Thank you for that very interesting question.
As far as I know, there are over 200 democratic organizations outside of China, and they are helping to push the human rights improvement inside the country. I think western countries need to understand China more, or more deeply, because we need help and support from friends here and from other countries to promote China's human rights improvement.
For example, a dissident reporter from Hong Kong, whose name is Ching Cheong, was sentenced by the government to five years in prison due to pressure from other countries, from western countries, whereas another person, whose name is Lu Jianhua, was sentenced to 20 years, but was sentenced quietly, so nobody knew that. There was no pressure, and the sentence was much longer.
