An article on a website associated with the National Administration for the Protection of State Secrets accused Anglo-Australian miner Rio Tinto of overcharging China for its iron ore by more than US$1 billion over the past six years, Bloomberg reported. "That means China gave the employer of those economic spies more than $100 billion for free, which is about 10 percent of Australia’s GDP. It also caused the serious consequence of climbing losses in China’s pillar industry of steelmaking," the article on baomi.org said. Rio Tinto declined to comment, but earlier said reports that detained Rio Tinto employees had bribed steel mill officials were "without foundation." The Australian government is still trying to gather information about the case against Australian citizen and Rio Tinto executive Stern Hu, who remains in Chinese custody.
