Greg Foran, senior vice president of Walmart International, has been named president and CEO of Walmart's China unit, effective March 1.

Foran, who previously headed the food and liquor business at Sydney-based Woolworths Ltd, Australia's biggest retailer, joined Walmart in October 2011, the same month Ed Chan, his predecessor, resigned. Chan quit amid a pork-labeling probe that shut all 13 of Walmart's stores in the southwestern city of Chongqing.
