“We reached agreement on the resolution of the safeguards implementation issues raised by the Agency. The Agency subsequently conducted a complementary access, under the Additional Protocol, at one of the two locations specified by us,” IAEA’s Director General Rafael Grossi said on Monday, Press TV reported.

Addressing the agency’s 35-member Board of Governors, he added, “Our inspectors took environmental samples which will be analyzed. A complementary access at the second specified location will take place later this month.”

He noted that during his visit to Tehran, he held talks with Iranian President Hassan Rouhani and other senior officials “aimed at making concrete progress in addressing the Agency’s outstanding questions, and in particular at resolving the issue of access to two locations in Iran.”

At the end of Grossi’s two-day trip to Tehran on August 26, Iran and the UN agency issued a joint statement on their agreements and the results of high-level talks between the two sides.

“After intensive bilateral consultations, Iran and the IAEA reached an agreement on the resolution of the safeguards implementation issues specified by the IAEA, in good faith. In this regard, Iran is voluntarily providing the IAEA with access to the two locations specified by the IAEA and facilitating the IAEA verification activities to resolve these issues,” read part of the statement.

In his Monday speech, the UN nuclear agency chief also welcomed the Iran-IAEA agreement and expressed hope that it would “reinforce cooperation and enhance mutual trust.”

Grossi added that the agency would continue to verify the non-diversion of nuclear material declared by Iran under its Safeguards Agreement, saying, “Evaluations regarding the absence of undeclared nuclear material and activities for Iran continue.”

Meanwhile, the IAEA chief told reporters after opening the Board of Governors’ meeting that analyzing environmental samples collected at the first site would take “not less than a couple of months, two or three months maybe.”

Iran’s permanent representative to the Vienna-based international organizations Kazem Gharibabadi said on September 4 the latest IAEA report envisaged “positive and constructive” prospects in bilateral cooperation.

“In terms of content, the report has explicitly portrayed a clear image of the current status of [bilateral] cooperation and envisaged positive and constructive prospects in relations between Iran and the agency,” he told reporters.

The Iranian official said it was expected that an overwhelming majority of the IAEA member states and the Board of Governors would approve of the constructive nature of the relationship between Tehran and the agency.

Under the 2015 accord, the IAEA monitors Iran’s nuclear activities and regularly updates its members through providing reports.

The visit by the IAEA head to Tehran took place over two months after the Board of Governors on June 19 passed a resolution, put forward by Britain, France and Germany – the three European signatories to the landmark 2015 nuclear agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA), to push for inspections of two sites that the trio claims may have been used for undeclared nuclear activities in the early 2000s.

It was the Israeli regime’s spy service that first came up with the allegations of such activity at the two sites. Iran has, however, strictly rejected the allegations.

Gharibabadi said the IAEA’s quarterly report, released earlier on Friday, dealt with the developments and progress of relations and cooperation between Iran and the UN nuclear watchdog over the past three months, IRNA reported.

The international body confirmed that Iran has let the IAEA inspect one of the two sites it agreed to grant access to in a joint statement issued last month at the end of a visit to Tehran by the IAEA’s chief.

“According to the report, the agency has been gained access to one of the two intended sites and the access to the second site has been scheduled for this month,” Gharibabadi said while speaking to reporters Friday evening,.

He described the report “significant,” adding that it can be scrutinized from two angles.

In terms of form, he said, the report “indicates the constructive interaction of the two sides during the period to reach a common understanding and find solutions” to issues.

“While in terms of content, this report clearly portrays a clear and positive image of the current status of cooperation and a positive and constructive outlook in relations between Iran and the IAEA, which is expected to be welcomed by the overwhelming majority of IAEA member states and the Board of Governors,” the envoy added.

Gharibabadi further noted that the report pointed to a trip to Tehran by the IAEA’s chief Rafael Grossi on August 24 and 25 and his talks with senior Iranian officials, which led to the issuance of a joint statement aimed at strengthening cooperation and building more confidence.

Iran has shown goodwill in its interaction with the IAEA’s new director general, and expects the joint statement and director general’s report be supported by members of the Board of Governors and other IAEA members and be considered a major step toward normalizing two or three Iran-related safeguards issues with independent, impartial and professional implementation of agreements and commitments, Gharibabadi said.
