Javad Vaeidi of the Iranian National Security Council denied that Russia is threatening to stop cooperation on building a nuclear power plant at Bushehr in an effort to push Tehran into accepting the enrichment plan.
Vaeidi also rejected the European Union's 7 January warning to Iran not to resume research work. Some Western powers suspect Iran's enrichment program is aimed at developing nuclear weapons -- which Iran denies.
Iran has also been criticized by the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), for a number of failures to disclose information relating to nuclear activities.
