The remarks by negotiator Abbas Araghchi on Iranian state TV reflect the scope of the possible first steps in a deal aimed at easing Western concerns that Iran could one day make a nuclear weapon, an assertion Iran strongly denies.
Iran seeks a rollback in US-led sanctions on oil exports and access to international banking systems. Envoys for the US and other world powers want to trim Iran's uranium enrichment.
Araghchi repeated today that Iran would never halt its enrichment programme, but would discuss setting levels. He noted a "probability" of accord emerging from the current round, which opened yesterday.
