When is information in the public domain not public any more? When it relates to Chinese economic or social development.
Rio Tinto have been accused by the Chinese government of engaging in industrial espionage, probably the greatest example ever of black pots and kettles, and 4 RT employees have been arrested.
However, it appears that the issue may be complicated by China’s laws on the protection of state secrets, which as one would expect from a totalitarian state, give maximum flexibility to state officials and very little to private or corporate citizens.
It seems that the law has empowered Chinese state officials to classify public information as “secret” if it is related to economic and social development or “other issues”.
