In an interview with Russia 24 TV channel, Yukiya Amano, who visited the Russian Federal Medical-Biological Agency earlier in the day, said Russian authorities paid much attention to the development of advanced nuclear technologies used in the medical sphere.

Russia also takes a great interest in cooperation with the IAEA on the issue, he said, adding that this cooperation would continue.

More that 60 countries have been seeking to develop atomic energy, and 30 countries who already have nuclear technology would like to extend its use, Amano said.

The IAEA can help those countries in creating a reliable nuclear infrastructure, and Russia, which has a "systematic" approach to nuclear technology, may play a "very important role" in this process, he added.

Earlier this week, Amano, who is paying his first visit to Russia, met with the head of Russian state-run nuclear corporation Rosatom and a number of Russian top officials, including Prime Minister Vladimir Putin.
