"Russia Gave Up Ukraine, Kazakhstan, and the Caucasus." The US Declassified Transcripts of Putin's Conversations with Bush
The published transcripts pertain to three meetings between Putin and Bush that took place in 2001, 2005, and 2008, resulting from a lawsuit filed by the “National Security Archive” under the Freedom of Information Act. In the first meeting, held on June 16, 2001, at the “Brdo” castle in Slovenia, Putin raised the issue of lost territories, which also confirms his concern about this matter at the beginning of his presidency, according to a transcript made by the BBC.
