Top 'map' is just showing all of the countries that would fit inside China.
India and Africa are shown in the 2 'maps below', but are obscured by the banner. Each also covers a lot of other countries so If either of these was to be placed inside the China one, lots of the other countries would be missing.
If you open the article from the link I posted, you'll see/read/learn much more stuff. It is quite interesting.
