The US and Ukraine have been trying to hammer out the natural resources agreement since US President Donald Trump returned to the White House in January.

The deal comes after weeks of intense negotiations that at times turned bitter and temporarily derailed Washington’s aid to Ukraine.

The US Treasury Department on Wednesday announced that both countries signed the agreement. “As the President has said, the United States is committed to helping facilitate the end of this cruel and senseless war,” Treasury Secretary Scott Bessent said in a statement.

“This agreement signals clearly to Russia that the Trump Administration is committed to a peace process centered on a free, sovereign, and prosperous Ukraine over the long term,” Bessent said, adding, “And to be clear, no state or person who financed or supplied the Russian war machine will be allowed to benefit from the reconstruction of Ukraine.”

Ukraine’s Economy Minister Yulia Svyrydenko was in Washington to sign on behalf of the Ukrainian government.

Among the terms of the agreement are “full ownership and control” staying with Ukraine, she posted to X on Wednesday.

“All resources on our territory and in territorial waters belong to Ukraine,” she said, adding: “It is the Ukrainian state that determines what and where to extract. Subsoil remains under Ukrainian ownership — this is clearly established in the Agreement.”

The signing comes hours after a last-minute disagreement over which documents to sign Wednesday threatened to derail the deal.

Ukraine’s President Volodymyr Zelensky was expected to strike the deal during his trip to Washington in February – but the agreement was left unsigned when that visit was cut short following the contentious Oval Office meeting.

Among the key sticking point of the negotiations was the question of security guarantees – and whether the US would provide them as part of the deal. Trump initially refused that, saying he wants Ukraine to sign the agreement first and talk about guarantees later.

At that time, Zelensky described the draft agreement as asking him to “sell” his country. Ukrainian officials have since indicated they believed that US investment and the presence of American companies in Ukraine will make the US more interested in Ukraine’s security.

Shortly after the doomed White House visit, Trump ordered US aid to Ukraine to be suspended. While the assistance has since been restored, the episode became a major wakeup call for Ukraine’s European allies, who have pledged to step up their help to the country.

Trump has largely billed the agreement as Ukraine “paying back” for the aid the US has provided to Ukraine since Russia launched its unprovoked full-scale invasion of the country in February 2022.

Speaking to Fox News Wednesday, Bessent said the deal is “a signal to the American people, that we have a chance to participate, get some of the funding and the weapons, compensation for those.”

The details of the agreement have not been made public. However, Ukraine’s Prime Minister Denys Shmyhal said on Sunday that the deal “will not include assistance provided before its signing.”

Speaking on Wednesday, Shmyhal described the deal as “a strategic agreement on the establishment of an investment partnership fund.”

“It is truly an equal and beneficial international agreement on joint investments in the development and recovery of Ukraine between the US and Ukrainian governments,” he added.

Under the deal, the US and Ukraine will create a joint investment fund in Ukraine with an equal contributions from both and equal distribution of management shares between them, Shmyhal said.

“The American side may also count new, I emphasize new, military aid to Ukraine as a contribution to this fund,” Shmyhal said.

Kyiv’s allies have long eyed the country’s mineral riches. Ukraine has deposits of 22 of the 50 materials classed as critical by the US Geological Survey.

These include rare earth minerals and other materials that are critical to the production of electronics, clean energy technologies and some weapon systems.

The global production of rare earth minerals and other strategically important materials has long been dominated by China, leaving Western countries desperate for other alternative sources – including Ukraine.

A memorandum of understanding prepared under the Biden administration last year said the US would promote investment opportunities in Ukraine’s mining projects to American companies in exchange for Kyiv creating economic incentives and implementing good business and environmental practices.

Ukraine already has a similar agreement with the European Union, signed in 2021.

The Times was given a rare insight into conversations between Europe’s defense ministers and military chiefs as they thrashed out plans for a “coalition of the willing” force.

Admiral Sir Tony Radakin, the British chief of the defense staff, is said to have asked his counterparts on the Continent if they could put together a 64,000-strong force to send to the country in the event of a peace deal.

He said Britain would be willing to send up to 10,000 personnel in a meeting earlier this month.

However, at the next meetings, defense ministers from all over Europe stated that they had no chance of recruiting 64,000 troops. Close allies expressed their doubts to British Defense Minister John Healey. They indicated that a force of this size would require a total of 256,000 troops over two years, taking into account rotation.

The European military declared that even 25,000 people “would become a target for joint efforts,” stated a source privy to the discussions in Brussels. According to him, Estonia and Finland were concerned that any deployment would “weaken” their own border defenses, and Poland, Spain and Italy made it clear that they would not give their soldiers.

It is now assumed that Britain and France will send instructors to Western Ukraine instead of multinational ground forces.

Russia has repeatedly stated that the appearance of NATO troops in Ukraine is unacceptable.
