Who were and are exposed to human rights violations, genocide, involuntarily imprisonment, deforestation of their land, mining exploits, etc
The group who organized the event has more information at this website.
There is concern that China who is hosting the 08 Olympic is not following its agreement to improve the human rights in its country. The march highlights China un-willingness to cooperate and to be just. There is no justice as long as China is suppressing the truth and the flow of information in their country, and by neglecting international concerns of human rights abuses.
