The United States says world powers will begin a new phase of talks with Iran next month on reaching a long-term nuclear deal.
U.S. State Department spokeswoman Jen Psaki says the talks likely will begin in mid-February, and will be held in New York.
She says Iran and the European Union have agreed to hold the talks in the United States, rather than in Geneva, where the last round of talks took place. She said New York was chosen because it has a similar international "support structure" to Geneva.
The last round of negotiations led to an interim deal in which Iran agreed to stop enriching uranium that could be used in a nuclear weapon. In exchange, the United States and European Union are easing some sanctions against Iran.
That agreement will last for six months while talks continue on a permanent deal.
The nuclear talks involve Iran, Germany and the five permanent United Nations Security Council members - Britain, China, France, Russia and the United States.
The United States has accused Iran of trying to build a nuclear bomb. Iran insists its nuclear program is strictly for peaceful civilian purposes.
