> The Han may dominate but the country functions more like a colonial empire.

At the level of spoken language, Han natively speak several mutually unintelligible languages; even at the written level, most of the mutually intelligibility only exists in the more formal registers. Are Han really one ethnic group then? Or more like a family of closely related ethnic groups?

> Japan is something else. The description makes sense there

Are Ryukyuans the same ethnic group as Yamato Japanese?
