On 29 July 2019, Ghassan Salamé, head of the United Nations Support Mission in Libya (UNSMIL), proposed a three-point Libyan peace plan to the United Nations Security Council (UNSC), which would "require consensus in [the UNSC] and amongst the Member States who exert influence on the ground" and require Libyans "to listen to their better angels" rather than  "[fight] the wars of others and in so doing [destroy] their country."
Salamé's plan includes a truce between the Government of National Accord (GNA) and Libyan National Army (LNA) and their associated militias on Eid al-Adha, along with confidence-building measures such as prisoner exchanges, releasing arbitrarily detained prisoners and exchanging the remains of victims of the conflict; an international meeting of countries implicated in the conflict, to stop the fighting, implement the legally existing arms embargo, and promote the following of international human rights law; and a Libyan meeting similar to the originally planned Libyan National Conference.
