When history is erased, people's moral values are also erased.

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

To become self-aware, people must be allowed to hear a plurality of opinions and then make up their own minds. They must be allowed to say, write and publish whatever they want. Freedom of expression is the most basic, but fundamental, right. Without it, human beings are reduced to automatons.

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.

In February of this year I returned to China to research my next book. The authorities know about the novels of mine that have been published in the west, including the latest one, Beijing Coma, about a student shot in Tiananmen Square, but so far have allowed me to return.

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.

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.
