How many ethnic groups are there in the ten ASEAN countries***?

Laos (68), Cambodia about 24 (unclear division), Myanmar (more than 135, very small division), Thailand (more than 30), Vietnam (54), Malaysia (more than 30 ), Singapore (three major ethnic groups, a typical country of immigrants from the East and the West), Brunei (more than 6), Philippines (more than 90), Indonesia (more than 200, mixed kind).

ASEAN countries have a history of colonization, a mixed population, and the entry of people from all over the world, coupled with the indigenous people themselves, ethnic relations are particularly responsible!

The local staff of the Department of Eurasian Affairs of the Ministry of Foreign Affairs probably can’t figure it out!
