Uniqlo parent Fast Retailing Group has issued a statement defending itself after being named in a report on working conditions in a Cambodian clothing factory.

Human Rights Now, an international NGO, has highlighted what it considers worker rights abuses at a number of clothing factories in Cambodia, including Zhong Yin (Cambodia) B Textile Co., Ltd.

Uniqlo has confirmed it has a contractual relationship with Zhong Yin.

“Although also mentioned in the report, Fast Retailing Group brand GU does not have a contractual relationship with Full Fortune Knitting Ltd. or ECO Base Factory Ltd, but does with a factory belonging to the same group, and Fast Retailing is currently checking the details,” the Japanese apparel giant said in its statement.

“At the same time, Fast Retailing has begun an inspection of working conditions at Zhong Yin (Cambodia) B Textile Co, Ltd, and if any problem is found, will urge the factory to initiate improvements and help the factory to implement them as soon as possible.”

Fast Retailing said it was a “top priority” to respecting human rights and ensure fair working conditions. The company established a Code of Conduct for Production Partners in 2004, and says it has since regularly monitored working conditions at all of its production partners, including new partners.

“From January 2015, Fast Retailing enhanced its workplace monitoring further, and from February conducted a workplace monitoring pilot program at the suppliers that provide textiles to its production partners. It will complete monitoring all of these textile suppliers by the end of March 2016.

“From April 2015, Fast Retailing will also introduce impromptu, unannounced monitoring at all garment factories currently engaged with UNIQLO, as well as major garment factories working with GU.”
