1992 Russia offered Kaliningrad to both Poland and Lithuania, but neither country was interested in a region with seriously underdeveloped economy and inhabited by Russians who wouldn’t feel either Polish or Lithuanian, nor would they speak the language.
Interesting -- I haven't heard about this. Do you know where I can find out more about this offer?
I have spent some time in the summers of 1993-1995 in Lithuania near the border with Kaliningrad on the Curonian spit. I believe the Russian fleet was still based in Klaipeda in 1994.
