The United States and Iran are set to hold a new round of nuclear negotiations on Sunday in Oman, officials confirmed, just before President Donald Trump’s scheduled visit to the region.

Trump, who will also travel to three Gulf Arab monarchies during his trip, has expressed optimism about reaching a potential deal with Tehran to prevent an Israeli military strike on Iran’s nuclear facilities—a move that could escalate into a broader conflict.

Iranian Foreign Minister Abbas Araghchi stated that Oman, which has been mediating the talks, proposed Sunday as the meeting date, and both Washington and Tehran agreed.

"Negotiations are progressing, and naturally, as we advance, more consultations are needed, requiring additional time for delegations to examine the issues," Araghchi said in a video released by Iranian media.

He added, "What’s important is that we are moving forward, gradually delving into the details."

According to a source familiar with the arrangements, Steve Witkoff, a longtime friend of Trump who has acted as his international negotiator, will participate in the discussions. This marks the fourth round of talks since Trump returned to the White House.

The meeting comes amid heightened tensions over Iran’s nuclear program and regional stability, with global observers closely watching whether the two sides can make progress toward averting further escalation.
