FRANKFURT: The German clothing group Hugo Boss is betting on China to improve its prospects as it leaves a difficult year behind, its chief said in an interview to appear on Thursday. Boss currently has 90 stores in China and plans to open 20 to 30 new stores each year there, Claus-Dietrich Lahrs told the business magazine Capital. In October, Lahrs said Hugo Boss would have to make 40 per cent of its sales outside Europe in future.
