After the death of Joseph Stalin, Nikita Khrushchev offered the Kaliningrad Oblast to the Lithuanian SSR. Secretary Antanas Sniečkus refused this offer. In 2010, a secret document was found which indicated that in 1990, the Soviet leadership was prepared to negotiate the return of Kaliningrad to Germany against payment. The proposal was declined by German diplomats. After the dissolution of the Soviet Union, the Kaliningrad Oblast has become an exclave of Russia. Lithuania, Germany, and Poland lay no official claims to the region at this time.
