Mr. Gerry Liston:

There are two issues as regards tracking. There is the quantitative trade statistic-type tracking. I think the point that was made yesterday was that a lot of services are provided over Zoom or whatever, so there is nothing passing through, say, a customs authority that can quantify a volume, as in the case of goods. As regards tracking from the perspective of enforcement or identifying this type of activity, first, it is important to mention that there is also an obligation under international law on states not just to prevent this activity but to monitor it, a procedural obligation to identify the extent to which offending activity of any particular kind is going on within a state's jurisdiction.

As regards services - and this is where I might come in-----
