Indo-Pacific The term denotes a maritime and continental expanse linking the Indian Ocean and the Pacific Ocean regions, encompassing shorelines, archipelagos, and hinterlands across South Asia, Southeast Asia, East Asia, Australasia, and parts of East Africa. It is used in strategic, ecological, and economic contexts by states, alliances, institutions, and scholars to describe interactions among major powers, maritime chokepoints, and biodiversity hotspots.

Definition and scope

Scholars and policymakers including Frank-Walter Steinmeier, Aukus participants, Joe Biden, Narendra Modi, Scott Morrison, and analysts at Center for Strategic and International Studies and International Institute for Strategic Studies use varying delimitations that often include Indian Ocean, South China Sea, East China Sea, Pacific Ocean, Strait of Malacca, and the archipelagos of Indonesia, Philippines, and Japan. Strategic doctrines by United States Department of Defense, documents from Ministry of Defence (United Kingdom), statements from Ministry of External Affairs (India), and white papers by Australian Department of Defence illustrate competing definitions tied to alliances such as Quadrilateral Security Dialogue and treaties like ANZUS. Academic treatments in journals from Asia-Pacific Center for Security Studies, Chatham House, and Brookings Institution contrast geographic, ecological, and security frames to set boundaries that sometimes extend to Horn of Africa, Gulf of Aden, and Hawaiʻi.

Geography and physical features

The region spans major maritime corridors including the Strait of Hormuz, Bab-el-Mandeb Strait, Strait of Malacca, Lombok Strait, and Bashi Channel, connecting basins such as the Arabian Sea, Bay of Bengal, Andaman Sea, Gulf of Thailand, South China Sea, East China Sea, and the Coral Sea. Prominent island groups include the Andaman and Nicobar Islands, Lakshadweep, Maldives, Borneo, Sumatra, Sulawesi, New Guinea, Taiwan, and Hawaiian Islands. Significant submarine features include the Java Trench, Philippine Trench, Mariana Trench, and continental shelves off Australia and India. Major rivers draining into the region include the Ganges, Brahmaputra, Mekong River, Yangtze River, and Pearl River, feeding deltas such as the Sunderbans and Red River Delta.

Ecology and biodiversity

Biodiversity hotspots like Sundaland, Wallacea, Coral Triangle, and the Great Barrier Reef host exceptional marine and terrestrial species lists catalogued by institutions including International Union for Conservation of Nature, World Wildlife Fund, and Conservation International. Iconic fauna across the region include Bengal tiger, Asian elephant, Komodo dragon, orangutan, giant panda, and marine species such as hawksbill turtle, green sea turtle, blue whale, and manta ray. Coral systems house genera studied by researchers at Scripps Institution of Oceanography and Woods Hole Oceanographic Institution; mangrove forests in Bangladesh and Myanmar buffer coastal erosion monitored by United Nations Environment Programme. Environmental pressures are documented in reports by Intergovernmental Panel on Climate Change and include coral bleaching on reefs off Palau and Fiji, overfishing in waters around Somalia and Vietnam, and deforestation on Borneo driven by commodities linked to markets in China and United States.

Historical and cultural context

Maritime routes shaped historical polities such as Srivijaya, Majapahit, Chola dynasty, Mughal Empire, and trading networks involving Polynesia navigators, Austronesian peoples, Arab traders, Portuguese Empire, Spanish Empire, Dutch East India Company, and British East India Company. Cultural diffusion occurred via ports like Malacca Sultanate, Aden, Calicut, Canton (Guangzhou), and Nagasaki, fostering religions and traditions including Hinduism, Buddhism, Islam, Christianity, and Shintoism across societies from Sri Lanka to Japan. Colonial encounters and conflicts such as the Anglo-Dutch Wars, Opium Wars, Sino-Japanese War, and Pacific War reshaped boundaries, while postwar institutions like United Nations and regional ties exemplified by ASEAN and Commonwealth of Nations influenced decolonization and cultural exchange.

Strategic and geopolitical significance

Naval chokepoints and forward basing have made the area central to strategies by United States Navy, People's Liberation Army Navy, Royal Navy, Indian Navy, Japan Maritime Self-Defense Force, and Royal Australian Navy. Contemporary security dialogues involve Quad, AUKUS, Five Eyes, and bilateral frameworks among France, Germany, Japan, South Korea, and Indonesia. Incidents around Scarborough Shoal, Paracel Islands, and Spratly Islands provoke disputes involving China, Philippines, Vietnam, Malaysia, and Brunei. Energy transit through pipelines and tankers links suppliers like Saudi Arabia and Qatar to consumers in Japan, South Korea, China, and India, while freedom of navigation operations conducted by United States Sixth Fleet and patrols by Royal Australian Air Force underscore strategic competition.

Economic and trade dynamics

Trade flows traverse ports such as Singapore, Shanghai, Hong Kong, Busan, Chennai Port, Port of Colombo, Port Klang, Laem Chabang, Sydney Harbour, and Port of Los Angeles for trans-Pacific connections. Regional value chains integrate manufacturers in China, Taiwan, South Korea, Malaysia, Thailand, and Vietnam with commodity exporters such as Australia, Brazil, Indonesia, and Chile. Agreements including Regional Comprehensive Economic Partnership, Comprehensive and Progressive Agreement for Trans‑Pacific Partnership, and bilateral deals between India and United Arab Emirates shape tariffs, services, and investment. Shipping lines like Maersk, COSCO, and Mitsui O.S.K. Lines and financial centers including Hong Kong and Singapore enable liquidity, while development financing from Asian Development Bank and New Development Bank funds infrastructure such as the China–Pakistan Economic Corridor and ports in Djibouti.

Regional organisations and cooperation

Institutional actors include Association of Southeast Asian Nations, South Asian Association for Regional Cooperation, Asia-Pacific Economic Cooperation, East Asia Summit, Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation, Indian Ocean Rim Association, and multilateral initiatives such as Belt and Road Initiative. Defense dialogues convene under forums hosted by Shangri-La Dialogue, ADMM-Plus, and Indian Ocean Naval Symposium; environmental cooperation appears in Intergovernmental Oceanographic Commission and conservation programs led by United Nations Development Programme. Financial and development coordination involves World Bank, International Monetary Fund, Asian Infrastructure Investment Bank, and regional development banks engaging member states from Kenya to Japan.
