Costco to Enter China Through Alibaba's Tmall

U.S. warehouse club operator Costco Wholesale said it would open an online store in China using Alibaba Group's fast-growing Tmall online marketplace, entering the country's booming e-commerce market to combat slowing sales at home. Costco said the online store would provide customers in mainland China with both branded products, which would initially include food and healthcare goods, and also products under its Kirkland Signature private-label business.
