Melamine, often used in the manufacturing of plastics, was added to sub-standard or diluted milk to make the protein levels appear higher.

China on Wednesday set temporary limits on melamine content in dairy products. The limits were a maximum of 1 mg of melamine per kg of infant formula and a maximum 2.5 mg per kg for liquid milk, milk powder and cooking products containing at least 15 percent milk.

The State Council, or Cabinet, issued a series of quality control regulations for dairy products on Thursday.

The regulations tighten control of how milk-yielding animals are bred, how raw milk is purchased and the production and sales of dairy food.

They promised more severe punishment for people who violated safety standards and quality control departments that failed to fulfil their duties.
