US retail giant Wal-Mart has said it remains confident it can turn around its struggling affiliate Seiyu, despite the Japanese chain posting first-half losses on Tuesday. Seiyu, Japan's fourth-largest retailer, reported a group net loss of ¥8.43bn (US$76.7m) for the six-month period, compared to a year-earlier net loss of ¥22.39bn. The year-ago result included almost ¥35bn in special charges related to a group reorganisation and stock losses.
