There were some spat over Rio Tinto earlier. While foreign investments are required by any country including Australia, yet Australia has been chary over the growing influence of China in seas and territory south of China. As a part of ANZUS, Australia has to be sensitive to US concerns. Therefore, it is not unusual that while publicly not indicating discrimination, yet Australia internally are wary over the Chinese acquisitions within Australia. The Chinese have been buying/ investing in raw materials the world over in a hell fired hurry so that it can use it to close the gap with the US in manufacturing and in military hardware.
