Behrouz Kamalvandi, spokesman for the Atomic Energy Organization of Iran.

The spokesperson for the Atomic Energy Organization of Iran, Behrouz Kamalvandi, described IAEA's demands from Iran as excessive, noting that these demands cannot be implemented due to West-led sanctions.

Referring to an Iranian law that goes by the name "Strategic Action Plan to Lift Sanctions and Protect Iranian Nation's Interest," the IAEA is supposed to maintain minimum supervision of Iranian nuclear sites, according to Kamalvandi.

If the West lifts the sanctions and goes back to sticking to its commitments, Iran will reciprocate its commitments under the JCPOA, he said.

Referring to Iran's June measure to disconnect 27 surveillance cameras at different nuclear sites, Kamalvandi noted that if the other parties return to their commitments, these devices could possibly start working again.

Just weeks after the deal seemed to have died, the EU put forward on August 8 what it called a final text to restore the agreement, in which Iran would see sanctions relief and be able to sell its oil again in return for severe limits on its nuclear program.

Iran came back two weeks ago with a series of proposed changes, to which the US formally responded on Wednesday, a day after Tehran accused the US of spreading false information about its nuclear activities.

The 2015 agreement between Iran and six world powers -- the UK, China, France, Germany, Russia, and the US -- gave the Islamic republic sanctions relief in exchange for curbs on its nuclear program.

In June, Iran abandoned all commitments beyond the Safeguards Agreement in response to the International Atomic Energy Agency's Board of Governors' adoption of an anti-Iran resolution.
