Chinese Vice Premier Wang Yang said Tuesday more should be done to improve the dairy sector.

The sustainable and healthy growth of the dairy sector is important for health, agricultural restructuring and higher incomes for farmers, Wang said at a summit which attracted 20 key dairy producers.

The dairy firms should improve quality and rebuild consumer confidence in domestic dairy products, he said.

Chinese consumers have turned to overseas milk products since melamine was found in baby formula produced by China's Sanlu Group in 2008.
