Update: Iran's FM says Lausanne agreement can help final nuclear deal

The solutions to Iran's nuclear program agreed in early April in Lausanne of Switzerland can help the settlement of the differences in a run for a final nuclear deal, Iran's Foreign Minister Mohammad-Javad Zarif told reporters upon arriving in Vienna on Tuesday.

"If there is an agreement to be reached, it should be inclusive of both western demands and ours. I think the deal should be based on Lausanne agreement which creates a possibility for a solution," Zarif was quoted as saying by official IRNA news agency. Iran is seeking a "fair and balanced" deal, he said in the fresh remarks.

The Iranian foreign minister was back to Tehran on Sunday to consult with Iran's top officials following several rounds of meetings with U.S. Secretary of State John Kerry and his European counterparts in Vienna.

Zarif, along with Iran's atomic chief Ali-Akbar Salehi, and president's special aide Hossein Fereidoun arrived in Vienna on Tuesday to hammer out a long-awaited deal at the last hours of the self-imposed deadline.

Earlier on Saturday, Iran's senior nuclear negotiator Abbas Araqchi had said that parts of the solutions on Iran's nuclear issue reached in Lausanne early April are not feasible.

"We reached some good solutions in Lausanne and they are now used (for preparing the draft for a deal), ... however, some solutions of Lausanne are not approachable," Araqchi said.

Iran and the United States have somewhat different interpretations on the details of the sanctions relief policy outlined in Joint Comprehensive Plan of Action (JCPOA) of April 2.

Zarif reiterated on Tuesday that "reaching a long-term nuclear deal would be unlikely without recognizing Iranians' nuclear rights." No deal can be sealed unless agreement on all the issues is reached, he stressed.

Iran and five UN Security Council permanent members plus Germany have been negotiating over the past 14 months to reach a long-term deal over Tehran's disputed atomic plan. Endit
