Every country is obliged to fully comply with Security Council resolutions in the imposition of sanctions. In many cases, some countries simply don't have the capacity to do what can be a very complex and difficult thing. Countries like Canada and others offer support to those countries, so that they can fulfill their obligations. In some cases, there are countries that may not wish to. We're bringing diplomatic pressure on those who have the means to but may not be fully using those means.
You know, with 200 countries in the world, there's a lot of work that can continue to be done to make sure that the compliance regime is solid.
