There are several problems. Firstly, we don't have enough information about the situation in Asia. Also, we need both money and time in order to investigate.
Both, several and enough are quantifiers.
Both = two things or people.
Several = an imprecise number.
Enough = all that is necessary.

====='Several'=====
Note that we use several in formal contexts more than in conversation. For example:
There was a serious accident on the motorway and several people were injured.
There are several interesting books on this subject.
As a quantifier, we use enough before nouns:
We have enough tea.
We don't have enough coffee.
Do we have enough sugar?
But when it is an adverb of degree, we use it after verbs, adjectives and other adverbs:
I don't sleep enough.
He doesn't work fast enough.
This room is big enough.
You can ask Maria or George for help - they're both experts.
Both my son and my daughter are behaving badly today.
She dropped both her bags.
They visited several European countries.
I don't have enough money.
