of crude construction materials (clays, stone, and sand and gravel) presumably
are produced, but output is not reported quantitatively and available information

DJIBOUTI 
 
 The Republic of Djibouti lies on the west side of the Bab-el-Mandeb, which
connects the Red Sea and the Gulf of Aden. Formerly the French Territory
of Mars and Isses, Djibouti received its independence in June 1977. The economy
of the country was based on the commercial and maritime activity of the port
of Djibouti and the operation of Chemen de Fer Franco-Ethiopian (CFE) which
connects the port with Addis Ababa, Ethiopia. The country continued to be
plagued by chronic unemployment and a se 
vere balance of trade deficit in both 1978 and 1979. Subsidies from France
and aid from Saudi Arabia and other Arab states helped to sustain the economy.

 Djibouti had no significant mineral production although small, unreported
quantities of crude construction materials undoubtedly were produced for
local use. The potential for production of salt, gypsum, limestone, cement,
and perlite exists but the small population (250,000) and distance from substantial
markets for these low unit
