The official Teheran has confirmed in written form its participation in the construction of the Kajaran tunnel providing all-the-year-round motor communication between Armenia and Iran. According to co-chair of the Armenian-Irani economic cooperation, head of the administration of the RA president Artashes Tumanian, the Irani side has expressed the readiness to provide 85% financing of the tunnel construction. At that, Tumanian refused to mention any terms of the construction until the negotiations on that issue are completed. He noted the importance of the Kajaran tunnel not only for Armenia and Iran but also for the Central Asia states that will have the shortest way to Caucasus and Europe. At the same time, the head of the administration expressed opinion that "there are some difficulties regarding that question as Iran has other neighbors not less important than Armenia". Thereupon he noted the construction of the Kajaran tunnel might be included in the "North-South" project that is an alternative to TRASECA program. So some of the region states included in the program, in particular Azerbaijan and Turkey, actively speak against the Armenian-Irani project. Nevertheless "in general, the process of the project realization is going on successfully". It should be noted the Armenia-Irani agreement on the Kajaran tunnel construction was signed 2001 December. The tunnel will be constructed at a level of 2070 meters under the Meghri pass that is 20 km to the north from the Armenia-Iran border.
