The UN Security Council has asked the Secretary-General to study the role played by the United Nations peacekeeping mission in resolving conflict in Liberia.
The UN Mission in Liberia closed last month after nearly 15 years during which the country was at civil war for 14 years.
Earlier this year President George Weah succeeded Ellen Johnson Sirleaf in what is described as the first peaceful transfer of power between democratically elected leaders in 71 years.
A peace and national building plan submitted by the UN Secretary-General will continue to be implemented in partnership with the Liberian government.
