I can start, and Brian might wish to add.
The science-based approach is critical, because countries may take different views in terms of their trade policy, but the science is the science. When we found our decision-making on the science, we establish a basis of communication that is consistent across borders. It then allows us, in terms of that conversation, to focus on understanding what is demonstrated, where there may be uncertainty, and how we might measure and address any uncertainty that exists.
In the sanitary and phytosanitary sphere there's Codex Alimentarius for food safety. Its actions are based in science. In terms of animal health, there's the World Organization for Animal Health, the OIE. Again, it founds itself in the science. The same holds true in terms of plant health through the International Plant Protection Convention. We have a very solid international framework to facilitate the interaction between trading partners, and it is grounded very solidly in science because it serves as an equating consideration.
Brian, would you like to add something?
