U.S. Secretary of State Marco Rubio said that if Iran controlled the Strait of Hormuz, it would set a dangerous precedent. Rubio linked the issue to wider maritime tensions in Asia, including disputes involving China and ASEAN members in the South China Sea.

The statement matters because the Strait of Hormuz is one of the world's most sensitive maritime chokepoints. Any claim of control over such a passage raises questions about freedom of navigation, regional security, and the security of energy and trade routes.
