The pursuit of sanctions right now would risk disrupting the ongoing efforts at peace. While we have not seen anyone take the route of sanctions, we have seen some announcements from France, for example, about the possibility of military support, which have caused Azerbaijan to withdraw from planned international meetings and discussions that could have helped to advance the peace process. Whether that would have happened or not, we don't know, but it certainly provided an excuse that could be used.
Again, that type of activity—the imposition of sanctions—could risk providing excuses for some parties to the conflict to stall further on peace talks, which is obviously counterproductive.
