Perhaps I could supplement that somewhat. There are two areas where we're engaged in regulatory cooperation discussions with the United States. One is in the context of the SPP through the regulatory cooperation framework. The other is in the context of the NAFTA work plan, where we're working on sectors and looking at areas where there are ways to either share data or harmonize regulations. Right now the sector we're most active in is swine, but other sectors are being considered and there's work potential there.
The principle here is certainly not to lower regulations. Rather, where there are differences that are not making a substantial difference to the intent of the regulations...to look at those and to see if they can be modified, or whether we can recognize each other's regulations.
It's that sort of work that's under way in these two contexts.
