South Korea considers phased support for US-led Strait of Hormuz security mission

South Korea's Defence Minister announced the country is reviewing a phased contribution to US-led efforts ensuring safe navigation through the Strait of Hormuz, following a ship attack in the region.

The support would fall short of direct military participation, reflecting Seoul's cautious approach to regional security tensions.

  • About one-fifth of the world’s oil passes through the Strait of Hormuz each day, making it one of the most strategically important maritime routes on Earth.
  • The strait is only about 21 miles wide at its narrowest point, which heightens the risk of disruption from conflict or accidents.
  • Iran has repeatedly threatened to close the Strait of Hormuz during past tensions, raising concerns among major oil‑importing countries.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
