The UAE has signed onto the US-led shipping defence coalition, while Australia has tempered its commitment.

Last week, the Middle East Gulf state announced it had joined the International Maritime Security Construct (IMSC), which aims to uphold freedom of navigation in and around the Strait of Hormuz.

The Emirati commitment "comes in support of regional and international efforts to deter threats to maritime navigation and global trade, and in order to secure the flow of energy supplies to the global economy and contribute to the maintenance of international peace and security," a statement from its Ministry of Foreign Affairs and International Cooperation read.
