Prior to his departure from Tehran earlier today, Ahmadinejad, who himself holds a PhD in civil engineering, noted the two countries\' abundant joint ventures and projects, including the Sangtude-2 Dam, and praised Iranian engineers for their exceptional expertise and for their proper and skillful application of the hi-tech in constructing the dam. Tajik officials and people are happy to see that the project is accomplished even 6 months ahead of the declared timetable. The construction project of the dam on Vakhsh river as well as its 220-megawatt power plant called Sangtuda-2 started by an Iranian company in early 2006. Management of the dam which will produce one billion kw/h electricity once fully implemented will go to Tajikistan after 12 years of implementation by Iran. Ahmadinejad is also due to finalize a contract on the construction of Eini power plant near Zarafshan river during his visit to the Central Asian state.
