Iranian President Mahmoud Ahmadinejad visited Armenia on Monday and struck several agreements to bolster economic ties between the two nations, according to AP. Ahmadinejad and his Armenian counterpart, Robert Kocharian, announced plans to build a railway link and two hydroelectric power plants on the border river, Araks. The agreements are important for landlocked Armenia, which has struggled with power shortages and transport blockades since the collapse of the Soviet Union. Neighboring Azerbaijan and Turkey have shut their borders with Armenia in the wake of a conflict over Nagorno-Karabakh, a breakaway region of Azerbaijan controlled by ethnic Armenians.
