Iran’s new foreign minister has reaffirmed the need for sustainable regional security with the participation of the countries of the region, stressing there will be no security as long as foreign countries interfered in the Middle East. “What we need more than ever today is ‘sustainable regional security’ with the participation of the countries of the region,” which can materialize through using economic resources towards promoting peace and development, Hossein Amir-Abdollahian said on Saturday.
