Two alternative trade corridors have been especially propelled.
The first is the Middle Corridor (or the Trans-Caspian International Transport Route), a multi-modal land, rail, and sea route between China and Europe that passes through Central Asia, the Caucasus, and Turkey.
The second is the Four Seas Initiative, a framework linking the Persian Gulf with the Caspian, Mediterranean, and Black Seas via a Syria-Turkey transit corridor.
I believe one of these routes will be built to reduce Iranian power over oil.
