Iranian President Mahmoud Ahmadinejad has welcomed a proposal by world powers to defuse a standoff over Tehran's nuclear activity as a positive step. However he gave no sign when an answer would come.
Mr Ahmadinejad, markedly more upbeat about the proposal on a trip to China than he has been at home, said Iran was examining the offer of incentives for Tehran to stop enriching uranium.
He also warned Iran would not be concerned by possible sanctions if it rejects the 6 June offer.
Washington confirmed yesterday that penalties originally put into the package were left out when it was handed to Tehran.
