The U.S. and Ukraine have agreed on the terms of a draft minerals deal central to Kyiv's push to win Washington's support as President Donald Trump seeks to rapidly end the war with Russia, Reuters reported on Tuesday, citing two sources with knowledge of the matter.

According to the report, a source familiar with the contents of the draft agreement said that it does not specify any U.S. security guarantees or continued flow of weapons but says that the United States wants Ukraine to be "free, sovereign and secure."

Future weapons shipments are still being discussed between Washington and Kyiv, the report added, citing one of the sources familiar with the deal.

Trump told reporters that Ukrainian President Volodymyr Zelenskyy wants to come to Washington on Friday to sign a "very big deal." This came after the two leaders exchanged hostile words last week.

The U.S. president, who has cast the deal as a repayment for billions of dollars in aid to Kyiv, also said some form of peacekeeping troops are needed in Ukraine if an agreement to end the conflict is struck. Moscow, which launched a special military operation in Ukraine three years ago, has refused to accept any deployment of NATO forces.

Some European countries have said they would be willing to send peacekeeping forces to Ukraine. Trump said on Monday that Moscow would accept such peacekeepers, but the Kremlin denied that on Tuesday.

Trump's rush to impose an end to Russia-Ukraine conflict and his lurch toward Moscow has stoked fears of far-reaching U.S. concessions to Russian President Vladimir Putin that could undermine security in Ukraine and Europe and alter the geopolitical landscape.

Officials on both sides have agreed to the draft and advised it should be signed, the sources said. The deal could open up Ukraine's vast mineral wealth to the U.S.

"What we're doing is now we're saying, look, we want to be secured," Trump said. "The American taxpayer now is going to get their money back, plus."

Zelenskyy refused to sign an earlier draft of a minerals agreement as Washington sought rights to $500 billion in Ukraine's natural wealth. Kyiv protested it had received far less than that in U.S. aid and the deal lacked the security guarantees Ukraine needs.

Under the terms of a draft minerals agreement, according to sources familiar with its contents, the United States and Ukraine would establish a Reconstruction Investment Fund to collect and reinvest revenues from Ukrainian sources, including minerals, hydrocarbons and other extractable materials.

Ukraine would contribute to the fund 50 percent of the revenue minus operating expenses and continue until the contributions reach the sum of $500 billion. The United States would provide a long-term financial commitment to the development of a "stable and economically prosperous Ukraine."

Asked what Ukraine would get in return for the minerals deal, Trump cited what he said was $350 billion already provided by the U.S. "and lots of military equipment and the right to fight on."

Scott Anderson, a fellow in governance studies at the Brookings Institution, said that while the minerals deal would look like "a kind of piracy" to much of the world, it is necessary to get buy-in from Trump and Republican lawmakers.

"They say this gives him (Trump) real skin in the game. I think there is real logic to that," Anderson said.

"I hear that he's coming on Friday," Trump told reporters. "Certainly it's okay with me if he'd like to. And he would like to sign it together with me."

Ukraine has deposits of 22 of the 34 minerals identified by the European Union as critical, according to Ukrainian data. They include industrial and construction materials, ferroalloy, precious and non-ferrous metals, and some rare earth elements.

Ukraine's reserves of graphite, a key component in electric vehicle batteries and nuclear reactors, represent 20 percent of global resources.
