BRUSSELS  Iran said Friday that it would resume talks with the West about its nuclear program in November, according to officials at the European Union.

In a two-paragraph letter answering an invitation offered more than three months ago by the bloc’s foreign affairs chief, Catherine Ashton, the Iranians said their senior negotiator, Saeed Jalili, could hold discussions as of Nov. 10. Iran’s president, Mahmoud Ahmadinejad, said last month in New York that Iran was prepared to resume talks, but gave no specifics.

An actual date and location must still be agreed on for the talks, which would include Ms. Ashton, who took over in December as the European Union’s foreign policy chief, and senior officials from the United States, Russia, China, France, Germany and Britain.

Ms. Ashton called the Iranian agreement “very important,” but given the tortuous path of past talks, there was no sense that it signaled any breakthrough.
