A draft of the final communiqué also said the G8 remained open to dialogue with Tehran, which denies widespread western charges that it is seeking to make atomic weapons. The G8 ministers will end a two-day meeting in Canada on Tuesday. A copy of the communiqué, dated Monday, was shown to Reuters. The document is the latest step in a campaign of pressure by many of the world's most powerful nations to force Iran to comply with demands from the U.N. Security Council and cooperate with the International Atomic Energy Agency. "Iran's continued noncompliance with its United Nations Security Council and IAEA obligations regarding its nuclear program is of serious concern to G8 ministers," said the final communiqué. "Ministers agreed to remain open to dialogue and also reaffirmed the need for the international community to take appropriate and strong steps to demonstrate ... resolve to uphold the international nuclear nonproliferation regime."
