North Korea, South Korea, Japan and China are neighbours 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. For those keeping score at home: That means four of eight Olympic Games between 2008 and 2022 will have taken place on the Asian continent. 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.
