Iran sought to reassure investors of its commitment to unveil new and improved oil contracts, downplaying domestic opposition to the return of international energy companies. Mohammad Nahavandian, President Hassan Rouhani’s chief of staff, told the Financial Times in an interview that the lifting of sanctions was a “win-win” situation for Iran and the west and that it wanted “constructive interaction” with the outside world. “We have to think about the future, and co-operation between the Iranian economy and the outside world would be beneficial to us all,” he said. Iran’s oil ministry cancelled a long-awaited conference to publicise a new contract for international oil companies in London last month after it was attacked by Mr Rouhani’s opponents as an attempt by international oil companies to loot Iran’s natural resources. Mr Nahavandian said that the Rouhani administration was working with its critics to resolve the issue. “The government has decided to go ahead with the expansion of the oil industry and foreign investment is required for this. We have revised the framework of the [oil] contracts,” he told the FT.
