After marathon talks in the Austrian capital, an accord was reached on Tuesday aimed at ending the 13-year standoff over Iran's nuclear ambitions, following repeated diplomatic failures and threats of military action.
“This historic agreement will benefit the international community, the Middle East and Iran,” Brende said in a statement. “It will also pave the way for closer political and economic contact with Iran.”
He predicted that the easing of sanctions would present business opportunities for Norwegian businesses, but said it was up to the companies themselves to make the decision.
“We must leave the assessment of the opportunities and risks of increased cooperation with Iran to the companies,” he said.
“This is good news,” Tommy Hansen, the press director for the Norwegian Oil and Gas Association. “Iran is a large market, which require both technology and expertise after years of sanctions. This is an opportunity for Norwegian companies.”
The oil services and engineering company Aker Solutions said last week that it was interested in resuming operations in Iran should sanctions be lifted.
But Statoil, which holds an exploration license for Iran's Khorramabad block, and worked as the offshore operator for the development of phases 6, 7 and 8 of the South Pars gas and condensate field, would not comment on whether it planned to return to the country.
A Norwegian court in 2004 found the company guilty of bribing an Iranian official to win the South Pars contract, triggering the resignation of its then chairman and chief executive.
Some oil industry experts predicted that the deal would be negative for Norway's economy, with new oil and gas supplies from Iran further driving down the oil price.
“For Norway's offshore production, it's not that positive,” Thina Saltvedt, an oil analyst at Oslo-based Nordea Markets, told Bloomberg news. “Companies on the Norwegian shelf will face tougher competition because costs must be reduced even further to be competitive internationally.”
Iran has several million barrels of oil in stock, waiting to hit world markets when sanctions are limited.
The deal agreed on Tuesday puts strict limits on Iran's nuclear activities for at least a decade and calls for stringent UN oversight, with world powers hoping that this will make any dash to make an atomic bomb virtually impossible.
In return, painful international sanctions that have slashed the oil exports of OPEC's fifth-largest producer by a quarter and choked its economy will be lifted and billions of dollars in frozen assets unblocked.
The deal — which was built on a framework first hammered out in April — is US President Barack Obama's crowning foreign policy achievement six years after he told Iran's leaders that if they “unclench their fist, they will find an extended hand from us”.
It was hailed by Iran and the European Union as a new chapter of hope for the world but branded a “historic mistake” by the Islamic republic's arch foe Israel.
