His comments came after Pyongyang said it was making plans to fire missiles over Japan to land near the US Pacific territory of Guam. Financial markets have largely taken the geo-political tensions in their stride, that is until today.

Aaron Connelly, research fellow at the Lowy Institute joins PM to discuss how the US has sailed into another highly sensitive part of the globe. A Reuters story is quoting unnamed US officials as saying a US Destroyer conducted a freedom of navigation operation in the South China Sea yesterday, sailing within 12 nautical miles of the Spratly Islands. The manoeuvre has antagonised China which has says it owns the island group and for several years has been building military installations to bolster its hotly contested claim.
