Russia blamed on Friday the United States of seeking agreements on issues unrelated to the nuclear file in its negotiations with Tehran over its nuclear deal.
Russia's Governor to the International Atomic Energy Agency (IAEA), Mikhail Ulyanov expected diplomatic efforts to conclude in the coming days.
Conflicting reports have emerged that Washington would soon respond to a package of suggestions proposed by Iran in response to the European Union’s "final" proposal over the nuclear deal.
Ulyanov said the parties to the nuclear talks could reach a unanimous agreement about reviving the deal on September 1.
He revealed that "several issues" have been reached to revive the 2015 pact, which sought to limit Iran’s nuclear activities in exchange for sanctions relief.
The EU is trying to bridge divides, but "we have the impression that Washington wants to resolve issues that are unrelated to the nuclear deal," he added.
On Monday night, Tehran announced that it had submitted its "written response to the text proposed by the European Union," saying that an agreement would be reached if the American answer was realistic and flexible.
State Department spokesperson Ned Price said on Tuesday the administration is reviewing Tehran’s response.
The EU also said it was studying Iran's response.
After 16 months of fitful, indirect US-Iranian talks, with the EU shuttling between the parties, a senior EU official said on Aug. 8 the bloc had laid down a "final" offer and expected a response within a "very, very few weeks".
Washington has said it is ready to quickly seal a deal to restore the accord on the basis of the EU proposals.
