The Ukrainian president said his delegation is set to hand Kyiv's proposal to Washington in the "near future", ahead of talks between European leaders over the plan next week.
But they will comes after Mr Trump called European leaders "weak" and criticised them for failing to end the war between Russia and Ukraine.
As it happened: Soldier who died in Ukraine pictured for first time
Meanwhile, tributes have come in for Lance Corporal George Hooley, a 28-year-old paratrooper who died on Tuesday while observing Ukrainian forces testing a new defensive capability away from the frontline.
The MoD said he joined the army in November 2015 and was regarded as "an exceptional soldier and an impressive junior leader with extensive operational experience".
In a statement released through the ministry, Lance Corporal Hooley's commanding officer said that the paratrooper had had an "incredibly bright" future in the Parachute Regiment.
"I have no doubt that he would have continued to perform at the very front of his peer-group over the coming years," they added.
"All members of The Parachute Regiment mourn his loss; however, our sorrow is nothing compared to that being felt by his family, our thoughts and prayers are with them at this incredibly difficult time."
'If you met George Hooley, you remembered it'
The company commander added: "If you met George Hooley, you remembered it." They said the paratrooper had a "rare gift" and was a "model of professionalism".
Britain's Defence Secretary John Healey said the Lance Corporal "served our country with distinction and professionalism" and was "an exceptional soldier who will be very deeply missed".
"The tributes that have been paid to him are a testament to his exceptional attitude and ability," Mr Healey said. "George's tragic death reminds us of the courage and commitment with which our outstanding armed forces serve every day to protect our nation."
Zelenskyy: Ukraine to share peace plan in 'near future'
Mr Zelenskyy said that Ukraine was finalising a 20-point peace document to share with the United States.
"We are working very productively to guarantee future security and prevent a recurrence of Russian aggression," he said.
But Mr Trump had accused Mr Zelenskyy of not reading the original American-backed version of the peace proposal, and in an interview with Politico on Tuesday, claimed the Ukrainian president was "using war" to avoid holding an election.

Later on Wednesday, Mr Zelenskyy said Kyiv's peace delegation held a "productive conversation" with the US, and "discussed key issues for recovery, various mechanisms, and visions of reconstruction".
Prime Minister Sir Keir Starmer, German Chancellor Friedrich Merz and French President Emmanuel Macron also spoke with the US president by phone on Wednesday.
In Ukraine shelling at a hospital in the occupied southern Kherson region killed three medical workers and injured two others, according to a governor installed by Russia.
And on Wednesday morning, Ukraine said its energy infrastructure had been targeted by Russian drone strikes in the southern Odesa region.
President Trump confirmed the operation at a meeting with business leaders at the White House on Wednesday.
"We've just seized a tanker on the coast of Venezuela, a large tanker, very large, largest one ever seized, actually," he said at the start of the meeting.
Without giving additional information on the operation, Mr Trump added that "other things are happening". Later, he said that the tanker was "seized for a very good reason".
It marks the latest escalation from the Trump administration, which has in recent months ramped up pressure on Venezuelan President Nicolas Maduro.

Later, US attorney general Pam Bondi shared a video of the operation, confirming that the FBI, Homeland Security, US Coast Guard, and Department of War were involved.
She said on X that the US forces "executed a seizure warrant for a crude oil tanker used to transport sanctioned oil from Venezuela and Iran".
"For multiple years, the oil tanker has been sanctioned by the United States due to its involvement in an illicit oil shipping network supporting foreign terrorist organisations," she added.
"This seizure, completed off the coast of Venezuela, was conducted safely and securely-and our investigation alongside the Department of Homeland Security to prevent the transport of sanctioned oil continues."
She did not name the vessel, what flag the vessel sailed under, or exactly where the incident took place.
UK maritime risk management group Vanguard said that the tanker Skipper - which the US sanctioned for alleged involvement in Iranian oil trading under the name Adisa - was believed to have been seized.
On 2 September, the White House posted on X that it had conducted a strike against so-called "narcoterrorists" shipping fentanyl to the US, without providing direct evidence of the alleged crime.
Sky's Data & Forensics unit has verified that in the past four months since strikes began, 23 boats have been targeted in 22 strikes, killing 87 people.

