<P> Inefficiency and corruption of Sierra Leone's institutions are impeding its economic growth . Absence of well - established institutions is the result of the destructive civil war which ended only in 2002 . World Bank's assistance brought reforms but also allowed local government to become lax . The Ministry of Mineral Resources (Sierra Leone) (MMR) administers the regulations and property rights of the Mines and Minerals Act (Sierra Leone) in 2009 . However, licences made by mining companies were only published in 2011 . </P> <P> This reflects inefficiency in establishing a legal framework due to time - lag . It is also questionable whether there are proper corruption - checking mechanisms . Although the Sierra Leone Anti-corruption Commission (ACC) investigates corruption cases, critics have that noted it could merely be a political tool to quieten the government's political opponents . However, the ACC objects to this and claims it is impartial . Pervasive corruption and unstable political environment stymie Sierra Leone's economic growth and decrease investors' confidence in Sierra Leone's business and political climate . </P> <P> Policies regarding well - management of mining industry should be done alongside a broader focus for the economy's development, and greater efforts should be done to expand the manufacturing and service sector, which currently only contribute 12% to the GDP . Sierra Leone produces raw diamonds but gem - quality diamonds are manufactured in developed countries like Belgium . For example, the government of Sierra Leone can provide greater tax incentives for investors to conduct businesses and invest in Sierra Leone, to facilitate the transfer of technology and skills to the native workers . One recent example is the Gemstone School Sierra Leone, which was established as an institution to improve diamond polishing, cutting and jewelry - manufacturing skills to boost job - training and employment opportunities locally and to attract overseas investors . </P> <P> More efforts from the government and Multi-National Corporations can hence be done in the future to build more diamond - processing facilities and plants in Sierra Leone to boost the diamond mining industry . </P>
