Kazakhstan has attracted $330 billion in foreign direct investment (FDI) from more than 120 countries since its independence. According to the US State Department, Kazakhstan is widely considered to have the best investment climate in the region. In 2002 the country became the first sovereign in the former Soviet Union to receive an investment-grade credit rating from an international credit rating agency. Foreign direct investment (FDI) plays a more significant role in the national economy than in most other former Soviet republics.
