Indo-Pacific Deepens Defense Ties as Concerns Grow Over U.S. and China

C

ountries across the Indo-Pacific are accelerating military cooperation and strengthening defense partnerships as they seek to balance China’s growing military power while preparing for uncertainty over future U.S. engagement in the region.

The trend was on full display at the annual Shangri-La Dialogue in Singapore, where defense ministers and military leaders highlighted a growing push for regional security cooperation that extends beyond traditional reliance on Washington.

While U.S. Defense Secretary Pete Hegseth reassured allies that Washington remains committed to the Indo-Pacific despite its involvement in other global crises, regional leaders emphasized the need to build stronger security networks among themselves.

“We can do two things at one time,” Hegseth said when questioned about whether tensions in Iran could distract the United States from Asia.

Despite those assurances, officials from several countries acknowledged that concerns about shifting American priorities have encouraged nations to enhance their own military capabilities and expand partnerships across the region.

Regional powers expand security cooperation

Among the countries taking a more active role is Japan, which is positioning itself as a central hub for regional defense cooperation.

Japanese Defense Minister Shinjiro Koizumi said Tokyo aims to serve as a “connecting point” for security partnerships throughout the Indo-Pacific.

In April, Japan introduced the most significant overhaul of its defense export policies in decades, removing restrictions on overseas weapons sales and paving the way for exports of warships, missiles, and other military equipment.

“Japan will be even more proactive in defense equipment cooperation,” Koizumi said. “Our aim is to ensure that each country has the capabilities it needs and to make them available when needed.”

The Philippines has also expanded defense cooperation with Japan, Australia, Canada, and New Zealand as it faces growing tensions with China in the South China Sea.

Philippine Defense Secretary Gilberto Teodoro said regional defense leaders broadly agreed on the need to rapidly strengthen military capabilities.

He described the effort as a way of reinforcing, rather than replacing, America’s traditional security role.

“The commitment of the United States becomes more solid when more actors come in because there is a common threat,” Teodoro said.

Confidence in U.S. alliance remains strong

Despite efforts to diversify security relationships, many Indo-Pacific officials stressed that the United States remains the cornerstone of regional deterrence.

Singapore Defense Minister Chan Chun Sing said countries should pursue flexible partnerships with like-minded nations and create “coalitions of the able and willing” to address emerging security challenges.

Meanwhile, Canada and New Zealand are increasing their involvement in the region.

Canadian Chief of Defense Staff Jennie Carignan said Canadian forces are expanding cooperation with Japan and the Philippines through maritime exercises and cybersecurity initiatives.

New Zealand Defense Minister Chris Penk said Wellington is considering the purchase of Japanese and British naval vessels to replace its aging frigate fleet while exploring deeper cooperation under the long-standing Five Power Defense Arrangements involving Britain, Australia, New Zealand, Malaysia, and Singapore.

Although concerns persist about Washington’s long-term strategic focus, regional leaders largely rejected suggestions that U.S. commitment has weakened because of conflicts elsewhere.

For the Philippines, Teodoro said confidence in Washington remains intact despite U.S. involvement in the Middle East.

Similarly, Australian Defense Minister Richard Marles described the alliance with the United States as “absolutely fundamental” to Australia’s national security.

As China continues its military modernization and expands its regional influence, Indo-Pacific nations appear increasingly determined to strengthen both their own defence capabilities and a broader network of partnerships designed to preserve regional stability, regardless of future shifts in global power dynamics.
