Asserting that Iran would continue to share in expertise in the nuclear field with other countries, its former president Mohammad Khatami on Friday said Iran's cooperation with Pakistan in this area would "never ever" be a source of threat to India.

"I give you the guarantee that Iran would never like any country to be a threat to any other country," Khatami said while addressing India Today Conclave 2007 on 'Challenges For The Brave New World.'

Khatami said though it does not have any "special cooperation" with any country, it will certainly "take advantage of existing experience in this respect wherever it might be" in the legitimate scale.

"Science does not set any limits to any country, wherever it might be, we have to get access to it," he said adding, this "does not mean we have necessarily any special cooperation on nuclear issue with any special country."

"I would give the guarantee that this technology would never be a threat to any country," Khatami said, responding to a question on the issue.

Terming India and Pakistan as "the good great countries and two friends of Iran," the former president wished the two nations would focus on "the common interests" and are no threat to each other.

Championing the cause of peaceful use of nuclear energy, Khatami also hoped to see "the whole earth as well as Middle East as a nuclear free world."
