Australia and Vietnam said they would expand military cooperation as Beijing is expanding its reach in the Pacific Ocean and the South China Sea.
The move comes after talks between Australian Prime Minister Anthony Albanese and Vietnamese leader To Lam concluded in Canberra that the two countries will collaborate more on maritime security and conduct joint training.
“Our defense industries, as well as our defense forces, are cooperating more and more. Today’s uncertain world means that it is more important than ever that friends engage with each other on all levels—economic, social, environmental—to meet the challenges that are before us,” Albanese said.
China’s military build-up in the region has prompted Australia to conduct a once-in-a-generation expansion of its defense forces and a growing U.S. military presence on its territory. Australia’s defense minister, Richard Marles, said cooperation with Vietnam would “directly contribute to the stability and security of our region.” Vietnam is one of the nations with competing claims in the South China Sea, which Beijing claims in nearly its entirety, despite an international ruling that its assertion has no legal basis.
Australia’s expanding defense relationship with Vietnam signals a broader regional effort to strengthen security partnerships as China increases its military and strategic presence across the Indo-Pacific. For Hanoi, closer cooperation with Canberra provides another avenue to improve maritime security and defense capabilities while maintaining its longstanding strategy of balancing relations with major powers. For Australia, Vietnam represents an increasingly important partner in Southeast Asia and a potential contributor to a more resilient regional security network.
The development is particularly significant because Vietnam is itself a claimant in the South China Sea, meaning deeper Australia-Vietnam military cooperation could strengthen the capacity of regional states to resist coercion and protect freedom of navigation without forming a formal anti-China alliance. The emerging pattern is one of distributed balancing: rather than confronting Beijing through a single bloc, regional powers are building overlapping defense partnerships that gradually make China’s military expansion more difficult to translate into uncontested strategic dominance.
