List of Southeast Asian nations with national flags and official languages.

Let’s go step by step to fill in the correct information for each country based on its flag.

We’ll match each flag with:
- Country name
- Joined (UN or ASEAN? Since most are ASEAN members, we’ll assume “Joined” means joined ASEAN unless otherwise noted — but actually, looking at context, this is likely about ASEAN membership since all flags shown are from Southeast Asian countries except Thailand and Singapore which are also ASEAN. Wait — let’s check: All 10 flags are of ASEAN member states! So “Joined” = year joined ASEAN.)

Actually, let’s confirm: The flags shown are:

Top row:
1. Thailand → Flag: red-white-blue-red-white-blue horizontal stripes
2. Brunei → Yellow field with black/white diagonal stripe and red crest

Second row:
3. Singapore → Red top half, white bottom half, crescent + stars
4. Vietnam → Red field with yellow star

Third row:
5. Malaysia → Stripes + blue canton with crescent/star
6. Myanmar → Yellow-green-red horizontal stripes with white star

Fourth row:
7. Philippines → Blue-red-white triangle with sun/stars
8. Laos → Red-blue-red horizontal stripes with white circle

Fifth row:
9. Indonesia → Red over white horizontal stripes
10. Cambodia → Red-blue-red horizontal stripes with Angkor Wat temple

All these are ASEAN members. So “Joined” = year they joined ASEAN.

Also need: Capital, Language(s), Currency.

Let’s fill them one by one carefully.
