A South Korean container ship has set sail for Europe via the Arctic's Northern Sea Route, testing whether the passage can become a viable alternative to the traditional Suez Canal route.

The trial voyage comes as shipping companies seek new trade corridors amid disruptions affecting key global maritime routes.

The journey is expected to cut transit times significantly, but experts warn that seasonal ice conditions, reliance on Russian services and growing environmental concerns could limit the route's long-term potential.

The voyage will provide crucial data on costs, fuel use and commercial feasibility.
