Iran Warns South Korea Against Joining US-Led Military Operations in Strait of Hormuz
REL_TIME: 09 Sep 2026 14:12Z · LANG: EN
Iran has issued multiple stern warnings to South Korea, stating that any military deployment or operational involvement in the Strait of Hormuz would be treated as direct participation in the war against Iran and an act of military aggression. The warnings—delivered via media interviews and directly in Korean on social media by Iranian Foreign Ministry spokesperson Esmaeil Baqaei—come as Seoul faces mounting pressure from US President Donald Trump to contribute naval and reconnaissance assets to multinational maritime security operations. While South Korea reviews options such as deploying maritime patrol aircraft, logistics vessels, or mine-clearing personnel, Seoul emphasizes that no final decision has been reached and that domestic defense readiness remains its top priority.
// Background
The Strait of Hormuz is a vital global energy transit chokepoint responsible for approximately one-fifth of global oil and liquefied natural gas shipments, including over 60 percent of South Korea's crude oil imports. Following the outbreak of hostilities between the United States, Israel, and Iran on February 28, maritime traffic through the strait was disrupted as Iran imposed restrictions and the US deployed over 20 warships to enforce blockades and escort operations. Under sustained pressure from Washington to shoulder collective security burdens, Seoul has been evaluating potential roles, including maritime surveillance via P-8A aircraft and logistics support, while navigating domestic political divisions and diplomatic friction with Tehran.
// Key Developments
- Tehran explicitly stated that any South Korean military presence in the Persian Gulf or Strait of Hormuz would be viewed as direct support for US aggression.
- Iranian Foreign Ministry spokesperson Esmaeil Baqaei published a Korean-language warning on X, citing 64 years of bilateral ties while cautioning against bowing to US pressure.
- Iranian academic and advisor Mohammad Marandi warned that South Korean economic and civilian assets in Gulf nations could become targets of retaliatory strikes.
- The US administration continues pressing Seoul to commit resources to the waterway, noting South Korea's heavy reliance on Gulf oil, which accounts for over 60 percent of its crude imports.
