The United States, the United Kingdom, and Australia have reached an agreement on a new Indo-Pacific security treaty.

As part of the AUKUS arrangement, Australia will receive nuclear-powered submarines, which is considered as a move to confront China.

In an apparent move to challenge China, Australia, the United States, and the United Kingdom have established a new trilateral security partnership, including a coordinated effort to assist the Australian military in acquiring nuclear-powered submarines.

On Wednesday, the leaders of the three countries revealed the AUKUS alliance. They emphasized that the submarines would be nuclear-powered but would not carry nuclear weapons.

Australia has signed the Treaty on Non-Proliferation of Nuclear Weapons (NPT).

US President Joe Biden, who was virtually joined by Australian Prime Minister Scott Morrison and his UK colleague Boris Johnson, said the three countries were taking a "historic step" to deepen their cooperation.

US President Joe Biden, who was virtually joined by Australian Prime Minister Scott Morrison and his UK colleague Boris Johnson, said the three countries were taking a "historic step" to deepen their cooperation.

“We all recognize the critical importance of sustaining long-term peace and stability in the Indo-Pacific,” Biden stated from the White House.

“We must be ready to handle both the existing strategic situation in the region and how it may change, because the future of each of our nations – and indeed the world – is dependent on a free and open Indo-Pacific that endures and thrives in the decades ahead.”

In their remarks on Wednesday, the three presidents did not expressly reference China.

A representative for the Chinese embassy in Washington, DC, said shortly after the announcement that the three countries should “shake off their Cold War attitude and ideological prejudice,” according to the Wall Street Journal and Reuters news agencies.

The spokesman condemned what he called "exclusionary blocs" that sought to exclude other countries' interests.
