France has asked Iran to respect the UN resolutions on its nuclear program and to suspend the construction of a new uranium enrichment site, the French Foreign Ministry said on Monday. 'We are waiting that Iran will act in conformity with its international obligations by making the suspension of all uranium enrichment activities ... We are waiting that Tehran will cooperate and finally agree to engage in substantive negotiations with the Six,' the ministry said in a statement. Ali Akbar Salehi, the leader of the Iranian Organization for Atomic Energy, announced late Sunday the construction of a new uranium enrichment plant scheduled for next year, turning a deaf ear to UN sanctions threats. The UN Security Council adopted in June a resolution on the Iranian nuclear issue, asking Teheran to suspend all enrichment- related activities and stop the construction of any facility for enriching uranium. 'The announcement (of the) construction of a new uranium enrichment site in the first half of 2011 only aggravates the international community's concerns over Iran's nuclear program,' the ministry added. The United States and its Western allies are worried that Iran would use the uranium enrichment technology to make nuclear weapons, but Tehran has insisted that its nuclear program is for peaceful purposes only.
