It happens only rarely. It depends which level of sanctions you're talking about. At the UN level, traditionally what we've seen is that the majority of the sanctions list is composed of designations on North Koreans themselves. That may include North Koreans who operate abroad, but it tends to focus on North Korean parent companies, North Korean diplomats, and so on. Rarely at this stage do you see the UN designating a non-North Korean national facilitator. It has happened, but it's less frequent than the designation specifically on North Koreans. When you turn to the U.S. national level, or EU level, for sanctions, it's a different picture.
