Now the British are coming. I think Cameron should ask the Chinese government not to make people 'disappear' or to jail them merely because they have different opinions.

Since the global economic crisis began, the change in global attitudes is clear to see - and I think it is pitiful. Barack Obama came to China and he is probably the only president of the United States never to mention the words 'human rights' in public.

We see the tendency in the world to criticise democracy and sometimes even to say that authoritarian countries like China are more efficient. That is very short-sighted. China looks efficient only because it can sacrifice most people's rights. This is not something the west should be happy about.

So maybe there are three parts in my life - earlier background living in exile in Xinjiang in a very political circumstance, then later the United States from 24 to 36 years old. I was quite equipped with liberal thinking. Then the Internet. If there is no Internet, of course, I cannot really exercise my opinion or my ideas.
