According to the UN, more than 20,000 foreign mercenaries and military personnel are still in Libya. They include fighters from Turkey, Russia, Sudan and Chad.
Also up for discussion is the creation of unified security forces for the North African country.
How did it come to this?
Libya was thrown into a decade of violence following the 2011 overthrow and eventual killing of longtime dictator Moammar Gadhafi.
Warring factions essentially split the country, with the UN-recognized Government of National Accord (GNA), led by Prime Minister Fayez Sarraj, controlling the capital, Tripoli, and and Khalifa Haftar, the commander of the self-styled Libyan National Army (LNA) controlling the east.
Berlin hosted the first round of the UN-sponsored talks on January 19, 2020, in a bid to end hostilities.
Both Sarraj and Haftar were in Berlin during the period but refused to sit or meet with each other as tensions remained between the two parties. Envoys from the US, Russia, China, the UK, France, Italy, the EU and the UN also attended.
