“I must say that the duration of the negotiations constitutes a red line.
The negotiations should not be lengthy,” Rowhani said on his return from talks in Brussels with the foreign ministers of Germany, France and Britain, and European Union foreign policy chief Javier Solana.
He said Iran would not allow the negotiations to last “too long or be deviated from the main issues, or for a country to try to waste time.”
“We have reminded the Europeans that the duration of the negotiations should not be too long and that the suspension of (uranium) enrichment is valid only for the duration of the negotiations,” Rowhani added.
Iran has said a first evaluation of the negotiations with the European Union would be carried out after three months.
The talks opened Monday with the focus on giving Tehran the trade, technology and security rewards in return for suspending uranium enrichment activities under an agreement struck last month in Paris.
