It is not a surprise that the social app by Facebook, whatsapp is blocked by Chinese government. I want to mention here that many social sites such as Facebook, Twitter and YouTube are already blocked in china and now another social app is blocked by China recent days.
To make it more secure, Chinese government has removed vpn software and apps from the play stores so that no one can use such kind of apps. This makes difficulty for foreigners to keep in touch with their relatives in the home country.
