Jeezus you're dense. Short answer is that most of the world is impacted by, and therefore acutely interested in, what is going on with what is still really the only 800 pound gorilla of nations on this planet.
Suppose down under that they're not REALLY interested in what's up with China too?
If you weren't so interested in a cheap shot..... nah, never mind, you still wouldn't have gotten the point.
