Wal-Mart Stores, the world's top retailer, has fired about 30 senior executives in China, including several in Hong Kong, amid a restructuring in Asia that includes store closures in Japan and management changes in India. The departure of the executives, including directors and senior staff, was to streamline and simplify the business and was "consistent with actions taken over the last several months", said Ray Bracy, a spokesman for Wal-Mart in China. A small number of the employees mutually agreed to leave, Bracy said. The move comes amid a management shake-up in the US, where Wal-Mart announced the departure of the company's US merchandising chief on Tuesday. Wal-Mart also reappointed Scott Price as Asia chief this month as the retailer faces headwinds in its biggest markets in the region. US-based Wal-Mart is encountering stiff competition in China and also dealing with food safety scandals such as fox DNA found in donkey meat. The retailer said in October last year it planned to add as many as 110 stores over three years in China, while shutting some outlets and remodelling dozens more as it overhauled its business. Among the executives dismissed are vice-presidents from Wal-Mart China and Sam's Club China, according to two Wal-Mart China employees. Bracy declined to comment. Some staff in the human resources department in Hong Kong were also dismissed, while employees in the real estate division were moved to Wal-Mart China's headquarters in Shenzhen, said two company officials familiar with the matter, who asked not to be named. Hong Kong-based vice-presidents in charge of the two divisions have left the company, according to the people. Wal-Mart did not respond to queries about dismissals in the city, which traditionally served as the retailer's headquarters for Asia, overseeing businesses in mainland China, Japan and India. Price is taking charge of a region where the retailer is also closing about 30 outlets in Japan as it focuses on fresh food offerings, according to the company.
