I'm not sure whether non-US research institutions are less teaching focused overall than their state-side counterparts but there are plenty of other confounding cultural factors. In Russia, for example, the most elite science/engineering university (PhysTech) isn't as well known globally as MIT or Caltech because it is made up of dozens of research institutes that publish under their own name instead of under the umbrella organization. As a result most academics dont know that all of this research is produced by a single (albeit distributed wrt geography and branding) powerhouse.
