When were the regions you mention ever part of Germany, Austro-Hungary...or even reaching back to the Holy Roman Empire of the Germanic Peoples?
If my limited knowledge of history is correct all of Ukraine was either part of the Mongol Empire or Russian Empire, unless we reach back to the time of the Original Roman Empire when the area was mostly Slavic and Celt tribes...not claimed or organized. Even the Goths settled there a while but never made an actual country of it.
All of Western Ukraine was in the Empire.
