Ukrainian President Volodymyr Zelensky said that Ukrainian and European officials would meet at the end of the week to discuss the details of a ceasefire plan.
"It is not a plan to end the war. First of all, a ceasefire is needed," Mr Zelensky said.
"This is a plan to begin diplomacy... Our advisers will meet in the coming days, we agreed on Friday or Saturday. They will discuss the details of this plan."
Poland to reopen some border crossing with Belarus
Meanwhile, Poland will be ready to reopen two more border crossings with Belarus in November, Prime Minister Donald Tusk has said.
Poland closed its border with Belarus on 12 September as a result of Russia-led military exercises taking place in Belarus and 21 Russian drones entering its airspace on the night of 9-10 September.
The Polish government decided to reopen several rail crossings and one road crossing on 23 September.
"We will be ready this year, in November, to open two border crossings, in Bobrowniki and Kuznica," Mr Tusk said at a business event in Bialystok in eastern Poland.
"Once I settle this matter with the Lithuanians, we should open these two crossings in November, let's say on a trial basis.
"If it turns out that the border needs to be closed again, I won't hesitate for a moment."
EU chief and Nordic states confident of December accord on Russian assets
European Commission President Ursula von der Leyen and leaders of Nordic countries said they were confident that an agreement to finance Ukrainian war efforts using frozen Russian assets would be reached by December.
Danish Prime Minister Mette Frederiksen told a press conference that she "strongly" supported the idea of a "reparations loan".
"I think, to be honest, it's the only way forward, and I really like the idea that Russia pays for the damages they have done and committed in Ukraine. For me, there is no alternative to the reparations loan," Ms Frederiksen told reporters.
"What is necessary is to have a conclusion at our meeting in December so we will be able to move forward," the Danish leader said following an annual meeting of the Nordic Council, which gathers Nordic countries in Stockholm.
EU leaders last week stopped short of approving a mammoth "reparations loan" backed by frozen Russian assets.
Instead, they tasked the European Commission to move ahead with options for funding Ukraine for two more years, leaving the door open for a €140 billion "reparations loan" using frozen Russian assets.
But the plan has faced strong objections from Belgium, where the bulk of the approximately €200 billion of frozen Russian assets are held, over the legal consequences and the sharing of risks.
"It's legally a sound proposal, not trivial, but a sound proposal," Ms von der Leyen said.
"The basic message is very clear towards Russia. We're in for the long haul. We are ready to cover the financing needs of Ukraine, so that we are standing by Ukraine for as long as it takes," she added.
The proposal will be raised at an EU summit in December.
