Behrouz Kamalvandi, who is the director of international, legal and parliamentary affairs at the Atomic Energy Organization of Iran (AEOI), said on Friday that a recent remark by U.S. Secretary of State Marco Rubio that only countries that have nuclear weapons carry out enrichment was wrong.

The official said that countries like Belgium, the Netherlands, South Korea, Japan, Argentina, and Germany do not possess nuclear arms but they enrich uranium.

U.S. officials, he said, must study the subjects that they speak about before they speak about them.
