Yeah, I think the concept might be mapping them so there's some kind of scale proportion between the countries their NA equivalent, as well as a climate one. There's still some misses, though. I'm not sure how "Eastern Europe" compares to the continental divide, and Ukraine has got to be larger than Japan.
To be fair, there aren't a lot of areas around that size in the world with deserts, jungles, and monsoons. It's a pretty good comparison, as much as it's possible for there even to be one between regions that large.
Kansas, Missouri, and Tennessee don’t really have the same climate as the sun belt states either so I was taking it as the climate in northern china vs SE china
