Iranian President Mohammad Khatami is due to visit Turkmenistan today. He and Turkmen President Safarmurat Niyazov will attend a ceremony to open a new dam on a river straddling the Turkmen-Iranian border. The Dostluk, or friendship dam, was built on the Tejen River, known in Iran as the Harir-Roud. It is located in the Germab mountain range, some 80 kilometers south of the Turkmen town of Serahs and 250 kilometers east of the Iranian city of Meshed. The joint project will provide both countries with irrigated water and reflects growing ties between Turkmenistan and Iran, especially in the energy sector. Turkmenistan already supplies electricity, generated from some of its natural gas reserves, to northeast Iran.
