I believe that the power of literature is stronger than the power of tyranny.

The Chinese people have been forced to forget the Tiananmen massacre. There has been no public debate about the event, no official apology. The media aren't allowed to mention it. Still today people are being persecuted and imprisoned for disseminating information about it.

I wanted to analyse and understand how the Chinese people could have their lives so crushed by fear.

I meant that the Chinese people are not aware of their own entrapment. They believe they live in a free society, but don't realize how much they are being monitored and controlled, how much the information they receive is restricted and warped, until they step out of line, that is, and feel the heavy hand of the state fall on them.

My hope is that the Chinese government will come to realise that it is futile to repress free speech, and that contrary to what they believe a regime's strength rests not its suppression of a plurality of opinions and ideas, but in its capacity and willingness to encourage them.

Beijing Coma took me 10 years to finish.

In 1989, I was on Tiananmen Square with the students, living in their makeshift tents and joining their jubilant singing of the Internationale. In the two decades since, each time that I have gone back, visions from those days seem to return with increasing persistence.
