Australia’s AUKUS Submarine Deal Under Increased Scrutiny Amid Shifting Global Alliances

by Team Confer · April 9, 2025

Australia’s plan to acquire nuclear-powered submarines under the AUKUS agreement is facing increased scrutiny amid shifting global alliances. The AUKUS pact, established in 2021 between Australia, the United Kingdom, and the United States, aims to bolster security in the Indo-Pacific region by providing Australia with advanced submarine capabilities. However, this initiative has drawn criticism from various international actors, including China and France, who express concerns over regional stability and the exclusion from the deal.

China has condemned the AUKUS agreement, stating that it undermines regional peace and stability and reflects a “Cold War mentality.” Similarly, France reacted strongly to Australia’s cancellation of a previous submarine contract in favor of the AUKUS deal, describing the move as a “stab in the back” and recalling its ambassadors from the U.S. and Australia in protest. These reactions highlight the complex geopolitical implications of Australia’s submarine acquisition and the broader realignment of international partnerships.

Context & Background

The AUKUS agreement, announced in September 2021, is a trilateral security partnership between Australia, the United Kingdom, and the United States. Its primary objective is to enhance security in the Indo-Pacific region by equipping Australia with nuclear-powered submarines. This move is seen as a strategic response to China’s growing influence and military presence in the area.

The pact has led to significant geopolitical tensions. France, which had a prior agreement to supply Australia with conventional submarines, was notably aggrieved by the abrupt cancellation of its contract, leading to a diplomatic rift. Additionally, China’s condemnation of the deal underscores the broader concerns about an escalating arms race and the potential for increased militarization in the Indo-Pacific region.
