The United States and Australia have announced plans to deepen defense cooperation and strengthen deterrence in response to China’s growing military and strategic influence across the Pacific.
U.S. Defense Secretary Pete Hegseth met with Australian Defense Minister Richard Marles in Washington on Wednesday, with both sides emphasizing the importance of maintaining a favorable balance of power in the Indo-Pacific.
Hegseth said Australia understood “the importance of maintaining a favorable balance of power in the region,” underscoring the strategic significance of the two countries’ longstanding security partnership.
Marles said the U.S. military presence in Australia was increasing and described the expanding cooperation as a response to what he called China’s unprecedented military buildup.
“The presence of U.S. forces in Australia is increasing,” Marles told reporters, adding that the two countries needed to strengthen deterrence and maintain regional stability.
“We need to make sure that we strengthen deterrence and the balance, so that we contribute to peace and stability in the region in which we live,” he said.
The announcements come as Washington and Canberra accelerate defense cooperation under the broader AUKUS security partnership and expand the U.S. force posture in Australia. Recent agreements have included efforts to accelerate infrastructure projects at Australian bases to support joint logistics, maintenance, storage and distribution capabilities.
The United States and Australia are also expected to deepen joint military activities as both governments seek to strengthen their ability to respond to potential security challenges in the Indo-Pacific.
China has criticized AUKUS, arguing that the partnership could contribute to an arms race in the region. Beijing’s growing military capabilities and expanding influence among Pacific island nations have nevertheless become increasingly important factors in U.S. and Australian strategic planning.
The latest measures reflect a broader effort by Washington and Canberra to reinforce deterrence while maintaining what both countries describe as a commitment to peace and stability in the Indo-Pacific.
