I think that the exchange is very important. Before I did the exhibition in Shanghai, I was a judge for the John Moores Painting Prize and that was very interesting for me, because some of the judges are Chinese and some are British, and we look at the work together. It was fascinating that most of the time we were in complete agreement, but some of the time we were not. People send their works from all over China. For a foreigner, this gave me a very good picture about what is happening in China and its art today.

When I look at the objects that I draw, it seems to me so obvious about the contemporary world - these are our world.

'Understanding' art is like having a sense of humour - if you don't have one, no amount of explanation is going to make you laugh.

There was something really wonderful about being able to feel confident about doing my first exhibition in China, that people would have no trouble recognising the images and understanding my work. I also have a lot of freedom in the way I use colour, and I think that kind of freedom in colour is also understandable in every culture.

In Britain the power of authority was weakened. There was much more individual freedom and there was great academic freedom.

You can't honour someone by copying them or trying to be exactly like them.

In the studio, it took me a long time to work out how to make paintings that had the intensity that I was able to create by painting whole rooms. There is a very limited number of colours but there are many variations. I decided to use the purest palette that I could.
