Some edits:

*
Capital city shares a first letter with the country you're trying to guess, not China. Sorry if this caused confusion!

**
There are a number of collections of islands, but several of them belong to other countries so they don't count towards this!

*x3 (formats into a page break if I type them out, sigh)
Didn't realize at the time of writing this that two southern SA countries share this description. You're looking for the one that reaches further south ;)

Hope everybody enjoyed!
