Kazakh President Nursultan Nazarbaev is visiting Turkmenistan.
Nazarbaev is scheduled to hold talks on December 2 with Turkmenistan's president, Gurbanguly Berdymukhammedov, mainly on bilateral ties.
According to the Kazakh presidential press service, Nazarbaev, Berdymukhammedov, and Iranian President Hassan Rohani will participate in the ceremony marking the opening of a railway line linking the three countries on December 3.
Authorities say the Ozen-Bereket-Gorgan railway line will reduce travel time for passengers and cargo between the three Caspian Sea states.
