South Korea is considering sending military assets to the Strait of Hormuz, the critical waterway connecting the Persian Gulf to the Arabian Sea through which roughly a fifth of the world's oil supply passes, according to South Korean media reports and a presidential office official. Seoul confirmed Friday that a review is under way, though no final decision has been reached.
A senior presidential official, speaking on condition of anonymity, said South Korea may be able to contribute to international efforts to ensure freedom of navigation through the strait — but only within limits that do not compromise the country's defence readiness on the Korean Peninsula. "In order to make tangible contributions to the Strait of Hormuz, this should first be considered in light of our readiness posture on the Korean Peninsula, as well as in accordance with local legal procedures," the official said. Crucially, the official stressed that any contribution need not take a combat form, noting that noncombatant roles, search operations, and a combat support ship are all among the options under comprehensive review.
The deliberations come against a backdrop of sustained pressure from US President Donald Trump, who has repeatedly accused Seoul of turning down his requests for military involvement in the waterway. Tensions in the region have been running high for months: Iran's army has reportedly targeted US bases in the United Arab Emirates and Kuwait, and US Vice President JD Vance has declined to formally describe the ongoing conflict with Iran as a war, even as clashes continue six months after hostilities began. Israeli Prime Minister Benjamin Netanyahu has meanwhile claimed Iran's Islamic Republic is "weaker than ever."
The presidential official denied that the Hormuz deployment question has derailed broader Seoul–Washington negotiations, which include an economic and defence agreement tied to a wider tariff deal. However, the official acknowledged that those talks are not progressing smoothly, with semiconductor trade policy also on the table following US Commerce Secretary Howard Lutnick's remarks this week about developing a "targeted" tariff approach for the sector.
Why this matters: South Korea's potential deployment would mark a significant step in its involvement in Middle Eastern security affairs, driven by its alliance obligations to Washington and its own dependence on Gulf energy supplies. The careful framing around non-combat roles reflects Seoul's need to balance US alliance demands against domestic legal constraints — any troop dispatch requires parliamentary approval — and the ever-present security calculus on the Korean Peninsula.
