Look at the ages of the North Korean women involved.
There are reasons why, with some important exceptions, American female television reporters and anchors are likely to have their on-camera careers end at a fairly young age unless they are lucky enough to keep a youthful appearance. By contrast, Asian media and viewers continue to place a priority on maturity and experience, which means older Asian women may continue to get selected for on-air coverage of important events. That's not just true in North Korea but throughout Asian media.
I'm married so I am not going to get into discussing the relative attractiveness of specific women. Also, beauty is obviously in the eye of the beholder. However, as a general rule, I think it's pretty clear that Korean women often meet Western standards of attractiveness, and Korean women often age better than their Western sisters.
I don't think going beyond that generic statement would serve a valid purpose — we're on a conservative discussion site, not a “rate her hotness” site — so while physical attractiveness is a legitimate job requirement of broadcast media and one I don't mind discussing, it's not a subject I want to discuss in detail about specific women in media.
If I give my opinions on which races are hot and which are not, I’ll get banned again.
