US Secretary of State Marco Rubio has called on South Korea and other allied nations to participate in efforts to secure the Strait of Hormuz, arguing that their involvement would yield strategic benefits.

The remarks, delivered in Washington, signal a broadening of the US diplomatic push to counter Iranian influence over the critical energy corridor.

The US government has previously warned that Iranian attempts to impose tolls or exert control over the strait could trigger widespread disruption to global supply chains.

Rubio framed the initiative as a collective security measure, suggesting that allies have a vested interest in maintaining free transit through the waterway.

The appeal comes as shipping traffic through the Strait continues to face headwinds from security concerns.

Recent reports indicate that vessel movements have slowed as operators weigh the risks of transiting the region.
