Thank you for the question.
To add to what my colleague said, I think there are three main points.
I would agree on deterrence. We absolutely need to build up deterrent capability. Many of the allies in Asia do as well. For example, Japan still hovers at around 1% of GDP spending, which is almost half of what NATO requires from most of its allies, even though some of them don't meet 2%. I think Japan is one example of an ally that needs to be doing more in terms of defence spending. Deterrence is a big one.
The second one, obviously, is diplomacy. I think we need to work publicly and privately to signal to the Chinese that there are certain thresholds and certain red lines that can't be crossed.
The third one is contingencies. We have to talk very privately with the Americans, with our Five Eyes allies and with other partners and allies in the Indo-Pacific about the “what-if”, the worst situation possible, and how we prepare for that. Some of that will be a public message, but a lot of that needs to be privately done.
