“In a way that surprises even many experts, the repression campaign by the powerful Communist Party propaganda department here, including decade-long prison terms for Web bloggers - has again raised the image of China as seriously lagging in rights and liberal values that much of the world takes for granted. It has awakened a moral language of justice and condemnation, as seen last week on Capitol Hill when members of Congress berated Internet company officials for complicity with Chinese security police.”
Ok, my questions are:
What does “campaign” mean here?
What does this “it” refer to?
