The Foreign Ministry spokesman said Tuesday the issue of nuclear exchange for Tehran’s research reactor is still open to talks.

According to IRNA, Ramin Mehmanparast made the remarks at his weekly press briefing.

Mehmanparast's remarks were the answer to a question on what Iran's response would be to the West-incited tension on producing 20% enriched nuclear fuel.

Mehmanparast said the 20% enriched uranium program is performed within the framework of Iran’s peaceful nuclear activity.
