White House officials said President Obama's willingness to reach out to the two countries has gotten results, The Washington Post reported.

"Today's overwhelming vote at the IAEA's Board of Governors demonstrates the resolve and unity of the international community with regard to Iran's nuclear program," the White House spokesman, Robert Gibbs, said. "Indeed, the fact that 25 countries from all parts of the world cast their votes in favor shows the urgent need for Iran to address the growing international deficit of confidence in its intentions."

In September, it was revealed Iran had a second uranium enrichment facility, heightening Western fears about Tehran developing the capacity to build a nuclear weapon.

Gibbs said if Iran truly intends to use its nuclear program for peaceful purposes, the United States is prepared to work toward a diplomatic solution on the matter.