Meanwhile, at a rally before a ruling-party-organised demonstration in Caracas, Mr Maduro did not address the seizure, but told supporters that Venezuela is "prepared to break the teeth of the North American empire if necessary".
Flanked by senior officials, he said that only the ruling party can "guarantee peace, stability, and the harmonious development of Venezuela, South America and the Caribbean".

The seizure comes after Mr Trump suggested that the US could strike Venezuela on land.
Speaking to Politico on Tuesday, he declined to comment on whether US troops would enter the country, but said that Mr Maduro's "days are numbered".
According to Bloomberg, the Maduro government describes US actions as a grab for Venezuela's oil reserves - among the biggest in the world.
Prosecutors said Sharaz Ali, 40, was "motivated by jealousy and fuelled by drink and drugs" when he set fire to Bryonie Gawith's home early on 21 August last year.
Jurors heard that Ali went to the home in Westbury Road, Bradford, aiming to "take revenge" on his ex, Antonia Gawith, who was staying there after ending their "abusive" seven-year relationship earlier that month.
Antonia Gawith managed to escape, but Bryonie Gawith, 29, and her children Denisty Birtle, nine, Oscar Birtle, five, and 22-month-old Aubree Birtle died in the blaze.
Ali told a jury he had no intention of harming others when the house went up in flames, saying: "I didn't want to hurt anyone but myself."
But after a trial at Doncaster Crown Court, he was found guilty of four counts of murder and attempting to murder Antonia Gawith.
Calum Sunderland, 26, who went with Ali to the house and kicked the door in for him, was found guilty of the manslaughter of Bryonie Gawith and her three children, but cleared of the more serious charges of murder.
He was also cleared of attempted murder, and an alternative count of attempting to cause grievous bodily harm, in relation to Antonia Gawith.
Mohammed Shabir, 45, who had also been due to go on trial, died of a heart attack in October after collapsing in prison.
Reading a statement on behalf of her family outside court, Antonia Gawith said her sister, nieces and nephew's futures have been "stolen".
"Even with justice, nothing will ever make this right," she said.
"Nothing will ever fill the silence where their laughter should be. Nothing will ever bring back our family.
"We will forever carry this brokenness, and yet we will hold on to them tightly in only ways we can now, through our memories, our photos and our precious videos. Those are all we have left now."
After the verdicts, the judge, Mr Justice Hilliard, thanked jurors and said the case had been "distressing beyond measure - three children and their mother murdered".
"I don't think anyone who heard Antonia's desperate cries for help will ever forget them," he said.
"These are truly dreadful crimes."
The judge also praised the "extraordinary bravery" of those who tried to save the children trapped in the house.
Ali and Sunderland, a convicted arsonist, were driven to the house by Shabir, stopping on the way to fill a seven-litre canister with petrol, the court heard.
Doorbell footage captured Ali telling Sunderland, who was carrying the petrol and a lighter, to "kick the door in", which he did before running back to the car.
Antonia Gawith said she saw an "angry" Ali run into the house and begin pouring petrol on her while shouting before setting himself and the house on fire.
'I couldn't save them'
In a video interview played to jurors, she sobbed as she told police how she "couldn't save" her sister, nieces and nephew, as she tried frantically to get back in the house through the back door.
"I was just screaming, trying to get back in the house and I couldn't get in. I couldn't save them," she said.

