North Korea, South Korea, Japan and China are neighbors with deep, sometimes twisted histories that get along uneasily with each other in this particular geographic cul-de-sac. The latter two, at loggerheads over North Korea's nuclear program, didn't speak, and the world watched the awkwardness. With the completion of the 2018 Pyeongchang Games, that Olympic trinity marks one-third of a noteworthy Olympic run by Asia. Japan and China will, it's likely, be highly motivated to outdo South Korea (and each other). That could be said about pretty much anything at an Olympic Games, inside the rings and out.
