Trans-Caspian International Transport Route

The Middle Corridor, also called TITR, is a trade route from Southeast Asia and China to Europe via Kazakhstan, Caspian Sea, Azerbaijan, Georgia and Turkey (optional). It is an alternative to the Northern Corridor, to the north through Russia, and the Ocean Route to the south, via the Suez Canal. Geographically, the Middle Corridor is the shortest route between Western China and Europe. It is undergoing major developments in parts, with the Trans-Kazakhstan railroad completed in 2014 and the Baku–Tbilisi–Kars (BTK) railway operational in 2017.
