President Rouhani said that foreign investors are welcome to invest in construction of Iran's railroad projects.
He underlined immediate execution of the Iran-Turkmenistan-Kazakhstan railway as well as the Khaf-Herat railway which will link East of Iran to Afghanistan.
Iran-Turkmenistan-Kazakhstan railway is a part of the North-South international transport corridor.
Turkmenistan announced in January that it will complete its own section of the Iran-Turkmenistan-Kazakhstan railway by October 2014.
