U.S. seized an Iran-bound ship with suspected dual-use cargo even as freight traffic between China and Iran along an overland rail corridor has increased. U.S. military has been enforcing a naval blockade in the Strait of Hormuz even during the ceasefire.

Fox News reported that the growing China-linked rail traffic is giving Tehran a workaround that Washington cannot easily shut down without risking a wider conflict. Cargo trains running from central China to Iran jumped from roughly one per week before the blockade to one every three or four days, according to Bloomberg. The overland rail corridor runs through Kazakhstan and Turkmenistan.

U.S. Navy. Isaac Kardon, a senior fellow focused on Chinese strategy and maritime security, told Fox News Digital there is no substitute for a very large crude carrier.

Kardon estimated that maybe like 1% of the exports that Iran would typically be pushing out through Hormuz could go over land.

U.S.

Naval enforcement, Meizlish said. Isaac Kardon pointed to potential movement of parts for drones and missile precursor chemicals along the rail corridor. Even so, Kardon emphasized the corridor cannot sustain large-scale economic or military flows.

Pressure at sea.
