As reported by this American media, Trump first said that the talks were moving "a little slowly," but then, half an hour later, he called the journalist again and emphasized that direct negotiations would soon resume.

"You should really stay there, because something could happen in the next two days, and we are more inclined to go to Islamabad," Trump said.

He pointed out that staying in Islamabad, despite talks of other locations, is the result of the positive relationship between U.S. representatives and Field Marshal General Asim Munir, with whom Trump developed a rapport during negotiations on ending the war between Pakistan and India last year.

"He is fantastic, and thatโ€™s why itโ€™s more likely weโ€™ll return there. Why would we go to a country that has nothing to do with it?" added the American president.

Trump also hinted that he was not satisfied with reports that the U.S. had asked Iran to suspend its uranium enrichment program for at least two decades during the unsuccessful talks held last weekend.

"Iโ€™m saying they canโ€™t have nuclear weapons, so I donโ€™t like that 20 years," added Donald Trump in an interview with the New York Post.

Recall that the first round of talks in Islamabad ended without an agreement after as many as 21 hours of discussions between U.S. and Iranian representatives.
