TEHRAN, May 25 (Xinhua) -- The latest report by the UN nuclear watchdog is another indication of Iran's adherence to 2015 nuclear deal, Iran's Ambassador to the International Atomic Energy Agency (IAEA) Reza Najafi said, according to Tasnim news agency's Friday report.

The IAEA's new report, the 11th one since the implementation day of nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA), once again confirms that Iran's nuclear measures and activities are fully in compliance with the JCPOA, Najafi was quoted as saying.

The recent text of the IAEA report is similar to the previous reports and the only changes relate to technical figures, like a planned increase in the stockpile of heavy water and the enriched uranium, he said.

A confidential report of IAEA on Thursday showed Tehran is still complying with the historic nuclear deal after the United States' withdrawal from the deal.

The report said the IAEA is monitoring Iran's nuclear plan under the JCPOA. There is no sign in the report that Iran is violating the deal, which freezes its atomic plan.

China, Russia, Britain, France, Germany and Iran are to meet on Friday in Vienna to discuss the Iranian nuclear deal for the first time after U.S. pullout from the accord.

In July 2015, six world powers and Iran signed the JCPOA in the Austrian capital, a landmark deal which eased sanctions on Iran in exchange for Tehran limiting its nuclear program. The parties began to implement the accord in January 2016.
