The economy of the Democratic Republic of the Congo - a nation endowed with vast potential wealth - has declined drastically since the mid-1980s. The war, which began in August 1998, has dramatically reduced national output and government revenue, has increased external debt, and has resulted in the deaths from war, famine, and disease of perhaps 3.5 million people. Foreign businesses have curtailed operations due to uncertainty about the outcome of the conflict, lack of infrastructure, and the difficult operating environment. The war has intensified the impact of such basic problems as an uncertain legal framework, corruption, inflation, and lack of openness in government economic policy and financial operations. Conditions improved in late 2002 with the withdrawal of a large portion of the invading foreign troops. Several IMF and World Bank missions have met with the government to help it develop a coherent economic plan, and President KABILA has begun implementing reforms. Much economic activity lies outside the GDP data. Economic stability, aided by international donors, improved in 2003. New mining contracts have been approved, which - combined with high mineral and metal prices - could improve Kinshasa's fiscal position and GDP growth.
