Wal-Mart (WMT.NYSE) will look to improve operations in the Chinese market by opening more Sam’s Club outlets, the retailer’s warehouse store brand, The Wall Street Journal reported. Wal-Mart’s China chief executive Greg Foran said the company will add two Sam’s Club outlets in China in 2014 to the 10 that have already opened. The rate of new outlet launches could increase each year until it reaches 10 new stores per year in six to seven years. Online, rivals such as Alibaba Group’s Taobao.com dominate. But Mr. Foran said he is aiming to increase efficiency in order to slash the prices of products sold on its Yihaodian online platform, in which it bought a 51% stake in 2012.
