Whats is the difference between 開発途上国 and 発展途上国?

Question

What is the difference in the usage of these 2 words?

I get the difference between 開発 and 発展 and my interpretation would be that 開発途上国 could refer to a developing country where the standard living conditions are low and are starting to improve, while 発展途上国 could refer to a country which is putting emphasis on infrastructure and other advancements.

Is one used a lot more over the other? Is there a minor difference in nuance?

Answer 1

They are identical. You can see several dictionaries redirecting 開発途上国 to 発展途上国. In that sense, 発展途上国 is somewhat more common.
