Iran's President Mahmoud Ahmadinejad said in Tehran that the construction of a railroad linking Iran to Turkmenistan and Kazakhstan is a “vital project” and urged Turkmen and Kazakh presidents to push for its speedy implementation. In 2007, the three countries signed an agreement to construct the 920-kilometer railway, although the work has not yet begun.
When constructed, the railroad will connect Iran to Turkmenistan and Kazakhstan, and on to Russia and China, and eventually serving as a transportation link between China and Europe.
