Since the beginning of the war, Trump has repeatedly demanded that Iran not be allowed to enrich uranium, citing the risk that the country could develop nuclear weapons.
The disagreement between the United States and Iran over the nuclear issue was the stumbling block that caused the historic negotiations in the Pakistani capital Islamabad to collapse.
Iran may consider agreeing to a five-year ban on uranium enrichment. The United States rejected the offer and is demanding a halt of at least 20 years, according to two Iranian sources and one American source, The New York Times reports.
Despite the U.S. blockade of shipping from Iran and Iran's threat of retaliation for the blockade, a second round of talks between the U.S. and Iran is reportedly on the cards, according to sources in Pakistan's mediation delegation. U.S. President Donald Trump is reported to have said that Iran "wants to work on a deal."
The ambition is for details of a second meeting between the U.S. and Iranian delegations to be decided before the temporary ceasefire expires next week, CNN reports.
President Trump told a reporter from The New York Post on the ground in Pakistan on Tuesday that the reporter should stay two more days in Islamabad, where the previously collapsed talks were held.
Trump also said in Tuesday's phone conversation that Pakistan is a good place for talks as the country's army chief, Asim Munir, is "doing a fantastic job."
