Ai Weiwei

Ai Weiwei

Collection of Ethan Warsh

Ai Weiwei is the kind of visionary any nation should be proud to count among its creative class. He has drawn the world's attention to the vibrancy of contemporary Chinese culture. More important, Ai, 53, has shown compassion for his fellow citizens and spoken out for victims of government abuses, calling for political reforms to better serve the people. It is very sad that the Chinese government has seen a need to silence one of its most innovative and illustrious citizens. For the world, Ai continues to represent the promise of China.
