The Evolving Defense Landscape in Southeast Asia: A Response to US-China Rivalry

Defense spending in Southeast Asia (SEA) has seen a steady upward trajectory over the past decade, driven by the escalating rivalry between the United States and China in the Indo-Pacific region. Countries in the region are investing billions of dollars to modernize their military forces, equipping them with next-generation tanks, warships, aircraft, and missiles. This military buildup is a direct response to the strategic rivalry between the two superpowers, which has intensified, especially in the past decade. In 2013, a notable increase in defense spending was observed across most Southeast Asian nations, including Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. These countries have either acquired or are planning to procure advanced military assets, including next-generation fighters, frigates, submarines, anti-ship missiles, and other sophisticated platforms. According to data from the International Institute for Strategic Studies (IISS), these nations allocated a total of $60.9 billion towards weapons procurement and defense research and development between 2013 and 2022, adjusted to constant 2015 USD, the observed increase in arms spending cannot be attributed to “arms race” but should be understood in the changing geopolitical context.

Southeast Asian Countries Navigating US-China Rivalry in the Indo-Pacific

In the 21st century geopolitical landscape, the U.S. and China are locked in a significant power rivalry, competing in both economic and military spheres. China’s strategic pursuit of global influence through initiatives like the Belt and Road Initiative (BRI), launched in 2013, has led to the expansion of its economic and military influence. This includes the Strategic positioning in critical geographic areas, with a particular focus on the SEA region. The U.S. Indo-Pacific Strategy, developed as a countermeasure to China’s growing influence and BRI, designates SEA as a “single most consequential region” for American interests.

Against this backdrop, even smaller SEA nations hedging can be fraught to be an engaging mitigating while maneuvering independencies in between military spendings vary depending on International Relations dynamics can be. However, international relations experts argue that while hedging may have been an effective strategy, the current intensity of Sino-US rivalry has made this approach increasingly challenging. For SEA nations, these challenges have led to a strong emphasis on acquiring military assets to enhance their readiness for potential conflicts. This strategic shift implies that a self-help policy has emerged as more ideal for SEA countries navigating this great power rivalry, and consequently the SEA countries are purchasing and upgrading, the whole set is military equipment, connecting to chain of future technology and contracts.

Identifying an Arms Surge: Race or Deterrent?

However, analysts caution against labeling the surge in military expenditure as an arms race. Recent SIPRI data reveals a significant increase in military spending in the SEA region, with expenditures rising from $34 billion in 2013 to $47.8 billion in 2023, but the extent to which it translates to an escalating regional arms race remains debatable and nominalised.they should enhance their security, and should not lead to arms race but to further development.
