European Union officials are concerned that Iran is expecting too much, too soon from a November agreement to suspend uranium enrichment in exchange for economic incentives.

The growing unease follows a meeting this week between Javier Solana, the EU's foreign policy representative, and Gholamreza Aqazadeh, head of Iran's Atomic Energy Organisation, and a Financial Times interview with Hossein Mousavian, Tehran's chief nuclear negotiator. In both, Iran called for speedier, more concrete benefits in trade and technological ties from its talks with France, Germany, the UK and Mr Solana.
