How to learn the countries of Southeast Asia
Southeast Asia has eleven countries and two halves: five on the mainland, south of China, and six spread over the islands between Asia and Australia. Each half has an order.
Updated 6 October 2026
The mainland five
From west to east:
- Myanmar, the western one, against India and Bangladesh.
- Thailand, in the centre, with a long tail running down the peninsula.
- Laos, the only one of the eleven with no coast.
- Vietnam, the long S down the eastern coast.
- Cambodia, tucked under Laos, between Thailand and Vietnam.
The islands, and who shares them
- Malaysia is in two parts: the end of the peninsula below Thailand, and the north of the island of Borneo.
- Singapore is the island city at the very tip of the peninsula.
- Brunei is a small country on the north coast of Borneo, surrounded by Malaysia.
- Indonesia is the long arc of islands along the south, from Sumatra to the western half of New Guinea, including most of Borneo.
- Timor-Leste is the eastern half of one island in that arc, the one nearest Australia.
- The Philippines are the islands to the north-east, across the sea from Vietnam.
What gets mixed up
- Laos and Cambodia. Laos is on top and has no sea. Cambodia is below it and has a coast.
- Malaysia and Indonesia. Malaysia is the northern one, in its two parts. Indonesia is everything along the south.
- Borneo. One island, three countries: Malaysia and Brunei in the north, Indonesia in the south.
Practise it
Take one group at a time. Play it on Name it until the names come without thinking, then switch to Find it, which asks the harder question: given only the name, where is it? What you miss comes back sooner in Review, and what you know comes back less often, so a few minutes a day is enough.
