Iran warns against Hormuz Strait crossings without authorisation, Pg16

Key Highlights:

• Iran's Revolutionary Guards issued a warning against any unauthorized crossings of the Strait of Hormuz, stating that non-compliant vessels would be dealt with.
• They asserted that the only authorized route for passage through the Strait is one announced by the Islamic Republic of Iran.
• U.S. Secretary of State Marco Rubio countered, emphasizing that international waterways do not belong to any single nation-state.
• The Strait of Hormuz is a critical global chokepoint, through which approximately 20% of the world's crude oil and a significant portion of liquefied natural gas (LNG) pass daily.
• Iran intends to impose "maritime service fees" for passage, a move the U.S. deems unacceptable for an international waterway.

Detailed Insights:

• The Strait of Hormuz links the Persian Gulf to the Gulf of Oman and the Arabian Sea, serving as a crucial export route for major energy producers including Saudi Arabia, Iraq, Kuwait, Qatar, the United Arab Emirates, and Iran.
• The legal framework governing navigation in such international straits is primarily outlined in the United Nations Convention on the Law of the Sea (UNCLOS).
• UNCLOS Article 38 establishes the right of "transit passage," allowing all ships and aircraft continuous and expeditious passage through international straits without impediment.
• While Iran is a signatory to UNCLOS, it has not ratified the convention and often asserts a right of "innocent passage," which implies a more restrictive regime for foreign vessels.
• The U.S. maintains that the provisions for "transit passage" under UNCLOS have attained the status of customary international law, making them binding on all states regardless of ratification.
• The Gulf Cooperation Council (GCC), comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, was established in 1981 to foster regional coordination and stability.
• Historical tensions over navigation rights in the Strait of Hormuz were prominent during the Iran-Iraq War (1980-1988), also known as the Tanker War.
• Any significant disruption to shipping in the Strait can trigger substantial fluctuations in global oil prices and have widespread economic repercussions.

Key Concepts Involved:

• Strait of Hormuz: A narrow, strategically vital waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea.
• International Waterway: A body of water where vessels of all nations have the right of navigation, typically governed by international law.
• United Nations Convention on the Law of the Sea (UNCLOS): An international treaty establishing a comprehensive legal framework for all marine and maritime activities.
• Transit Passage: The right of navigation and overflight solely for the purpose of continuous and expeditious transit through international straits.
• Innocent Passage: The right of foreign vessels to pass through a coastal state's territorial sea, provided it is not prejudicial to the peace, good order, or security of the coastal state.
