Russian and Ukrainian negotiators agreed that a permanent ceasefire in eastern Ukraine must be observed "unconditionally" following hours-long talks in Paris on Wednesday,Eurasia Diary reports citing CNN 

The announcement came after a meeting at the Elysee Palace of the so-called Normandy Format -- a four-way conversation between representatives from Ukraine, Russia, Germany and France -- that has been trying to broker peace in eastern Ukraine since 2014.

Tensions between Moscow and Kyiv are at their highest in years, with a large Russian troop build-up near the shared borders of the two former Soviet republics -- spurring fears that Russia could launch an invasion.

Speaking after Wednesday's meeting, Moscow's chief negotiator Dmitry Kozak said the ceasefire must be observed "unconditionally" but that many other issues in eastern Ukraine remained unresolved.

Western officials are continuing to push for a diplomatic solution to the tensions through the full implementation of the Minsk agreements -- a ceasefire protocol signed by Ukraine and Russia in 2015.

"We agreed that regardless of different discrepancies of the Minsk agreements that exist between Ukraine and the Donetsk and Luhansk regions, the truce in Donbas must be observed unconditionally," Kozak said.

He added that the "obligation" to implement such agreements "lies with the armed forces of Ukraine and the armed formations of the (eastern separatists) Donetsk People's Republic and Luhansk People's Republic."

Ukrainian negotiator Andriy Yermak said all parties were in support of a permanent ceasefire and Ukraine was ready to negotiate around the clock to prevent war and to de-escalate tensions around the border.

Yermak called the renewal of the Normandy Format talks -- first held after Russia's 2014 invasion of Crimea -- a "very positive signal" and the first such substantive agreement since the end of 2019.

He called talks "really substantial, but not an easy discussion" and while there were still disagreements there was an interest in working through them.

"The work continues and I can tell you that Ukraine as usual is ready to negotiate, to meet 24-7. Because for us, for (Ukrainian) President (Volodymyr) Zelensky, for the entire team, the goal of stopping the war, of ending the war and returning our territories -- and today that this also includes easing the tensions -- the de-escalation around the Ukrainian border, is the priority," Yermak said.

Kozak and Yermak said the talks would resume in about two weeks in Berlin.
