World powers are gathering Wednesday in Berlin to seek lasting peace in Libya by ensuring the conflict-wracked North African country stays firmly on the path toward general elections on December 24.

Representatives of Libya's interim government will join US Secretary of State Antony Blinken as well as the foreign ministers of France and Egypt at the UN-sponsored talks.

The efforts to end a decade-long spiral of violence in Libya would be the second round in Berlin, after the first attended by the presidents of Turkey, Russia and France in January 2020, before the pandemic.

Ahead of the talks, host German Foreign Minister Heiko Maas reminded participants of pledges made in 2020 for an end to international meddling and for foreign militants or troops to withdraw.

"Those who promised to withdraw last time in Berlin have not kept their word," said Maas in an interview with Die Welt daily.

"But for the Libyans to determine the fate of their country again, the foreign forces must leave. The transitional government has also made that clear," Maas stressed in the interview.

The United Nations has estimated that 20,000 foreign fighters and mercenaries are still on Libya's territory. And that presence is seen as a threat to the UN-backed transition leading to the elections.

The oil-rich country descended into chaos after Libya's former leader Muammar Gaddafi was toppled and killed in a 2011 NATO-backed uprising, resulting in multiple forces vying for power.

In October, after Turkey-backed forces of the Government of National Accord based in Tripoli routed those of eastern military strongman Khalifa Haftar, the two camps agreed a cease-fire in Geneva.

The security situation in Libya has been slowly improving since. However, the UN recently warned that progress has stalled, notably on a key requisite of the polls - the pullout of all foreign soldiers.

Western leaders have repeatedly called on the foreign fighters to depart. 

But Russian mercenaries supporting Haftar's side in the east of the country are still in place.

Turkey meanwhile has troops in Tripoli, which it argues were sent under a bilateral agreement with the government, implying that they are not affected by a request for foreign troops to leave. But any withdrawal is also a delicate balancing act, said the German foreign minister.
