So as to overcome the consequences of economic sanctions and war destruction to the oil sector, the decrees were adopted in 2001 by the Government of the Republic of Serbia. On December 31, 2010, the decrees were annulled which was very important for the liberalisation of the oil derivatives market. Pursuant to those decrees, oil derivatives prices were limited and special import, processing, distribution and trade conditions and procedures for oil, i.e. oil derivatives were introduced. There was also a minimum quantity of crude oil which NIS processed for other importers.
