Ukraine is unfriendly business environment for Poles nowadays. Mind that there are special tariffs for bribes for us there! I mean a Ukrainian official takes $100 from a German entrepreneur, say, and if he faces a Pole he just makes the cost twice bigger and that is $200! That's their logic!
Well, once you come across some fan of their nationalistic icon Stephan Bandera (there are many such dorks among the Ukrainian well-positioned officials) you should expect nothing good. Get ready he'll try to humiliate you and treat you just as if you were an outcast! He won't shake hands with you or offer you a seat. Ye, it's going on exactly this way in Ukraine now. When I saw Bandera's portrait on the wall of the office there I had no illusions from the very start!
Actually I was involved in growing raps crops in Ukrainian fields and I found myself on the rocks finally. I turned to the International union of Polish businessmen in Ukraine for help, all in vain! They only advised that I should curtail my business and make a try somewhere else.... Their argument was that "only very wealthy Poles may afford business in the Ukraine"!
