Commerce was severely controlled through state trading enterprises until the end of the socialist era in 1984. Private Guinean traders can now import freely, the government having ended in 1992 its monopoly on imports of petroleum and pharmaceuticals. Prices for all goods other than imported rice and petroleum products were deregulated in 1986 and the private sector was permitted to engage in all levels of internal and external marketing. However, internal corruption and political conflicts have dissuaded foreign investment which is sorely needed to jump start commercial activity.
