Passage: Economic reform efforts continued with the support of international organizations, notably the World Bank and the International Monetary Fund. The reform program came to a halt in June 1997 when civil war erupted. When Sassou Nguesso returned to power at the end of the war in October 1997, he publicly expressed interest in moving forward on economic reforms and privatization and in renewing cooperation with international financial institutions. However, economic progress was badly hurt by slumping oil prices and the resumption of armed conflict in December 1998, which worsened the republic's budget deficit.
What organization never supported economic reform efforts?
