"Reaching an agreement with the Group 5+1 (the five permanent UN Security Council members plus Germany) will be imminent if it is based on the NPT and the members' rights," Foreign Ministry Spokesman Ramin Mehman-Parast said in the Southwestern city of Ahwaz on Monday.
He said that Iran expects the world power not to delay the talks and continue negotiations based on the NPT, and added, "The western members of the G5+1 may claim that they have some ambiguities and concerns but if our rights are fully recognized in the two sides' agreement, we can strike a deal to obviate the ambiguities and concerns."
Mehman-Parast underlined Iran's commitment to its undertakings based on the NPT, and said, "We defend the Iranian nation's rights to use the nuclear know-how in line with peaceful goals and path of the country's development and progress."
On April 6, Iran and the six world powers wrapped up two days of intensive negotiations in Almaty.
The Iranian team was led by Saeed Jalili, who is also the Secretary of Iran's Supreme National Security Council (SNSC), and the G5+1's representatives were presided by Ashton.
Also in April, Mehman-Parast described the latest round of talks with the world powers in Kazakhstan as "positive", and said Tehran is waiting for the opposite side's response to its proposals.
"The two sides' comments described as positive the start of straightforward and serious expression of views, and to take a correct step, our officials expressed their views and the G5+1 should now respond," Mehman-Parast said at a weekly press conference in Tehran.
"We are (now) waiting for Mrs. Ashton's response and her consultations with the G5+1," he added.
