Southeast Asia is a transnational region in Eurasia comprising mainland and insular territories between the Indian Ocean and the Pacific Ocean, encompassing major cities such as Jakarta, Bangkok, Manila, Hanoi and Ho Chi Minh City. The region includes nation-states like Indonesia, Malaysia, Philippines, Thailand, Vietnam, Singapore, Myanmar, Cambodia, Laos, Brunei, and Timor-Leste. Strategic waterways such as the Strait of Malacca, the South China Sea, and the Gulf of Thailand have long linked local polities to empires, merchant networks, and colonial powers including Portuguese Empire, Dutch East India Company, British Empire, and Spanish Empire.

Geography

The region spans the Malay Peninsula, the Indochinese Peninsula, the Nusantara archipelago and the Andaman Sea coasts, featuring major rivers like the Mekong River, the Irrawaddy River, the Chao Phraya River, and the Cagayan River. Volcanic arcs including the Sunda Arc and mountain ranges such as the Annamite Range and Tenasserim Hills shape topography and biodiversity of islands like Borneo, Sumatra, Sulawesi, and Mindanao. Important urban agglomerations include Greater Jakarta, Metro Manila, Kuala Lumpur, Ho Chi Minh City, and Yangon. Regional climate is influenced by the Asian monsoon, the Pacific typhoon track, and oceanic currents such as the Equatorial Current.

Maritime trade routes connected premodern polities such as the Srivijaya Empire, the Majapahit Empire, the Khmer Empire, the Sukhothai Kingdom, and the Ayutthaya Kingdom to Tang dynasty, Song dynasty, and later Ming dynasty China, as well as to Chola dynasty India. European contact brought colonization by the Dutch East Indies, the British Raj administration of Malaya, the Spanish East Indies, and the French Indochina protectorates; decolonization after World War II saw independence movements led by figures like Sukarno, Ho Chi Minh, Aung San, and Jose Rizal's legacy. Cold War conflicts included the Vietnam War, the Malayan Emergency, and the Konfrontasi confrontation; regional diplomacy evolved through organizations such as Association of Southeast Asian Nations and summits engaging United States and People's Republic of China stakeholders.

States in the region exhibit systems from constitutional monarchies like Thailand and Malaysia to single-party socialist republics like Vietnam and hybrid democracies such as Indonesia and Philippines. Regional institutional frameworks include Association of Southeast Asian Nations mechanisms for diplomacy, security dialogues with ASEAN Regional Forum partners, and legal norms influenced by treaties including the United Nations Convention on the Law of the Sea. High-profile political events include national transitions following the 1997 Asian financial crisis, the 2004 Indian Ocean earthquake and tsunami response, and contemporary disputes over South China Sea claims involving People's Republic of China and claimant states like Vietnam, Philippines, and Malaysia.

Economic profiles range from high-income city-states like Singapore and energy exporters like Brunei to emerging markets such as Vietnam and Indonesia. Key economic sectors include maritime trade through the Strait of Malacca, commodity exports like palm oil from Malaysia and Indonesia, minerals from Borneo, rice production in the Mekong Delta, manufacturing hubs in Batam and Ho Chi Minh City, and services concentrated in Manila and Bangkok. Regional integration initiatives include ASEAN Free Trade Area arrangements, supply chain linkages with People's Republic of China, Japan, and South Korea, and infrastructure projects under frameworks such as Belt and Road Initiative and the Asian Development Bank.

Artistic traditions feature classical forms such as Khon dance, Wayang shadow puppetry, Apsara dance, and musical genres using instruments like the gamelan and the ranat. Literary canons include epics like the Ramayana adaptation in Indonesia, modern authors such as Pramoedya Ananta Toer, Jose Rizal's historical influence, and contemporary filmmakers recognized at festivals like Cannes Film Festival. Culinary identities reflect staples like rice cultivation, dishes such as pad thai, pho, nasi goreng, adobo, and spice routes traced to contacts with Arab merchants and Portuguese Empire influences. Sports and cultural diplomacy feature events hosted by Southeast Asian Games and participation in Olympic Games by national teams.

The region contains megadiverse ecoregions such as the Sundaland, the Indo-Burma biodiversity hotspot, and coral systems in the Coral Triangle encompassing waters near Philippines, Indonesia, and Malaysia. Iconic species include Bengal tiger populations in Sundaic region pockets, Sumatran orangutan and Bornean orangutan in Borneo and Sumatra, and marine megafauna along the South China Sea and Sulu Sea. Environmental challenges include deforestation for palm oil plantations, peatland fires linked to El Niño events, habitat loss from urban expansion in Jakarta and Manila, and transboundary haze affecting air quality across Malaysia, Singapore, and Indonesia. Conservation responses involve multilateral efforts with organizations such as World Wide Fund for Nature and initiatives under the Convention on Biological Diversity.
