TEHRAN, Iran - France rejected Iran's request for more talks on the Islamic republic's nuclear program, saying today that Tehran first must suspend its atomic activities.

Iran asked for a ministerial-level meeting with France, Germany, Britain and the European Union, but its decision to resume some uranium enrichment-related activities “means that it is not possible for us to meet under satisfactory conditions to pursue these discussions,” French Foreign Ministry spokesman Denis Simonneau said in Paris.

“Iran must return to a complete suspension of these activities.”

U.S. Undersecretary of State Nicholas Burns supported the idea that Iran should suspend its program and return to talks.

“There is a consensus that Iran should turn back, return to negotiations and suspend its nuclear program,” Burns told reporters in Bombay, India, during a South Asia tour. “But that's not the path Iran is on now.”

The Bush administration sent Burns to London to coordinate a strategy with Britain, China, France, Germany and Russia on dealing with Iran. Burns conceded differences remained after Tuesday's meeting.

“We reached a consensus on some points ... others need to be worked on,” he said.

Burns repeated U.S. demands that the U.N. nuclear watchdog agency refer Iran to the Security Council - where it could face sanctions - for resuming research on centrifuges used in uranium enrichment. Russia and China oppose sending Iran to the Security Council.

Earlier today, Iran's foreign minister told state radio the nation's chances of being referred to the Security Council were slim. Manouchehr Mottaki did not give a reason for his view, but emphasized that Iran wanted to restart negotiations with Britain, France and Germany.

The European states, with U.S. backing, were calling for a Feb. 2 meeting of the International Atomic Energy Agency to discuss taking action against Iran following Tehran's decision earlier this month to resume small-scale enrichment of uranium - a process that can produce material for atomic reactors or bombs.
