Ai Weiwei has launched a social media campaign in defence of freedom of press following the news of a recent high court ruling that overturned an earlier decision and judged in favor of allowing julian assange to be extradited to the US.

“The installment also includes marble and jade sculptures such as Marble Helmet (2015) and Marble Takeout Box (2015) along with the ceramic work He Xie (2011) which commemorates the feast hosted by Ai Weiwei amid the demolition of his Shanghai studio by the Chinese authorities in 2010.”

Artist and activist Ai Weiwei wants the world to pay close attention to a recent British court ruling regarding WikiLeaks founder Julian Assange—so he’s taken to his treadmill.
