"We will demand that ironclad security guarantees become part of this agreement," Deputy Foreign Minister Alexander Grushko told the Russian media outlet Izvestia in remarks published on Monday.
"Part of these guarantees should be the neutral status of Ukraine, the refusal of NATO countries to accept it into the alliance."
US President Donald Trump is expected to speak to Russian President Vladimir Putin this week as military chiefs prepare to discuss peacekeeping plans in London.
The call, announced by US special envoy Steve Witkoff, comes as Putin continues to resist a US-backed proposal for a 30-day ceasefire in Ukraine.
Although Ukrainian president Volodymyr Zelenskiy has accepted the proposed unconditional ceasefire, the Russian president has said Ukraine must agree to give up its ambitions of joining NATO and cede territory to Russia before any pause in hostilities.
UK Prime Minister Keir Starmer has accused Putin of seeking to delay a ceasefire, while French president Emmanuel Macron has said the Russian president "does not seem to be sincerely seeking peace".
But on Sunday, Witkoff insisted that Putin was making "a constructive effort" and that the upcoming call with Trump showed there was "positive momentum".
Meanwhile, military chiefs from the "coalition of the willing" convened by Starmer and Macron will meet in London on Thursday to discuss plans for a Western peacekeeping force to be deployed to Ukraine in the event of a ceasefire.
Speaking to French media ahead of the online summit that the UK hosted on Saturday, Macron said the French-British blueprint doesn't aim to deploy a "mass" of soldiers in Ukraine and instead envisages stationing troop contingents in key locations.
According to La Dépêche du Midi and Le Parisien, the French president spoke of participating nations each deploying several thousand troops to "key points" in Ukraine.
Their missions could include providing training and supporting Ukrainian defences, to demonstrate long-term support for Kyiv.
Following the virtual meeting on Saturday with the leaders of 26 other nations, plus representatives from the EU and NATO, Starmer said there had been "new commitments" offered and planning would now move into an "operational phase".
But it remains unclear which nations have committed troops to a peacekeeping operation, while several have suggested such talks are premature given the lack of a ceasefire.
Putin is also likely to object to any agreement that involves European or NATO troops being stationed in Ukraine, although Zelenskiy sees this as essential to deterring future Russian aggression.
Meanwhile, the fighting continues, with Ukraine said to be under increasing pressure in the eastern Donetsk region, part of which has been under Russian control since 2014.
Ukrainian troops are also reported to be in retreat in the Kursk region of Russia, which they seized in a surprise raid in August in an attempt to secure a bargaining chip for future negotiations.
