Ukrainian President Volodymyr Zelensky said that Kyiv formally received a new minerals deal proposal from Washington giving US access to Ukrainian natural resources in exchange for further military support.
"I would like to note that officially, and this is important, the Ukrainian side, namely the cabinet of ministers of Ukraine and my office, today by a note, we officially received... the US proposals today," Mr Zelensky said at a press conference in Kyiv.
A planned deal on extracting strategically important minerals in Ukraine with the US had been set to be signed in Washington last month, until a spectacular televised clash between Mr Trump and Mr Zelensky.
Mr Trump said in a White House address last week that the US would "very shortly" sign a pact with Ukraine.
US Treasury Secretary Scott Bessent told Fox News this week that the US had handed over a finalised partnership document that it hoped could be signed as soon as next week.
Ukrainian Deputy Prime Minister Yulia Svyrydenko wrote on Facebook on Friday that Ukraine "is working to ensure that the agreement reflects all our interests".
Mr Zelensky said that his government needed to review the text of the draft agreement it received with lawyers.
Ukraine once hoped to get security guarantees in exchange for access to mineral resources, but initial drafts included little protection, and the US has rejected sending any peacekeeping forces to Ukraine.
Putin calls to remove Zelensky, 'finish off' Ukrainian troops
Meanwhile, Russian President Vladimir Putin called for a "transitional administration" to be put in place in Ukraine and vowed his army would "finish off" Ukrainian troops.
Mr Putin also issued a public call for Ukraine's generals to topple Mr Zelensky, whom Mr Putin has repeatedly denigrated, without providing any evidence, as a neo-Nazi and drug addict.
Asked about Mr Putin's remarks later on Friday, Kremlin spokesman Dmitry Peskov said it was motivated by what Russia sees as the Ukrainian leadership's "total lack of control" over the army, which he accused of trying to attack Russian energy sites "on a daily basis".
On the battlefield, Russia's defence ministry claimed fresh advances, saying its troops had seized a village in Ukraine's northeastern Kharkiv region and retaken a border settlement in its own Kursk region.
The latest territorial gains came after Mr Putin urged his troops to press their advantage in manpower and weapons.
"I was saying not so long ago: 'We will get them.' There are reasons to believe that we will finish them off, too", Mr Putin said.
In a sign of the high cost of the war, Ukraine said it had received 909 bodies of Ukrainian soldiers killed in battle - the largest yet.
Ukraine will not recognise old US military aid as loans - Zelensky
Mr Zelensky has said that Ukraine would not recognise previously approved US military aid as loans that need repaying, as he confirmed that Kyiv had received a new draft minerals deal from the United States.
Speaking at a news conference in Ukraine, Mr Zelensky also said that Ukraine would be ready to engage in talks with any representative from the Russian side - apart from Mr Putin.
Mr Zelensky added that Ukraine would not accept a deal that threatens its integration with the European Union.
Meanwhile, the EU's commissioner for agriculture said the bloc expects to reduce farm imports from Ukraine as it reviews emergency measures to support Kyiv that opened up its market for Ukrainian products.
Christophe Hansen said Brussels was seeking to "find a new agreement" before the measures, which have upset European farmers, expire in June.
"Discussions will have to be swift. The European Union is ready to negotiate, and it should happen in the coming weeks," he said in an interview.
"Import quotas won't remain the same as in this temporary liberalisation. So, indeed, there will be fewer imports."
After Russia's 2022 invasion, the EU eliminated tariffs on Ukrainian products in a show of support as the war severely limited Ukraine's usual sea export routes.
But European farmers protested they were being undercut by an influx of cheaper goods produced by their less-regulated Ukrainian peers.
In response last year, the EU imposed some limits on products including sugar, poultry, eggs and corn.
"We've seen that this has caused problems, especially in certain member states," Mr Hansen said of the temporary measures, adding it was "clear" that EU countries do not favour an extension.
If duty-free access is not renewed in June, trade between the EU and Ukraine will return to being regulated by a pre-existing deal.
"The best thing would be for us to have a longer-term agreement with Ukraine, including an alignment of production standards," Mr Hansen said.
Russian drone attack kills four, injures 15 in Ukraine's Dnipro
A mass Russian drone attack killed four people, injured 15 and sparked a large fire in a hotel and restaurant complex and other buildings late in the southeastern Ukrainian city of Dnipro, the regional governor said.
Serhiy Lysak, governor of the surrounding Dnipropetrovsk region, said the casualty toll was likely to rise, with three of the injured in serious condition.
Firefighters were bringing the blaze under control.
"It is also now known that the enemy directed more than 20 drones toward the city," Mr Lysak wrote on the Telegram messaging app.
"Most of them were downed."
Pictures and videos posted online showed flames and large plumes of smoke wafting skyward in the city.
Others showed the shattered interior of a building, the badly-damaged upper floors of a high-rise apartment block and streets strewn with smashed glass and building materials.
