Southeast Asia is one of the world’s most diverse and strategically important regions. Located between the Indian and Pacific oceans, it forms a natural bridge between East Asia, South Asia and Oceania. The region combines tropical islands, long coastlines, major river valleys, highlands, rainforests, volcanic landscapes, historic trading cities and some of the world’s most dynamic economies.

Geographically, Southeast Asia is traditionally divided into Mainland Southeast Asia and Maritime Southeast Asia. Mainland Southeast Asia includes Myanmar, Thailand, Laos, Cambodia, Vietnam and Peninsular Malaysia, while Maritime Southeast Asia consists primarily of the island and archipelagic countries of Indonesia, the Philippines, Brunei, Singapore, Timor-Leste and the eastern Malaysian territories.

The modern political and economic framework of the region is strongly associated with ASEAN — the Association of Southeast Asian Nations. ASEAN was established in Bangkok in 1967 by Indonesia, Malaysia, the Philippines, Singapore and Thailand. Timor-Leste became ASEAN’s 11th member on 26 October 2025.

Some areas experience considerably drier weather, although the timing varies from country to country.

Mountainous areas can have cooler climates, while equatorial islands such as those in Indonesia can experience rainfall throughout much of the year.
