The United States will face significant legal hurdles in justifying a maritime blockade affecting Iranian ports on both sides of the Strait of Hormuz, said Subeom Choi, secretary general of the Korea Arctic Shipping Association.
Choi cited the traditional requirements governing naval blockades: prior notification, effective enforcement, impartial application and due regard for humanitarian considerations. He said the legal defensibility of a unilateral blockade of Iranian ports is highly questionable.
The comment lands amid uncertainty over how long ongoing military tension around Hormuz will continue to disrupt civilian commercial shipments. The Strait remains a critical chokepoint through which roughly a quarter of global crude oil and large volumes of LNG transit.
The Korean executive's warning shows that Asian carriers are foregrounding international maritime law alignment in their blockade-risk assessments. Insurance and P&I clubs are expected to lift premiums on routes touched by enforcement.
Several Asian shipowners are temporarily re-routing certain shipments. Which countries and cargo types the blockade ultimately covers will be shaped by diplomatic and legal arguments still unfolding.
Key Takeaways:
1. Subeom Choi: a unilateral U.S. blockade of Iranian ports is legally questionable.
2. Traditional maritime law requires notification, effectiveness, impartiality and humanitarian regard.
3. The Strait of Hormuz handles roughly a quarter of global crude oil flows.
4. P&I insurers are set to raise premiums on enforcement-affected routes.
5. Asian carriers are temporarily re-routing some shipments amid the legal uncertainty.
