Iran agrees to UN nuclear watchdog's access: statement
President Hassan Rouhani (R) meeting with Director General of the International Atomic Energy Agency (IAEA) Rafael Mariano in Tehran.
"Iran is voluntarily providing the IAEA with access to the two locations specified by the IAEA," the two sides said in a joint statement, adding they had agreed on dates for the access and the verification activities there.
IAEA Director General Rafael Grossi travelled to Tehran this week in the Argentine's first visit there since taking on the top post at the agency last year.
"Both sides recognise the independence, impartiality and professionalism of the IAEA continue to be essential in the fulfilment of its verification activities."
The IAEA monitors Iranian atomic activities on the ground with a 2015 landmark accord curbing Tehran's nuclear programme in exchange for sanctions relief.
The agreement has been faltering since US President Donald Trump pulled out of it in 2018 and re-imposed sanctions with remaining participants -- China, Britain, France Germany and Russia -- struggling to save it.
Access to the two disputed sites had been blocked for months, prompting a diplomatic row.
After meeting Grossi, head of Iran's atomic agency, Ali Akbar Salehi, said a "new chapter" had started.
