TEHRAN - Iran on Monday urged the United States to move away from the anti-Iran policies imposed by former US President Donald Trump to help advance the current nuclear talks underway in the Austrian capital of Vienna.

"If the United States decides to distance from Trump's failed legacy and to live up to its commitments, the consultations will advance easily," Iran's Foreign Ministry spokesman Saeed Khatibzadeh told a weekly press conference.

Iran's Foreign Ministry spokesman Saeed Khatibzadeh also called on the US government to lift sanctions and adhere to its obligations

Khatibzadeh also called on the US government to lift sanctions and adhere to its obligations.

Iran's decision to scale back from some of its nuclear commitments "will only stop when the United States lifts sanctions, and we can verify them," he added.

Meanwhile, the European Union's top diplomat, Josep Borrell, said on Monday he saw a willingness to save the 2015 nuclear deal between Iran and global powers, citing progress in talks in Vienna to bring the US back to the accord.

The optimism follows comments by China's envoy to the negotiations, Wang Qun, on Saturday that negotiations were starting to pick up pace.

"I think that there is real good will among both parties (Iran and the United States) to reach an agreement, and that's good news," he said, citing progress but not giving details.

"I think that both parties are really interested in reaching an agreement, and they have been moving from general to more focused issues, which are clearly, on one side sanction-lifting, and on the other side, nuclear implementation issues."
