Sometimes I feel like Beijing Hans and Muscovite Russians have very similar development.
Southern Slavics, for example, Ukrainians consider themselves as real Rus'- Kievan Rus. Muscovites are mixture of Tatar-mongols.
Both has impreial ambition which directly inherited from Mongols
There is not that much evidence of Mongolian admixture in Russians...check some genetic tests. There is far more Slavic admixture with Finno-Ugric tribes that were absorbed as the Eastern Slavs moved further East and consolidated into major political entities.

which tells me that Slavic men did not except mixed race people with non-Slavic fathers in Russia proper. It is true that "Ukrainians SAY" they are more pure and that the Russian people are an offshoot of them (Kievan Rus) but in reality Kievan Rus was started by the Vikings and although it is true that parts of Western Ukraine (and Belarus) were not controlled by Mongolians or Turkic tribes they have long been considered "rednecks" by Russians who have constantly been passed around between Russia, Latvia, and Poland.
Both groups have some admixture with non-Slavs...from Europe and Asia, but I seriously doubt Russian imperial ambitions have much to do with Mongolians. They seemed to be on their way to that before Mongolians controlled them. Like China the Russians were probably motivated for expansion to increase trade and to have defensible borders against Eastern Nomads and Western threats like the Poles, Swedes, and other European incursions. They also considered themselves the 3rd Rome, after the fall of the Byzantine Empire, because they then became the leading Orthodox Power...this position gave them an excuse (or obligation) to interfere in other Orthodox peoples (especially Slavs) affairs on their behalf.
As far as China, it is hardly fair to say that the only imperialistic or expansionist Han were Northern Chinese around Beijing who mixed with Northern nomadic Mongols.

In this way Russia and China are similar in that there is little genetic differences in Han males in North and south, the difference is in the females.
Or it could have been enough Han Northern males have migrated South over the last 1,500 years to mitigate any real difference.
