Deputy Foreign Minister in Legal and International Affairs Abbas Araqchi said in talks with Group 5+1, we have reached agreement on 70 percent of issues, IRNA reported.
Araqchi made the remarks in a live IRIB TV Channel 2 interview on Monday evening.
On the remaining 30 percent, he said, we have not agreed yet, but we have had good progress.
He expressed hope that in the next round of talks on September 18 in New York, the two sides can reach good agreements.
Araqchi also said Foreign Minister Zarif will meet his Chinese counterpart on the sidelines of the Shanghai Cooperation Organization meeting.
It is obvious that an important part of talks should be with the Americans, because most of the sanctions have been imposed by the USA and removing the sanctions depends on talks with them.
Deputy Foreign Minister expressed hope that existing problems could be settled and negotiation end until November 24.
Araqchi reminded that enrichment right is an important issue which we emphasized on because it is completely industrial and would be used for the country's future needs.
He explained that Arak is another important issue; of course there are concerns about a heavy water reactor,too.
Ways to remove sanctions are a key issue and upon Geneva agreement, one of the components of final agreement is removing sanctions. The sanctions have been imposed by different authorities such as the USA, Europe and the UN Security Council and removing them is complicated.
Concerning new US imposed sanctions, Araqchi said that upon Geneva agreement, no new sanctions should be imposed, but the Americans believe that some of the sanctions on companies are not new.
Adding names of a number of persons, who violated sanctions, in our view, is considered as imposing new sanctions.
Deputy Foreign Minister in Legal and International Affairs continued we do not allow those who do not want the talks reach a conclusion and create disruption on its way, to cut negotiation.
Our cooperation directions with the International Atomic Energy Agency and Group 5+1 are parallel, but they go ahead independently.
We have been committed on safeguards and Geneva agreements and IAEA report confirmed it and only the issue of answering a number of claims from the past has remained.
Araqchi said that cooperation between Iran and the agency will continue, adding that 'PMD' or passible military dimension of Iran's nuclear activities belongs to the past and we do not believe in PMD.
He reminded that in the field of oil drilling we use detonators which are very sensitive and the issue had been declared to the agency.
This ability is serving country's industry and economy and the agency had also declared that using the detonators industrially is logical.
Araqchi underlined that Iran is ready for bilateral talks with member states of the Group 5+1 or by foreign ministers of the group in New York in mid-September.
He added that Iran remains at the negotiation table until the last minute and follows the directions seriously.
Access to understanding about nuclear issue is a hard work, but not impossible, serious differences exist, but solutions existed, too.
In Geneva agreement, it is referred to confidence building toward Iran's nuclear program; if such an important issue is considered, final agreement would be possible.
Araqchi said that one-year opportunity for talks will end on November 24 and explained that continuation of current situation would be very difficult after the date and after the due time, situations in the USA and Europe will be different.
He said that created opportunity by Geneva agreement, in case of no access to agreement will be lost, but diplomacy will always continue.
