Ai Weiwei: Refugees should be respected

Renowned Chinese artist and activist Ai Weiwei has said that refugees are not "beggars" or people to be "pitied" but should be respected because they are "just like us".

In this new documentary Human Flow, he describes what he witnessed while visiting the Greek island of Lesbos and how he dealt with such a sensitive subject.
