The first thing I would say is that the statements we've been producing have been a fantastic initial effort. What we're saying very much is to build on that and take them to the next level. Those statements, at the end of the day, are not legally binding on the countries that make them, so I think the next level up is to say that we've agreed to this in principle as a statement, and now let's actually put our money where our mouth is and put some legal text in writing that we as a country would be willing to abide by in an international legal treaty sense.
What I think that would specifically look like is to make it much tighter around the justified grounds for countries to use export restrictions that would prohibit the production of, say, PPE from leaving a particular jurisdiction. Certainly, what we have seen in the current context is that under our current trade deals, there's a very wide berth to interpret what public health and national security grounds actually mean, and there's a scope, we feel, to begin to make that much tighter and more narrowly defined.
