An hour ago I spoke with Sydney Morning Herald International Editor Peter Hartcher on where South China Sea tensions are heading.

I was intrigued by a phrase Peter used in his Monday column, where he referred to Beijing's land reclamation in the South China Sea as a 'creeping invasion of the region'.  As you will hear, Peter says Chinese strategists have themselves used similar phrasing. Peter also talks about what the US wants to do next to demonstrate its resolve in this dispute, and we end by discussing Australia's role. If there's a skirmish or an accident between US and Chinese forces, what will Australia do?
