The IAEA distributed a new report on Iran's nuclear development to board members on Friday.
Iran signed the nuclear deal in 2015 with the United States, Germany, France, the United Kingdom, China and Russian Federation. Known as the Joint Comprehensive Plan of Action, or JCPOA.
The other report said that Iran's stock of low-enriched uranium (LEU) rose by 534kg in the most recent quarter, roughly the same amount as in the previous three months, to 2,105.4kg.
US President Donald Trump in 2018 pulled out of the global agreement signed with the country to prevent it from acquiring nuclear weapons, which he said was ineffective, and immediately re-established and tightened US sanctions against the Islamic Republic.
At the same time, he said, "not a single friendly country told us that in this time of coronavirus and hardship and for the sake of humanity "we will stand up to America" and do business with Iran despite threats of United States retaliation.More news: More people in the Quinte region are getting back to work
An inspection at the second site will take place "later in September 2020 on a date already agreed with Iran", the report said.
Iran's move came in retaliation against US sanctions reinstated by President Trump.
Since then, Iran has slowly violated the restrictions to try and pressure the remaining nations to increase the incentives to offset new, economy-crippling U.S. sanctions.
The report says that after a visit to Tehran by IAEA Director General Rafael Grossi in late August, Iran agreed to provide inspectors access to two sites where it was suspected that nuclear material was stored.
Those countries maintain that even though Iran has been violating numerous pact's restrictions, it is important to keep the deal alive because the country has continued providing the IAEA with critical access to inspect its nuclear facilities.More news: Arrests at Australia anti-lockdown protests
The IAEA said Iran had granted its inspectors access to one of the two sites.
The ultimate goal of the JCPOA is to prevent Iran from developing a nuclear bomb, which Iran insists it does not want to do.
Tehran is enriching up to a fissile purity of 4.5 percent, which while above the deal's 3.67 percent limit is still far short of the 20 percent higher-enriched level it achieved before the deal.
Iran, with over 380,000 registered cases and over 22,000 deaths from the coronavirus, is one of the countries worst-hit by the pandemic in the Middle East.More news: AJ Styles Confirms He Tested Positive For COVID-19
