The European Union confirmed Wednesday afternoon that Iran's chief nuclear negotiator had replied to the letter EU foreign policy chief Catherine Ashton sent him in October offering to re-open talks on Iran's nuclear program.

"We have received the letter from Dr. [Saeed] Jalili today...We are carefully studying the letter and consulting with our" partners, Maja Kocijancic, spokeswoman for Ashton said in a statement.

She had no comment on the contents of the letter. One EU diplomat, who had seen the letter, said Jalili had sent a one page response to Ashton.

The EU has said it can only restart talks if
Iran pledges to engage seriously with the concerns about its nuclear program. The U.S. and many EU countries have accused Tehran of seeking to build nuclear weapons, a charge that Tehran denies.

The news came as Iranian state media reported that the country plans to cut oil supplies to six European Union countries in response to a crude oil export ban the EU agreed to in January.
The embargo takes full effect in July.
