Chinese not wanted
It seems foreign participation in Australian mining operations is being restricted for security reasons:
"Australia's Defense Department is trying to block Chinese participation in a mining operation within the Woomera missile range. It was feared that the Chinese presence would lead to spying on the many military activities that take place within the Woomera facility."
"This is the second time this year that the Australian government has blocked an attempt by a Chinese government operate in or near Woomera (where some mining is allowed.) Officially, the reason given was that it was too dangerous to operate in the areas the Chinese wanted to work."
Hang on a minute, we pose no threat to China; why would they want to spy on our weapons testing facilities? Then again, we are allied with the United States.
