I thought Mongolians were more on wealth extraction and less on economic dominance - essentially demanding tribute and after setting up an administrative class after a wholesale purge of the previous military elite the only demand being to keep the tribute flowing.

Less economic dominance because they were nomadic raiders not traders or industrialists.

Their complete cultural apathy is largely what makes them "not colonalism" technically. In the same way that samuari aren't technically feudalism because they aren't landowners but servants of a lord. Although they work by analogy pretty well.
