President Donald Trump on Monday indicated that he wants to reach an agreement with Ukraine to gain access to the country’s rare earth materials as a condition for continuing U.S. support for its war against Russia.

Axar.az reports that, citing Associated Press, speaking to reporters in the Oval Office, Trump complained that the U.S. had sent more in military and economic assistance to Ukraine than its European partners, adding, “We’re looking to do a deal with Ukraine where they’re going to secure what we’re giving them with their rare earth and other things.”

Trump suggested that he’s received word from the Ukrainian government that they’d be willing to make a deal to give the U.S. access to the elements critical to the modern high-tech economy.

“I want to have security of rare earth,” Trump added. “We’re putting in hundreds of billions of dollars. They have great rare earth. And I want security of the rare earth, and they’re willing to do it.”
