This film is worth a watch to show how WeChat-which started as a messaging app- is evolving into a one stop killer app for search,social and shopping. (And you thought Google and Facebook were too powerful.). It’s success is due not to Chinese govt support but innovation to make the user experience a) very easy b)integrated c) time saving.
You can be sure that Facebook and other are eyeing WeChat with envy and trying to emulate it
I expect the anti-trust authorities in Europe and USA to have a say on this trend
