Why Ai Weiwei was jailed

The Chinese artist Ai Weiwei has been ordered to pay 15m yuan (£1.5m) in tax by officials after being detained for almost three months this spring. After being released, Ai Weiwei told the Guardian that he did not owe any tax money, adding "It's a game they play all the time … They needed an excuse to take me away for 81 days."
Ai said that the tax money was actually owed by Fake, a company that handled all of his affairs but is legally registered by his wife:

"I am a designer for the company; I am not the legal representative, nor the manager… I never signed papers or made a deal or transferred money – I was nothing to do with the accounting. They said I was the 'actual controlling person' of the company."
