Announcing the meeting, Zelenskiy said "a lot can be decided before the New Year," as the United States drives efforts to end Russia's full-scale war in Ukraine.
"As for the sensitive issues: we will discuss both Donbas and the Zaporizhzhia nuclear power plant. We will certainly discuss other issues as well," he told reporters in a WhatsApp chat.
A security guarantee agreement between Ukraine and the US is "almost ready" and the 20-point plan draft was 90 per cent complete, Zelenskiy told reporters in a WhatsApp chat.
"He doesn't have anything until I approve it," Trump told Politico in an interview published on Friday. "So we'll see what he's got."
Zelenskiy told Axios the US offered a 15-year deal on security guarantees that could be renewed, and Kyiv wanted a longer term.
Wary of failed guarantees from allies in the past, Ukraine is seeking robust and legally binding deals to prevent further Russian aggression.
Zelenskiy said his meeting with Trump aimed to "refine things" in the drafts and to discuss potential deals on Ukraine's economy.
He added that he was not ready to say if any deal would be signed during his visit, but Ukraine was open to it.
Trump said he believed the meeting was going to go well, while he expected to speak to Russian President Vladimir Putin "soon, as much as I want."
Territorial issues remain a hurdle to negotiations moving forward.
"As for the sensitive issues: We will discuss both Donbas and the Zaporizhzhia nuclear power plant. We will certainly discuss other issues as well," Zelenskiy said as he unveiled the agenda for the meeting.
Moscow demands that Ukraine withdraw from the parts of the eastern Donetsk region that Russian troops have failed to occupy during almost four years of war, as it seeks full control of the Donbas, comprising the Donetsk and Luhansk regions.
Kyiv wants the fighting to be halted at the current lines.
The US, seeking a compromise, proposed a free economic zone if Ukraine leaves parts of the Donetsk region. The proposal gave no details on how the zone would function.
Zelenskiy was cited by Axios as saying that if he is not able to push the US to back Ukraine's "strong" position on the land issue, he is willing to put the 20-point plan to a referendum - as long as Russia agrees to a 60-day ceasefire to allow Ukraine to prepare for and hold the vote.
Trump, who has at times expressed frustration with the slow pace of progress in the negotiations, previously suggested that he would meet with Zelenskiy if he felt that a major diplomatic advance was possible.
European leaders might join the talks online, according to Zelenskiy.
On Friday, he discussed preparations for the Sunday meeting and progress in talks with some European leaders, including NATO chief Mark Rutte and Finnish President Alexander Stubb, who is seen as close to Trump.
Russian Deputy Foreign Minister Sergei Ryabkov said Kyiv's version of the 20-point plan was radically different from what Russia has been discussing with the US, according to Interfax-Russia.
He added, however, that: "I think that 25 December 2025 will remain in our memory as a turning point, when we came closer, indeed closer, to a solution."
Putin's foreign policy aide, Yuri Ushakov, spoke with members of the Trump administration after Moscow received US proposals about a possible peace deal, the Kremlin said. It did not disclose how Moscow viewed the documents.
Russia's Kommersant newspaper reported that Putin told some of Russia's top businessmen that he might be open to swapping some territory controlled by Russian forces elsewhere in Ukraine, but that in exchange he wanted the whole of the Donbas.
