The United States issued new maritime guidance for commercial vessels transiting the Strait of Hormuz as tensions with Iran escalate over its nuclear program. The Maritime Administration advised U.S.-flagged ships to maintain maximum distance from Iranian territorial waters while avoiding navigational hazards. Vessels should verbally decline boarding requests from Iranian forces.

The advisory comes amid heightened concerns about potential disruptions to Middle East oil supplies through the strategic waterway. Iran has previously threatened to close the strait and has seized commercial ships alleging smuggling violations. The guidance specifically instructs crews not to forcibly resist if Iranian forces board their vessels.

Diplomatic efforts continue with nuclear talks mediated by Oman showing initial progress, though Washington seeks broader agreements on Iran's ballistic missiles and regional activities. President Trump recently imposed 25% tariffs on countries purchasing Iranian goods, adding economic pressure to the negotiations. The maritime guidance reflects growing security concerns as diplomatic channels remain active but fragile.
