Investing.com -- President Donald Trump announced on Tuesday that Iran had delivered what he described as a significant energy-related concession to the United States, though he declined to provide specific details about the nature of the gift.

Speaking to reporters in the Oval Office, Trump said Iran offered the concession as a show of good faith during negotiations aimed at ending a 25-day conflict that has disrupted global markets.

"They gave us a present and the present arrived today, and it was a very big present, worth a tremendous amount of money," Trump said. "I’m not going to tell you what that present is. It was a very significant prize and they gave it to us. They said they were going to give it to us so that meant one thing to me, we’re dealing with the right people."

Trump indicated the concession was related to the Strait of Hormuz, the oil transit waterway that the United States has struggled to keep open during the conflict.

"It wasn’t nuclear, it was oil-and gas-related, and it was a very nice thing they did," Trump said.

The president said the United States was currently in negotiations with Iran to reach a deal to end hostilities, adding that Iranian officials wanted to reach an agreement. Trump said U.S. envoys Steve Witkoff and Jared Kushner, along with Vice President JD Vance and Secretary of State Marco Rubio, were involved in the negotiations. He did not confirm whether Witkoff and Kushner planned talks this week.

Pakistan has said it is willing to host talks between the United States and Iran.

Trump has deployed additional troops to the Middle East during the ongoing conflict.