West Yorkshire Police's Detective Chief Inspector Stacey Atkinson said: "Bryonie and her three children would still be alive today if it wasn't for the horrific and truly callous actions of Ali and Sunderland that day.
"They left a mum and her three children completely helpless whilst her sister and their auntie watched on in horror.
"Our thoughts and sympathies are with the family, who despite their immense strength of character now face the rest of their lives without them."
Senior Crown Prosecution Service prosecutor Amanda McInnes said Ali was a "selfish killer who had no regard for anyone but himself".
"He was motivated by jealousy and his actions have now needlessly robbed a family of their loved ones," she said.
"Both men played their role and caused the deaths of a young family who should still be with us today."
Machado isn't the first Nobel Laureate unable to attend, but her journey to Oslo was unprecedented in the history of the prestigious prize.
Her departure from Venezuela, carried out amid heavy secrecy and probably with covert US help, was fraught with risk, but on Wednesday she was en route to Norway, where she is expected to land late in the evening.
Reports suggested she first travelled by boat to the Caribbean island of Curaçao before getting a private flight via the US. Two US F-16 jets were tracked in the skies close to Curaçao late Tuesday night.
In a phone call with members of the Nobel Institute, released just after she took off, Machado said she was "very sad" not to make it in person but "as soon as I arrive, I will be able to embrace all my family and children."
In her absence, her daughter Ana Corina Sosa Machado, whom she hasn't seen for almost two years, collected the award in Oslo City Hall and delivered the speech her mother wrote.
She spoke about 2,500 people who had been "kidnapped, disappeared or tortured" under Venezuelan president Nicolas Maduro's government and slammed the corruption that has brought Venezuela, once one of the world's richest nations, to its knees.
"This prize carries profound meaning; it reminds the world that democracy is essential to peace.
"More than anything, what we Venezuelans can offer the world is the lesson forged through this long and difficult journey - that to have democracy, we must be willing to fight for freedom."
To a standing ovation from an audience that included several South American leaders, Machado thanked the people of Norway and sent a message to her fellow countrymen and women, many of whom had travelled to Oslo from their homes outside Venezuela.
"Venezuela will breathe again," her daughter read.
"We will open prison doors and watch thousands who were unjustly detained step into the warm sun, embraced at last by those who never stopped fighting for them.
"We will see our grandmothers settle children on their laps to tell them stories not of distant forefathers but of their own parents' courage.
"We will hug again. Fall in love again. Hear our streets fill with laughter and music. All the simple joys the world takes for granted will be ours."
Ms Machado is the leader of a grassroots political movement fighting for democracy in Venezuela.
She was banned by Nicolas Maduro from running for election, so she rallied a campaign behind a little-known veteran diplomat Edmundo Gonzalez.
She organised and trained more than a million volunteers to monitor elections in 2024 and collect data.
Those results, smuggled out of the country, were verified by independent experts and confirmed a landslide win for Gonzalez and Machado's party.
Maduro refused to recognise the result and detained thousands of opponents.

Protests have failed to dislodge him, although US president Donald Trump has stationed a massive naval force off the coast and has warned the Venezuelan leader his "days are numbered".
Mr Trump had lobbied publicly to win this year's Nobel Prize himself, but rang Machado to congratulate her. Some members of Trump's administration had threatened the Nobel committee if he didn't win.
Edmundo Gonzalez, who was at the ceremony in Oslo, has since gone into exile in Spain, but Machado has remained in Venezuela, spending most of her time in hiding.
Her mother, sister and children have also travelled to Oslo to be reunited with her.
The decision to travel to Norway is fraught with risk.
Having successfully left the country, she faces a dangerous journey home again.
It certainly does for expectant mothers and their loved ones.
There have been marginal improvements (usually by one or two percentage points) in some areas of care, such as better communication around antenatal care or women being given enough time to ask questions about their pregnancies.
But what is clear is that far too many women felt they were not listened to or felt unsafe when left unattended at important times during labour.
The most disappointing thing about these findings is that this is exactly what has been exposed during one maternity scandal after another.
Mothers feeling unsafe, their worries brushed aside and having actions imposed on them without proper explanation.
Sky News has been inundated by similar messages from mothers failed by NHS maternity services.
We analysed 169 birth trauma stories and one of the most common themes represented was people feeling like they were being ignored, neglected or left alone by medical staff, or that their feelings and experiences were being dismissed.
Others said that staffing levels on maternity wards were not sufficient or that doctors, nurses and midwives were overstretched.

'We weren't listened to'
Others mentioned being forced into surgery or other medical procedures either against their will or that they think contributed to worse health outcomes for either them or their child.
Expectant mothers must not feel unsafe or feel that their unborn child will not receive the care they deserve.
Each successive report draws the same conclusion.
We know the problems. NHS maternity care needs urgent intervention.
