In my opinion, Ai Weiwei is one of the major artists of the early 21st century. My gallery avoided the gold rush for Chinese art in the boom years because, in my experience, it's almost always a false premise to group artists together by generation or nationality. What's important is the quality of the individual artist, and it was clear to us that Ai Weiwei stood apart. He's not just the most important Chinese artist of his generation but a truly international figure.
His work is a very interesting blend of traditionalism and liberalism, with a revolutionary bent. He has an outspoken nature, which is what has got him into trouble, but my reading is that his primary impulse is less to overturn society than to improve it. He is unwilling to keep quiet in the face of ignorance and prejudice and he speaks out against injustice wherever he finds it.
They have accused him of tax evasion, bigamy and spreading pornography on the internet, but these charges are clearly trumped up. If you want to nail somebody and put them away for a while, you can probably find dirt on anybody on the planet, let alone a controversial artist like Ai Weiwei. Some people have commented that the Chinese government saw what was going on in north Africa and the Middle East and got nervous. That may well explain his arrest.
