China's chief quality supervisor Li Changjiang stepped down on Monday afternoon with the approval of the State Council after tainted dairy products sickened nearly 13,000 infants and killed three.

Wang Yong replaced him as the director of the General Administration of Quality Supervision, Inspection and Quarantine and was removed from his former post of the deputy secretary-general of the State Council.
