[Sci-Fi In General] Is there any sci-fi that shows national colonization?

  To elaborate, alot of sci Fi depends on earth either being under one nation, or a global alliance that might as well be one. Is there any sci Fi that explores say china, and the US competing over colonies in the galaxy? Or just other planets that have been colonized having multiple borders. It never struck me right that, ok take for example let's say there's this earth like planet called Bob. Bob has multiple continents, and supports a colony of a couple billion people. Wouldn't it make more sense that Bob would eventually split up into multiple countries rather than form one homogeneous planetary government?

In "For All Man Kind" colonization of the Moon and Mars is a competition between the US and USSR.

In the Civilization video game series, one common win condition is to explicitly engage in national colonization before any other nation.

Stargate SG-1, has humans on other planets while Earth remains divided.
