Vietnam's Kinh Do Confectionery Co. has acquired the local Wall's ice cream business from Unilever for an undisclosed sum. Wall's ice cream factory, which can produce 9 million liters of ice cream a year, will be the base for Kinh Do's push into the domestic ice cream market. Unilever invested $20 million in setting up the Wall's operation in Ho Chi Minh City in 1997.
