According to News Australia, Shanxi Evening Post had a news article on actual slavery found in Shanxi. 31 Chinese were forced by the son of a local communist to work as slaves in a brick factory. These slaves were rescued by police.
Whereas the Chinese communists used the excuse of freeing Tibetan slavery to invade Tibet 50 years ago, slavery is still being practiced in China under the communist regime! Can other nations use this an excuse to invade China?
