TEHRAN, Jan. 27 -- Iran and the world powers will resume nuclear negotiations in New York in February, the official IRNA news agency reported on Monday.

"The negotiations between Iran and the P5+1 group will be held in New York to the end of (the Iranian month of) Bahman (before Feb. 19), which aims at reaching a final agreement," a source close to Iranian nuclear negotiating team was quoted as saying by IRNA.

"In the upcoming talks in New York, Iran's Foreign Minister Mohammad-Javad Zarif, the European Union foreign policy chief Catherine Ashton and the representatives of the P5+1 group will partake," the source said.

The meeting will seek to decide on the agenda of the talks, to specify the level of the negotiations and to discuss the mechanism to reach the final agreement, he added.

"If it is necessary, the upcoming talks will be confidential; since the real and serious negotiations remain confidential," he said, adding that "However, the results will be announced clearly. "

If any sanctions, under any pretext, are imposed against Iran by the U.S. Congress, it would mean violation of the Geneva deal and the United States will be responsible for the failure of the agreement, he said.

In the meantime, "the Geneva deal does not mean the normalization of relations with the United States," he said. "The enmity of the United States with Iran is already there," he noted.

On Jan. 20, Iran and the P5+1 group, including the United States, Russia, China, France, Britain and Germany, started the implementation of the first step of the Geneva interim deal clinched on Nov. 24, 2013.

As a part of the interim deal, Iran suspended 20 percent uranium enrichment as of Jan. 20. Iran also started the process to dilute and oxidize its 196-kg-stockpile of 20-percent enriched uranium.
