The geography of Bosnia and Herzegovina is mountainous. The government system is an emerging federal democratic republic.

Formally a planned economy, Bosnia and Herzegovina is transitioning to a mixed economic system which includes a private-enterprise system, combined with government regulation. Bosnia and Herzegovina is a member of the Central European Free Trade Agreement (CEFTA).
