It is both the capital and largest city of the Republic of Abkhazia, a partially recognised state that most countries consider a part of Georgia. The city has been controlled by Abkhazia since the Abkhazian war in 1992–93. The city, which has an airport, is a port, major rail junction and a holiday resort because of its beaches, sanatoriums, mineral-water spas and semitropical climate. It is also a member of the International Black Sea Club.
