In an interview with the Saudi daily Asharq Al-Awsat, French President Nicolas Sarkozy praised the US president-elect for his intention to seek diplomacy with Tehran.
Obama's statements "reflect our shared views on the necessity of dialogue without concessions with Tehran as the only way to obtain a negotiated end to the crisis," Sarkozy was quoted as saying.
Western countries, headed by the Bush White House, accuse Iran of having plans to develop a military nuclear program.
Tehran, a signatory to the nuclear Non-Proliferation Treaty (NPT), denies the allegation, insisting its activities are directed at the civilian applications of the technology.
President-elect Obama has vowed to "engage in aggressive personal diplomacy" with Iranian officials to resolve the nuclear standoff between Tehran and the West.
The UN agency monitoring the Iranian nuclear program, the International Atomic Energy Agency (IAEA), said in its latest report that it has "been able to continue to verify the non-diversion of declared nuclear material in Iran."
The agency, however, argued that unless Tehran increases its cooperation with the agency, the UN body "will not be able to provide credible assurance about the absence of undeclared nuclear material and activities in Iran."
