US, UK & Australia Address Iran War and Strait of Hormuz Energy Crisis

International Response to the Strait of Hormuz Crisis

By Kanishka Singh

Diplomatic Discussions and Statements

WASHINGTON, May 11 (Reuters) - U.S. Secretary of State Marco Rubio held separate calls with his Australian and British counterparts on Monday to discuss Iran and the Strait of Hormuz, the State Department said.

Key Points from the State Department

Here are some details:

Freedom of Navigation and Energy Market Disruption

• Rubio discussed "Iran and ongoing efforts to restore freedom of navigation in the Strait of Hormuz," the State Department said in separate statements after his calls with Australian Foreign Minister Penny Wong and British Foreign Secretary Yvette Cooper.

• The Iran war has effectively closed the strait and caused the biggest disruption to the energy market in history.

• Before the war, about 20% of global oil and liquefied natural gas shipments passed through the strait.

• Iran has blocked nearly all ships passing through the strait apart from its ​own.

Sanctions, Blockades, and Military Actions

• President Donald Trump has imposed ​a separate blockade of Iranian ports.

• Trump has repeatedly said Washington's Western allies have not been doing enough to back the U.S. in the war, which began when the U.S. and Israel attacked Iran on February 28.

• ⁠Iran responded with strikes on Israel and Gulf states that host U.S. bases. U.S.-Israeli strikes on Iran and Israeli attacks in Lebanon have killed thousands and displaced millions.

• Trump said on Monday that a ceasefire with Iran, which was reached more than a month ago, was "on life support."

• The U.S., Australia and the UK have imposed sanctions on Iranian networks and individuals both during and before the war.

  • The Strait of Hormuz is a critical chokepoint: about one‑fifth of global petroleum and LNG trade passes through it, and its partial closure during the Iran war has drastically disrupted global energy markets (iea.org).
  • In tandem with diplomatic outreach, the U.S. and UK have imposed targeted sanctions on Iranian networks facilitating hostile activity and sanctions evasion, while the U.S. Treasury is urging banks to flag suspected Iranian money‑laundering operations (apnews.com)
