I find interesting that there are no women in sight. From what I read, if Royals visit Saudi Arabia the rule is separation of events for men and women. But seems the same applies when the Saudi Royals are the ones visiting other Royals' countries. Won't it be more polite to respect the Host's country the way the Royal guests respect Saudi traditions when they travel over there? I don't think the presense of the Empress in these events would have caused a major political disaster of any kind.
