Why three governments just froze the same shipping lane

Three coastal states announced, within nine days of each other, that vessels transiting a shared strait would face new mandatory inspection windows. Officially, each cited the same trigger: a near-collision between a container ship and a tanker in March that neither government's existing radar coverage had fully tracked.

What's actually happening is less about that one incident and more about who gets to set the rules for a corridor none of the three fully controls. Each inspection regime uses slightly different criteria, and none of the three governments has agreed to recognize the others' clearances — which means a ship can pass one country's check and still be held at the next.

Shipping lines have started quietly rerouting lower-priority cargo around the strait entirely, adding four to six days per voyage. Insurers have not yet repriced the route, but two major underwriters have added a review clause that takes effect at the end of the quarter.

None of the three governments describes this as a dispute. All three describe it as a safety measure. The gap between those two framings is where the actual story is.
