Company plans to open several Sam's Clubs, 28 more supercenters in China

The world's largest retailer by sales, Wal-Mart Stores Inc, will open approximately 30 retail stores and additional distribution centers in China this year after shuttering several underperforming stores.

The new stores will comprise 28 supercenters and two Sam's Clubs. Supercenters will continue to open in first- and second-tier cities, such as Shanghai, Changchun of Jilin province and Wuhan of Hubei province, but also in lower-tier cities, including Fuyang of Zhejiang province and Xingtai of Hebei.
