A spokesman for the Iranian Atomic Agency has announced that representatives of the International Atomic Energy Agency are scheduled to arrive in Tehran on January 18 to initiate the first steps in implementing the Geneva agreement.

Meanwhile, the U.S. president once again urged Congress to refrain from imposing fresh sanctions on Iran and give the agreement a chance.

Obama added that he is prepared to veto any new sanctions approved by Congress.

Iran has agreed to greater IAEA supervision over its nuclear program and the suspension of uranium enrichment at the 20 percent level, while world powers have, among other incentives, agreed to refrain from imposing new sanctions on Iran for the next six months.

Following the implementation of the Geneva agreement, the parties reportedly will meet in February to finalize a more comprehensive deal to end the disputes over Iran’s nuclear activities.
