I think the rules of conduct that we had, say, at the height of the Cold War between the Soviet Union and the allied forces were pretty well demarcated in how to work together to avoid having an event that would snowball. I think we don't have that in place with the PRC today, and that's one of the challenges we see in the South China Sea, off the coasts of Japan, South Korea and Taiwan.
We are seeing them undertake quite dangerous activities and there is the potential for an act that will result in casualties. In fact, there was an event with fishers off the island of Kinmen recently.
This is one of the concerns, and it is one of the reasons that you need to continue to engage with China. Notwithstanding the fact that we're picking friends and choosing sides, you still need to keep the lines of communication open with your adversaries to avoid things that would complicate things as a result of miscalculation or behaviours which create an accident and kill people.
