Go and critically read history books/articles/etc my friend, not only by the colonial regimes namely Spain, British, Dutch and France that have plundered the countries that you have just mentioned, and what names these areas are collectively called (yes they have their names) few centuries back before the dark colonial era started.

After that you probably know to whom the oil and fish belongs since these people have been fishing there for centuries. Truth and facts really matter but not your random opinions.
