Warehouse club operator Costco Wholesale Corp said it will make its China market debut through the opening of an online flagship store on Alibaba Group Holding's Tmall Global, a wing of business-to-customer tmall.com.

Costco's online store launch targets consumers in the Chinese mainland and the online store will initially provide a range of products including food and healthcare product listings at competitive prices, the company said in a statement on Tuesday.

Costco said tmall.com's warehouse store helps to cut logistics costs and delivery time.

On the same day, Alibaba unveiled its plan to help mobile developers to lower cost in devising their respective app, via its cloud computing technology and other assets.
