing-based dairy group's revenue grew by about 1.8 billion yuan in the first half, a year-on-year increase of 9.35 percent. But its net profit shrunk by 72 million, according to a report released by the group. The loss was caused by market factors, the rise in the cost of raw materials and the decline in investment income, the group said. Only one of Sanyuan Group's five subsidiaries made a profit. The other four - Sanlu Group, Taizi Dairy Group, Shanghai Sanyuan Group and Hulun Buir Sanyuan Group - all reported losses.
