The presidents of Russia, Turkey and France were among global chiefs signing up to the agreement to stop interfering in the war – be it through weapons, troops or financing, AFP reported.
But the talks failed to deliver "serious dialogue" between the warring parties – strongman Khalifa Haftar and the head of Tripoli's UN-recognized government Fayez al-Sarraj – or to get both sides to sign up to a permanent truce.
"Ensuring that a cease-fire is immediately respected is simply not easy to guarantee," said summit host Chancellor Angela Merkel.
"But I hope that through today's conference, we have a chance the truce will hold further."
US Secretary of State Mike Pompeo acknowledged that there are "still some questions on how well and effectively" the commitments can be monitored.
But he said he is "optimistic that there will be less violence and... an opportunity to begin the conversation that (UN special envoy) Ghassan Salame has been trying to get going between the Libyan parties".
Libya has been torn by fighting between rival armed factions since a 2011 NATO-backed uprising killed former leader Muammar Gaddafi.
Most recently, Sarraj's troops in Tripoli have been under attack since April from Haftar's forces.
Clashes have killed more than 280 civilians and 2,000 fighters and displaced tens of thousands, until a fragile cease-fire backed by both Ankara and Moscow was put in place on January 12.
Although Sarraj's government is recognized by the UN, powerful players have broken away to stand behind Haftar – turning a domestic conflict into what some have described as a proxy war in which international powers jostle to secure their own interests.
Alarm grew in recent weeks after Turkey ordered in troops to shore up Sarraj's Tripoli-based Government of National Accord (GNA).
UN chief Antonio Guterres said the world powers had made "a strong commitment to stop" the conflict escalating into a regional confrontation.
Russian Foreign Minister Sergei Lavrov pointed to some positive takeaways from the talks, but said the summit failed to launch necessary talks between Sarraj and Haftar.
"It is clear that we have not yet succeeded in launching a serious and stable dialogue between them," Lavrov told reporters after the conference, where Haftar and Sarraj did not meet face to face.
Nevertheless, the Libyan parties had taken "a small step" forward, Lavrov added.
Pro-Haftar forces upped the ante on the eve of the talks by blocking oil exports at Libya's key ports, crippling the country's main income source in protest at Turkey's decision to send troops to shore up Sarraj.
The flaring oil crisis underlined the devastating impact of foreign influence in the conflict, in which Sarraj's GNA is backed by Turkey and Qatar while Haftar has the support of Russia, Egypt and the United Arab Emirates.
The European Union will discuss all ways to uphold the formal cease-fire in Libya but any peace settlement will need real EU support to make it hold, the EU’s top diplomat Josep Borrell said on Monday.
Asked about whether the EU could consider a military peace-keeping mission, Borrell said, “A cease-fire requires someone to take care of it. You cannot say, ‘this is a cease-fire’ and forget about it ... Someone has to monitor it, to manage it.”
