Mohammad Eslami made the comments days after the International Atomic Energy Agency’s Board of Governors passed an anti-Tehran resolution.
“We had said (political) pressure and a political resolution will change nothing and that the issuance of the resolution would be followed by serious reaction. That’s why the enrichment of uranium to 60% purity began at Fordow on Monday,” he said on the sidelines of visiting an expo in Tehran on Tuesday.
The draft resolution, ratified on Thursday, criticized Iran for what it called a lack of cooperation with the agency. It was put forward by the United States, Britain, France and Germany, in continuation of their political pressure on Iran. Russia and China voted against the motion.
Iran had already dismissed the resolution as politically-motived and vowed a reciprocal and firm response.
