DUBAI, Nov 11 (Reuters) - The United Nations atomic energy watchdog and Iran on Monday signed a joint statement on future cooperation to resolve remaining nuclear issues.
The agreement is a step towards resolving concerns of the International Atomic Energy Agency (IAEA) about Iran's nuclear activities and opens the way for its inspectors to visit two more nuclear sites, the Arak heavy water site and the Gachin uranium mine.
"The joint statement that was signed today represents a road map that specifies bilateral steps in relation to resolving outstanding issues," the head of Iran's atomic energy organisation, Ali Akbar Salehi, said during a news conference in Tehran with head of the IAEA, Yukiya Amano.
"I have received permission for inspectors to visit the Arak heavy water plant and the Gachin mine, which has been requested by the agency, and Iran has voluntarily announced its readiness for this," ISNA quoted Salehi as saying.
Amano said the agreement would be followed by the implementation of a number of practical steps in the next three months. He described the framework as an important step forward but there was "still a lot of work to be done", ISNA reported.
The agreement is intended to set up an inspection regime to allow the IAEA to ascertain whether Iran's nuclear programme is for peaceful purposes only, a claim offered repeatedly by Iranian officials.
It has asked for access to sites, officials and documents in Iran as part of its inquiry.
