Japanese fashion empire Fast Retailing Co. says it will expand monitoring of its suppliers following complaints over labor violations and other problems. Yukihiro Nitta, who is in charge of corporate social responsibility at the fashion giant, said Wednesday the company's oversight would extend to the fabric manufacturers who supply the garment companies that make clothes for Fast Retailing. ... The company plans to have a pilot program involving 30 percent of the fabrics used in Uniqlo clothing in place by the end of March, and to expand it to all of its textile suppliers by March 2016. ... "We believe that respect for human rights and ensuring fair working conditions are top priorities for the entire industry, and not just Fast Retailing," said Nitta, the corporate social responsibility executive.
