Strategic Context: China’s Expanding Military Capabilities and Regional Ambitions

China's relentless military modernization continues to reshape the security landscape across the Indo-Pacific. Analyses from institutions like the International Institute for Strategic Studies (IISS) detail Beijing’s investments across multiple domains:

• Deployment of sophisticated missile systems capable of targeting regional assets and U.S. forces.
• Expansion of naval fleets, including aircraft carriers, submarines, and amphibious ships, to project power across contested waters.
• Advancements in space and cyber capabilities designed to gain strategic dominance and disrupt adversaries.

Further, China's sino-centric multilateralism, exemplified by the Belt and Road Initiative and the establishment of alternative international institutions, seeks to challenge Western-led norms and influence. Meanwhile, Beijing employs grey-zone tactics—such as covert incursions, economic coercion, and diplomatic pressure—in the South China Sea, near Taiwan, and in other contested areas. These actions elevate the risk of miscalculation, necessitating a robust U.S.-led response that combines deterrence, diplomacy, and resilience.

Recent statements from U.S. officials underscore that China’s challenge is considered the “defining story of the 21st century,” emphasizing the importance of a strategic, coordinated approach. The U.S. recognizes India's pivotal role in balancing China's influence, with recent analyses from the Pacific Forum highlighting New Delhi's strategic importance amid regional tensions.
