The emergence of new domains, such as autonomous maritime systems, undersea cables, and space, introduces fresh flashpoints for strategic competition. Concurrently, resource security and industrial resilience—particularly in critical minerals and semiconductors—remain central to the region’s geopolitical calculus. Efforts to establish normative frameworks and crisis-management mechanisms are more urgent than ever, given the complex interplay of threats.

China’s Accelerated Military and Technological Expansion: A New Paradigm of Deterrence and Risk

China’s military modernization continues at an unprecedented pace, fundamentally altering the regional balance of power. By 2030, estimates suggest China could possess up to 1,000 nuclear warheads, dramatically shifting deterrence thresholds and security calculations. Its conventional military capabilities have seen notable advances:

• South China Sea: Beijing’s artificial islands now host advanced missile batteries, anti-ship systems, and robust air defenses, challenging freedom of navigation and vital energy transit routes. Notably, China has deployed submarine-launched ballistic missiles (SLBMs) and autonomous naval vessels such as the ‘Ghost Shark’, an autonomous submarine designed to extend maritime reach and protect energy corridors amid rising tensions.
• Taiwan Strait: Chinese military drills have become increasingly provocative, involving simulated amphibious assaults, aircraft incursions, and cyber operations aimed at Taipei. These maneuvers elevate the risk of miscalculation, compelling U.S. and allied forces to maintain heightened alertness.
• Cyber and Space Capabilities: China’s deployment of grey zone tactics—including covert cyber operations and space-based surveillance and anti-satellite systems—continues to challenge traditional deterrence. Its focus on AI-driven military systems aims to enable autonomous decision-making, raising concerns about escalation control and rapid conflict onset.

Amid these developments, Chinese officials continue to emphasize “responsible development” of advanced technology sectors, asserting their actions are “grounded in sovereignty and stability”, even as international scrutiny on the AI and semiconductor races intensifies. The recent deflections during global forums underscore China’s attempt to project responsible stewardship while pursuing aggressive modernization.

U.S. and Regional Responses: Reinforcing Deterrence, Alliances, and Maritime Security

In response to China’s rapid expansion, the United States and regional partners are undertaking comprehensive measures:

• Missile Defense: Deployment of THAAD batteries in the Philippines, Aegis Ashore systems in Northern Luzon, and ongoing missile deployments across South Korea and Japan aim to shield critical energy and communication routes and deter Chinese provocations.
• Air and Naval Presence: The stationing of F-35 fighter jets across bases in Okinawa, South Korea, and Australia enhances interoperability and rapid response capabilities in flashpoints like the Taiwan Strait and South China Sea.
• Strengthening Alliances:
  • The Quad—comprising the U.S., Japan, India, and Australia—has intensified joint exercises, intelligence sharing, and maritime patrols.
  • Japan and India are expanding bilateral and trilateral security arrangements. Japan’s recent partnerships with Pacific island nations and patrol aircraft deployments to the Philippines exemplify an assertive posture aimed at maritime security and regional stability.
  • The U.S.-Philippines alliance has deepened, exemplified by initiatives like Seventy Years On: Philippines-Japan Security Ties in the Indo-Pacific, which highlights sustained defense cooperation and shared strategic interests.

Diplomatic efforts focus on arms sale protocols, crisis de-escalation, and confidence-building measures. For instance, Japan has publicly rejected Chinese accusations of militarism, reaffirming its actions as “grounded in a rules-based order.” Meanwhile, Taiwan continues to affirm its sovereignty, despite persistent Chinese military pressure.

The New Frontiers: Autonomous Systems, Undersea Cables, and Space

The expanding technological landscape introduces new strategic vulnerabilities and opportunities:

• Autonomous Maritime Systems: China has surpassed U.S. submarine production capabilities and heavily invests in autonomous surface and underwater drones, such as the ‘Ghost Shark’, aimed at extending maritime operations and undersea contestation. These systems promise reduced manpower requirements, improved survivability, and enhanced operational tempo.
• Undersea Cables and Communications: The strategic importance of subsea communication cables has surged, with recent intelligence revealing a “secret submarine game” where undersea assets are central to regional strategic dominance. Disruptions or sabotage could cripple communication and energy flows, escalating tensions.
• Space and Cyber Domains: China’s space-based surveillance and anti-satellite systems threaten U.S. and allied space assets, while cyberattacks targeting ports, navigation systems, and logistics hubs risk disrupting supply chains and economic stability.

Resource Security and Industrial Resilience: The Geopolitical Battleground

Resource competition continues to underpin strategic rivalry:

• Critical Minerals: China’s near-monopoly on nickel and cobalt—essential for batteries and electronics—has prompted nations like Australia, Japan, India, and Canada to diversify supply chains. The recent U.S.-Indonesia agreement aims to challenge China’s dominance in the nickel market, potentially restructuring global resource networks.
• Semiconductor Industry: Countries such as Japan and South Korea are investing heavily in domestic semiconductor manufacturing and shipbuilding capacities to reduce dependence on Chinese supply chains. The export restrictions on EUV lithography technology from firms like ASML have spurred efforts to develop domestic capabilities.
• Shipbuilding and Green Technologies: Australia is advancing sustainable resource processing and circular economy initiatives to bolster resilience. Japan’s focus on clean energy technologies reflects a broader strategy to address economic vulnerabilities and climate commitments.

Emerging Domains: AI, Cybersecurity, and Divergent Policy Trajectories

The rapid evolution of artificial intelligence introduces complex strategic challenges:

• China’s AI Drive: Focused on military applications, autonomous systems, and domestic surveillance, China’s AI initiatives serve as a cornerstone of its military modernization and governance.
• Cyber Threats: Recent intelligence indicates expanding Chinese cyber capabilities, including automated cyberattacks targeting critical infrastructure, port operations, and logistics hubs—posing risks to supply chain security and economic stability.
• Technological Sovereignty: Export controls on EUV lithography and other advanced technologies reveal vulnerabilities, prompting nations to develop domestic alternatives and diversify supply chains to safeguard technological supremacy.

On the policy front, climate and clean energy policies are diverging sharply:

• The U.S. emphasizes regulatory frameworks, private sector innovation, and climate diplomacy.
• China continues state-led investments in renewables and electric vehicle manufacturing, aiming to cement its leadership.
• These differences influence global trade, investment flows, and alliances, potentially leading to standards fragmentation and technological bifurcation.
