Azerbaijan is in the Caucasus Mountains, bordered by Russia to the north, Georgia and Armenia to the west, and Iran to the south. It became an independent country in 1991 when the Soviet Union collapsed, and the post-Soviet era has included a difficult transition to democratic government, the challenge of corruption, and a difficult relationship with Azerbaijan’s neighbor Armenia. Azerbaijan’s largest industry is energy. It exports petroleum to many European countries and to China, Israel, and India. Natural gas has also become an important export in recent years. Efforts are underway to diversify the economy to be less dependent on hydrocarbons, with agriculture, tourism, logistics, and information technology being focuses of this effort.
