Majlis Speaker Ali Larijani says many economic problems are not due to sanctions, but they are rooted in mismanagement. “I do not believe that all problems are due to sanctions, but many economic problems stem from mismanagement. Today, our economy is suffering from this issue that should be resolved,” the Fars news agency quoted him as saying on Thursday. He said the main economic challenges facing the country are reliance on oil revenue, low productivity and government’s excessive involvement in development projects.
