A team from the UN nuclear watchdog will visit Iran on July 11-13 to discuss how to resolve questions about Tehran's disputed nuclear activities, an Iranian official was quoted as saying on Saturday.
But Ali Asghar Soltanieh, Iran's envoy to the International Atomic Energy Agency (IAEA), also indicated the country's co-operation would depend on major powers halting or refraining from further UN sanctions against the Islamic Republic.
President Mahmoud Ahmadinejad separately said "threats and psychological warfare" would not make Iran stop its atomic work, state television reported, the latest defiant statement on the nuclear issue from the Iranian leadership.
Iran says it only aims to produce electricity. But Western countries believe Tehran is seeking a nuclear bomb as it hid sensitive research from the IAEA until 2003 and has stonewalled investigations since then.
"There should be an end to the interference's of the UN Security Council on this issue," Soltanieh told the ISNA news agency in an interview. "If the 5 plus 1 countries make a political decision to stop the Security Council's actions against Iran, we will give the agency ... answers to the remaining questions," he said, referring to the five veto-wielding powers on the UN Security Council plus Germany.
The Vienna-based IAEA last Monday said Tehran had invited it to send the team after Iran's chief nuclear negotiator, Ali Larijani, agreed a "plan of action" for clearing up issues with the agency's head, Mohamed ElBaradei.
"A team ... will come to Tehran to study a working plan that will answer all the remaining issues in regard to Iran's nuclear programme," Soltanieh said in a separate ISNA report.
