During the Second Congo War mass-scale looting of mineral assets by all combatant forces—Congolese, Rwandan, Ugandan and foreign civilians—took place. The small artisanal mining operations the fighters were robbing sometimes shut down afterwards and larger foreign businesses reduced operations as well. Following the peace accord in 2003, the focus returned to mining. Rebel groups supplied international corporations through unregulated mining by soldiers, locals organized by military commanders and by foreign nationals. The political framework was unstable. In 2009 the DRC signed a loan contract with the International Monetary Fund (IMF) for $12 billion of debt relief in 2010. The loan included trade conditions, such as liberalization of the diamond trade. At the end of 2012 the IMF suspended the last payments, because of a lack of transparency in the DRC's process for awarding mining contracts. The mining sector has since expanded, but commodity prices have declined and this has hampered the DRC's progress.
