The Soviet ruble was not internationally convertible and the government was desperate for foreign hard currency to buy goods and services from abroad and government exchanged it at fixed prices which often wasn't fair. The Beryozka shops were an efficient source of this currency.
One chain belonged to the Vneshposyltorg (Foreign Mail Order Trade) and was intended for Soviet citizens who were paid some of their salary in foreign currency or received remittances from relatives or friends abroad. The foreign currency had to be exchanged for ruble-denominated Vneshposyltorg cheques, either by the recipient or by government intermediaries.
The other chain sold goods directly for foreign currency and for Vneshtorgbank series D cheques. Only foreigners and Party apparatchiks were allowed access to these shops.
Initially the shops only carried the Beriozka branding in the territory of the RSFSR and Kazakhstan. In other republics of the Soviet Union different "national tree" names were used. For example, in the Ukrainian SSR they were called Kashtan (chestnut), Ivushka (a tender diminutive for "iva", willow) in the Byelorussian SSR, Chinara (Oriental plane) in the Azerbaijan SSR, and Dzintars (amber) in the Latvian SSR. Eventually all of these shops rebranded under the Beriozka name. Beriozka stores were present only in the major cities, most prominently Moscow.
There were also separate Albatross stores in Soviet port cities, such as Vladivostok, that sold goods to Soviet sailors returning from abroad. The Albatross stores sold goods for Torgmortrans cheques issued to the sailors by the Merchant Maritime Transport department (Torgmortrans) of the Soviet Ministry of the Maritime Fleet in exchange for foreign currency earned by the sailors.
Beriozka stores were opened in 1964. Their predecessors were Torgsin stores of the 1930s and the highly ineffective Vneshposyltorg departments of the large Soviet department stores (e.g. State Universal Store) that allowed catalog mail order from abroad by customers paying in hard currency.
Beriozka stores became obsolete in the early 1990s when the ruble became convertible with other currencies. The stores were privatized and in the mid-1990s most were closed as uncompetitive.
Many other socialist countries had similar retail chains, such as Intershops in the German Democratic Republic, Tuzex in the Czechoslovak Socialist Republic, Comturist in the Socialist Republic of Romania, Corecom in the People's Republic of Bulgaria, Pewex in the Polish People's Republic, Dollar stores in the Republic of Cuba and Friendship Stores in the People's Republic of China,[3] though some of these systems allowed anyone with foreign currency to shop there.
