The US ambassador to the UN international organizations in Vienna, Laura Holgate, said on Tuesday that Iran should stop demanding the lifting of sanctions that go beyond the 2015 nuclear deal.

The ambassador claimed that it is Iran's demands for the lifting of these sanctions that are preventing a deal from being concluded in Vienna.

"Iran would need to drop demands for sanctions lifting that clearly go beyond the JCPOA and that are now preventing us from concluding a deal. Should Iran choose to join us, a mutual return to JCPOA implementation would be a significant achievement of international diplomacy and mark a new opportunity for creating the necessary assurances about Iran’s nuclear program going forward," Holgate said in a statement. 

According to the diplomat, the US is ready to lift the necessary sanctions that prevent a return to full implementation of the deal.

"We remain committed to working with our allies and partners to fully achieve that outcome if Iran is willing to do so," she added. 

The advisor to the Iranian delegation in the Vienna Talks, Dr. Mohammad Marandi, said on May 26 that the main issue for Iran in Vienna is that guarantees are made that the United States does not leave the deal again and that what concerns Iran is that guarantees are given for a sustainable deal, that investments can be made securely, and that the sanctions be removed.
