"The IRISL signed the memorandum of understanding (MOU) with Japan's Suzue Corporation and Kamigumi in Singapore, Iran's Maritime News Agency reported on April 4. Under the deal, the sides will survey grounds for cooperation in construction of dry ports and investment in Iran's port terminals. Once the preliminary studies are completed, the sides will sign an operational contract." (April 2017)
