U.S.-China Military Exercises in Southeast Asia: A Strategic Competition
10/15/2025, 11:16:41 AM
Overview of Military Activities
In 2025, the United States and China intensified their military exercises in Southeast Asia, reflecting their ongoing strategic competition in the region. The U.S. conducted war games with several Southeast Asian nations, including the Philippines, Thailand, and Vietnam, while China held its own exercises with Malaysia and other ASEAN countries. These military activities are part of broader efforts by both powers to assert influence amid territorial disputes in the South China Sea.
The U.S. aims to reinforce its security commitments and deter adversaries through these exercises. For instance, the naval exercise code-named Sama-Sama, which began on October 6, 2025, involved forces from the U.S., Australia, Japan, and several other nations, focusing on maritime security in the South China Sea. Meanwhile, China deployed over 700 personnel for the Exercise Peace and Friendship in Malaysia, emphasizing humanitarian assistance and disaster relief.
Regional Implications and Responses
The strategic competition between the U.S. and China has significant implications for Southeast Asian countries, which often find themselves caught in the middle. Collin Koh, a senior fellow at Singapore's Institute of Defense and Strategic Studies, noted that while Southeast Asian nations are increasingly integrating economically with China, they are simultaneously expanding defense and security engagements with the U.S. This dual approach reflects their desire to balance relations with both powers based on national interests.
Countries like the Philippines have shown a stronger alignment with the U.S., particularly in response to China's assertiveness in the South China Sea. Conversely, nations such as Cambodia and Laos have leaned towards China, complicating the regional dynamics. The varying threat perceptions among ASEAN members lead to differentiated responses, with some nations seeking to diversify their security partnerships to mitigate overdependence on either power.
Official Statements and Perspectives
China's Defense Ministry stated that Exercise Peace and Friendship aims to deepen military cooperation with Southeast Asian nations to address non-traditional security threats. In contrast, the U.S. Pacific Air Forces emphasized the importance of its relationship with Indonesia for promoting regional security and military modernization.
Koh remarked on the complexity of military interoperability among Southeast Asian nations, indicating that their defense engagements with the U.S. vary significantly based on shared interests and training complexities. He also highlighted that while regional countries are wary of China's territorial ambitions, they recognize the necessity of maintaining a robust relationship with the U.S. for security.
Criticism and Opposition
Critics argue that the U.S.'s unwavering support for Israel amid the Gaza conflict has strained its relationships in Southeast Asia. Public sentiment in countries like Malaysia and Indonesia has turned against the U.S., with many expressing frustration over perceived double standards in international law. This discontent could undermine U.S. influence in the region, as a recent survey indicated that more Southeast Asians would align with China over the U.S. if forced to choose.
What's Next
As both the U.S. and China continue their military activities in Southeast Asia, the future of regional security dynamics remains uncertain. The potential for joint exercises involving both powers is unclear, and regional countries will likely continue to navigate their relationships with both the U.S. and China carefully. The evolving geopolitical landscape will require Southeast Asian nations to maintain strategic autonomy while addressing their domestic development concerns.
