Tencent, the maker of popular messaging app WeChat, is taking its ecommerce ambitions one big step forward today by allowing anyone to set up a store inside WeChat. WeChat first added support for mobile payments in August last year, with only a few brick-and-mortar retailers supporting it. Then the app explored ecommerce shortly after by testing out flash sales of Xiaomi smartphones. By March of this year, both offline and online purchases within WeChat went mainstream, but the eshopping was mainly limited to major brands and retailers.
