Question

which mordern countries were part of Indo China

Answer 1

HERE IS YOUR ANSWER :-

There is no official “Indochina,” so it’s whatever people think is meant by the informal or unofficial term. It’s made up of the Western roots for India and China, and has always referred in general to lands in between those two massive societies.

When there was - officially - French Indochina [Indochine Francaise] it consisted of just five entities: Tonkin, Annam, Cochinchina, Laos, and Cambodia. The first three of these constituted Vietnam, so, as Huong Nguyen correctly answered, “Indochina” is generally understood by area specialists today to consist of Vietnam, Laos, and Cambodia only.

I was surprised to see that he and other responders consider the term to include all of mainland Southeast Asia! I can’t say they’re wrong, exactly, because - as noted - there’s no official definition, but it’s not how I’ve learned to use the term in over half a century of studying and teaching Southeast Asian history. Language evolves; maybe that’s what the word is coming to mean to most people; but I myself would not say Myanmar (Burma) was part of Indochina, and if someone referred to “Indochina” I would not expect it to include Myanmar.
