Alibaba Group Holding will spend more than CNY2 billion buying 32% of Sanjiang Shopping Club Co, a regional Chinese discount supermarket chain with more than 1 million members. Shares of Sanjiang surged by its daily 10% limit on the news, giving the Ningbo-based company a market value of about USD830 million. Alibaba’s Jack Ma’s goal is to replace distributors and middlemen and let stores buy directly from suppliers based on real-time demand and inventory.
