Chinese artist Ai Weiwei on the real cost of activism | China Tonight

Ai Weiwei was once described as the ‘most influential artist of our time'.

His representation of modern China was a centrepiece of the 2008 Beijing Olympics – but in the years since, his growing criticism of the Chinese government has put him at odds with authorities.

In 2015, he left the country – but his activism continues.

He talks to Stan Grant about freedom, his art – and the Chinese Communist Party.
