The Trans-Caspian International Transport Route (TITR) runs through China, Kazakhstan, the Caspian Sea, Azerbaijan, Georgia, Turkey and further through the Black Sea to Europe. The TITR is a multimodal route that involves two modes of transport: rail and sea.

Geographically and historically, transport and trade have united Eurasia as much as geopolitical conflicts and imperial rivalries have kept it fragmented. Since the 2000s and even more so with the launch of the Belt and Road Initiative (BRI) and the Eurasian integration (EAEU) in progress, opportunities for a major diversification and modernization of the economies of continental Eurasia via transport and trade integration, at both a regional and global level, have risen dramatically and have in fact never been greater.
