In Moscow, Iran's chief nuclear negotiator, Ali Larijani, said there was no need for Tehran to resume a moratorium on uranium-enrichment activity, insisting that all its nuclear activities were "transparent."
He added that Iran agrees to international inspections if they are conducted in line with international law.
"We agree with [International Atomic Energy Agency] inspections and international regulations," Larijani said. "In this regard, therefore, they should not make threats against a country that believes in these regulations. Threats and violent behavior were used in the past and they did not work."
Larijani is in Moscow for talks on a Russian proposal to form a joint venture to enrich Iran's uranium in Russia. The proposal is intended to allay international concerns over Iran's nuclear program.
