THE United States President, Barack Obama, has taken aim at China over everything from human rights to regional security in a provocative speech to the Australian Parliament to underscore America's intention to increase its presence in the Asia-Pacific region.
Addressing a joint sitting of Parliament this morning, Mr Obama said as the tide of war was receding in the Middle-East and Afghanistan, America was "looking ahead to the future we must build".
"Let there be no doubt, in the Asia-Pacific in the 21st century, the United States of America is all in," he said.
Mr Obama said the US was a Pacific nation and its military, along with Australians, had fought and died in the region and its mission now was to promote security, prosperity and human dignity.
"Americans have bled with you for this progress and we will never allow it to be reversed," he said.
