China and Ukraine

[Belacqua]

Sometimes a person's native language is used like an ethnicity. So Russian-speakers in territory claimed by both Ukraine and Russia generally feel themselves to be Russian. 

If Russia wants to reclaim authority over the areas where the majority of people speak Russian, it is not "killing Ukrainian." No effort is being made to wipe out the language.

then, Moscow did not destroy languages, but poorly united them

I don't quite understand what you mean by this.

A lot of countries have people who speak different languages. Sometimes, as in Switzerland, it works out. Other times people feel divided from each other based in part on language. 

Ukraine, as you probably know, has a fairly complicated history. When a country's parts keep changing, it's understandable that different language groups will be swept up together.
