UNSC Resolution 1132 (1997) was adopted on 8 October 1997, demanding that Military Junta relinquish power and restore the democratically elected Government. The resolution imposed a ban on the sale or supply to Sierra Leone of petroleum and petroleum products and arms and related materiel of all types, including weapons and ammunition, military vehicles and equipment, paramilitary equipment and spare parts for those items. It also set up a Security Council Committee.
UNSC Resolution 1156 (1998) adopted on 16 March 1998, immediately terminated the prohibitions on the sale or supply to Sierra Leone of petroleum and petroleum products referred to in para. 6 of U.N.S.C. Resolution 1132 (1997), in light of the return of the democratically elected President.
UNSC Resolution 1171 (1998) adopted on 5 June 1998, terminated the general ban on the sale or supply arms and related materiel. Instead a specific ban on arms and related materiel of all types, including weapons and ammunition, military vehicles and equipment, paramilitary equipment and spare parts for those the aforementioned, to Sierra Leone other than to the Government of Sierra Leone through named points of entry was introduced. The only exemption to this is sale or supply of arms and related material for the sole use in Sierra Leone of the Military Observer Group of the Economic Community of West African States (ECOMOG) or the United Nations.
UNSC Resolution 1940 (2010) adopted on 29 September 2010 terminated with immediate effect the remaining sanctions measures imposed on Sierra Leone and dissolved the Sierra Leone Sanctions Committee established by paragraph 10 of resolution 1132 (1997).
