A senior negotiator rejected the demand by some parties to the Iran nuclear deal that the timeframe of a sanctions reinstatement mechanism be extended from 10 to 15 years.
The resolution recently adopted by the UN to endorse the agreement expressly states that the timeframe of the re-imposition plan is 10 years, Abbas Araqchi said.
"We do not regard the demand as valid" as it is a violation of the provisions of the agreement, he was quoted by IRNA as saying in a press conference on Wednesday.
Iran and the P5+1 (the United States, Britain, France, Germany, Russia and China) reached a deal on July 14 in Vienna to settle a long-running dispute over Tehran's nuclear program.
The accord -- officially named the Joined Comprehensive Plan of Action -- will lift sanctions against Iran in exchange for it agreeing temporary limitations on its nuclear program.
As set out in the UN resolution adopted on Monday, a "snapback" mechanism will be in effect over the next ten years to allow the sanctions against Iran to be reinstated in case it breaches the deal.
"We will closely monitor the other side's implementation of its obligations and should it commit any violation, we will take action to deal with it by the mechanisms defined in the pact," Araqchi said.
Pursuant to the deal, a joint commission consisting of the P5+1 and Iran will be established to monitor and address issues arising from the implementation of the agreement.
If the commission fails to resolve the issue, it will be referred to the Security Council.
Referring to a roadmap agreed with the International Atomic Energy Agency on the day the deal was reached to resolve the outstanding issues with the UN nuclear watchdog, the deputy foreign minister said access to military sites will be given based on the Additional Protocol to Iran's safeguards agreement with the agency.
Iran will voluntarily start the implementation of the protocol, Araqchi said, adding, "Since the implementation day (of the JCPOA), the required access will be provided to the IAEA based on the Additional Protocol."
"Access to non-nuclear centers will be allowed within the framework of international standards and the Additional Protocol."
