Indo-Pacific Strategic Unity (IPSU): A Framework for the 21st Century

• The Indo-Pacific Strategic Unity (IPSU) is a proposed analytical framework to recognize the region as a cohesive system of trade, technology, energy, and military interests, rather than merely a collection of nations.
• IPSU is not a formal organization, treaty, or alliance; it serves as a lens to interpret existing geopolitical realities where global power is shifting.
• The region's heart is the Strait of Malacca, a critical maritime artery handling 22% of global trade and 29% of seaborne oil, with over 102,500 vessels recorded in 2025.

Geopolitical Actors and Dynamics

• China: Views the region as an essential lifeline for its industrial and resource security, investing heavily in ports, infrastructure, and supply chain integration to secure future corridors.
• United States: Seeks to maintain its role as a dominant power through a "free and open" strategy, protecting maritime routes and bolstering alliances like the Quad and AUKUS to contain Chinese influence.
• ASEAN: Acts as a central pivot with 690 million inhabitants and significant economic weight; ASEAN-China trade hit $772.4 billion in 2024 (20.1% of ASEAN total trade).
• India: Positions itself as a "hinge" power, balancing relationships with the US, Russia, and China to gain strategic autonomy and develop its own technological and military capacity.

Regional Hinge Points and Specialized Roles

• Indonesia: Provides demographic depth, mineral resources (nickel), and geographic connectivity between the Indian and Pacific Oceans.
• Malaysia: Serves as a vital maritime artery via the Strait of Malacca, necessitating a delicate balance between Western ties and Chinese investment.
• Vietnam: Operates as a critical manufacturing platform and a strategic actor in the South China Sea, skillfully managing relations with major global powers.
• Singapore: Acts as the "control room" of regional logistics, finance, and maritime security.
• The Philippines: Functions as a nerve center for US strategy due to its proximity to Taiwan and critical maritime disputes.
• Japan, South Korea, & Taiwan: Anchor the technological and military dimension through advanced semiconductor production, AI research, and high-tech manufacturing.

Broader Implications

• Non-coastal Actors: Countries like Mongolia (mineral hinterlands) and North Korea (nuclear destabilization) demonstrate that continental depth and military volatility are integral to the system.
• Infrastructure Influence: Development projects in nations like Laos and Cambodia act as a form of debt-based geopolitical leverage.
• European Role: EU nations, particularly France, maintain significant interests and naval assets in the region, seeking a role that balances US-China competition without imposing new forms of external tutelage.
