U.S. Secretary of State Hillary Clinton and Defense Secretary Leon Panetta met Australian Foreign Minister Kevin Rudd and defense chief Stephen Smith in San Francisco, California, for talks on September 15.

The subject was cyber attacks. Panetta called cyberspace the battlefield of the future, and most of the intensive cyber attacks in the past year are believed to have originated in China.

The new cyber war policy involves putting U.S. troops in Australia, for training purposes.
