Kazakhstan, geographically the largest of the former Soviet republics, excluding Russia, possesses enormous fossil fuel reserves and plentiful supplies of other minerals and metals, such as uranium, copper, and zinc. It also has a large agricultural sector featuring livestock and grain. In 2002 Kazakhstan became the first country in the former Soviet Union to receive an investment-grade credit rating. Extractive industries have been and will continue to be the engine of Kazakhstan's growth, although the country is aggressively pursuing diversification strategies. Landlocked, with restricted access to the high seas, Kazakhstan relies on its neighbors to export its products, especially oil and grain. Although its Caspian Sea ports, pipelines, and rail lines carrying oil have been upgraded, civil aviation and roadways continue to need attention. Telecoms are improving, but require considerable investment, as does the information technology base. Supply and distribution of electricity can be erratic because of regional dependencies, but the country is moving forward with plans to improve reliability of electricity and gas supply to its population. In 2010 Kazakhstan joined the Belarus-Kazakhstan-Russia Customs Union in an effort to boost foreign investment and improve trade relationships.
