You have well written the expansion. You paragraph gives an insight, into some knowledgeable reading, correct grammar and good flow of words.

I have not practiced expansion much as yet, but from the top, I found certain areas where you can improve.

Such as very simple things like 'developed' country, is not spelled with a capital D. It is a common now, and if you want to emphasize on a particular work you may write it in inverted commas but don't put a Capital unless its a proper noun.

Rest is all good.

I will try to give my shot below
