People living in the parts of Europe that were dictatorships until ~35 years ago (everything to the east of Germany, more or less) don't like their region to be called "Eastern Europe", even though that is what everyone called it for 50 years. There was Western Europe, and Eastern Europe. But since Eastern is connotated with dictatorships, Russian occupation, poverty and things like that they've invented a new term wich is "Central Europe".

So now you'll hear people from Czechia, Slovakia, Poland, etc refer to their parts of Europe as Central, because they don't want to be called Eastern, and they especially absolutely do not want to be associated with Russia in any way. Which is completely understandable.
