Wal-Mart Stores reopened all of its 13 stores in the western city of Chongqing two weeks after local officials ordered it closed for mislabeling pork, the Wall Street Journal reported. The multinational retailer was fined and ordered to halt its operations after 37 employees were detained following an investigation on October 6. Wal-Mart said it has overhauled its operations, trained employees to comply with local laws and regulations, as well as created food inspection labs at its stores in an effort to improve food management. The retailer has also put a customer complaint counter in its Chongqing outlets. “In the case of supermarkets, consumers are more likely to forgive. Many shop at Wal-Mart for convenience,” said Aaron Fischer, an analyst at CLSA. The US retailer has been expanding rapidly across China, and currently operates 353 stores in the country.
