Obama: More US troops to be stationed in Australia

Australia has agreed to host a full US Marine task force in the coming years, Prime Minister Julia Gillard has announced at a news conference with US President Barack Obama in Canberra.

She said about 250 US Marines would arrive next year, eventually being built up to 2,500 personnel.

The deployment is being seen as a move to counter China's growing influence.

But Mr Obama said the US was "stepping up its commitment to the entire Asia-Pacific", not excluding China.
