Again, what I would need to understand is the relationship between sanction and results on the ground. From my viewpoint, we just don't have enough information.
We heard about two cases today, for instance. If I understood correctly, immediately I wonder why a company would block the access of a minister of environment to a UNESCO heritage site. Without a full understanding of why these situations are happening, I think it's very difficult to know what kinds of tools would best be used to address those problems.
