The talks in Moscow aimed to halt Haftar's nine-month campaign to seize the Libyan capital, Tripoli, from forces aligned with the internationally recognised government of Fayez al-Serraj.
Since Muammar Gaddafi was toppled in 2011, the North African country has been in turmoil, with outside powers providing support to rival factions. Turkey backs Serraj's government.
"We cannot say that the ceasefire has collapsed, it's much too early for such an interpretation," Akar told reporters in Ankara, adding that Ankara was waiting for the outcome of efforts by Moscow, which has given support to Haftar.
Turkey has sent a training and cooperation team which is now active in Libya, Akar said.
President Tayyip Erdogan said on Tuesday Turkey would "teach a lesson" to Haftar if his attacks against the Tripoli-based government continued. [nL8N29J3DC]
On Sunday, Germany will host a summit on Libya involving the rival camps, their main foreign backers and representatives from the United Nations, the United States, Russia, Britain, France, China, Turkey and Italy.
