Business community is upbeat, but the onus is on Tehran to show it is sincere about promoting peace.
There is an obvious and welcome business sentiment in favour of the deal and the business community is already hard at work preparing for when the sanctions finally fall.

The region will only see a genuine new start if Iran changes its aggressive foreign policy.
