"When I was in Egypt ... it was suggested that the next meeting be held in Cairo," Iranian Foreign Minister Ali Akbar Salehi was quoted as saying by ISNA on Wednesday. "This issue was welcomed by our dear friends in Egypt and Egypt will consult with the P5+1 for hosting this meeting."

The last round of negotiations between Iran and six world powers, known collectively as the P5+1, over Tehran's disputed nuclear programme was held in June 2012 in Moscow. Iranian media last week cited Geneva, Istanbul and "some other cities" as possible locations for talks.

Both Iran and P5+1 - the United States, Britain, France, Germany, China and Russia - say they want to resume talks.

However, the two sides' priorities diverge: the powers want to curb Iran's work to potentially develop atomic weapons, while Iran wants sanctions scrapped and their "rights" to enrich uranium formally recognised.

Three rounds of negotiations in 2012 failed to achieve a breakthrough in the decade-old dispute, which has the potential to trigger a new Middle East war. Iran denies it is pursuing weapons and says its programme is purely peaceful.
