Lets look at the Powerpoint. When it comes to "关注", meaning "to follow something closely", and "关切", meaning "to be deeply concerned by something", the two aren't appropriate for exactly the same diplomatic scenarios, "关注" stresses seeing something as important, for example, it's appropriate to use "关注" with escalating tensions in the Middle East; whereas "关切" emphasises caring about something, for example, it's appropriate to use "关切" when there is a threat to the lives or property of Chinese people living abroad in a country where a conflict is underway.
