Germany (or rather "Prussia", given that unified Germany is relatively new thing) and Russia had been much more friendlier with each other than their relationship with Poland, for considerable stretches of history. To the point that at times it's talked as "traditional german-russian friendship".

On completely unrelated note is that our (Polish) current government is beyond stupid, voided long-term contracts during a period of cheaper gas prices, and is now forced to buy at spot prices for more than it saved on the long-term contract (also lots of political capital being involved between govt and opposition).
