China has not established the rule of law and if there is a power above the law there is no social justice. Everybody can be subjected to harm. I'm just a citizen: my life is equal in value to any other. But I'm thankful that when I lost my freedom so many people shared feelings and put such touching effort into helping me.

The 'Bird's Nest' National Stadium, which I helped to conceive, is designed to embody the Olympic spirit of 'fair competition.' It tells people that freedom is possible but needs fairness, courage and strength.

This nation is notorious for its ability to make or fake anything cheaply. 'Made-in-China' goods now fill homes around the world. But our giant country has a small problem. We can't manufacture the happiness of our people.

To work in architecture you are so much involved with society, with politics, with bureaucrats. It's a very complicated process to do large projects. You start to see the society, how it functions, how it works. Then you have a lot of criticism about how it works.

Censorship is saying: 'I'm the one who says the last sentence. Whatever you say, the conclusion is mine.' But the internet is like a tree that is growing. The people will always have the last word - even if someone has a very weak, quiet voice. Such power will collapse because of a whisper.

This week, the world gathers in Beijing for the 2008 Olympic games. This is the extraordinary moment China has been dreaming of for 100 years. People have been longing for this moment, because it symbolises a turning point in China's relationship with the outside world.
