A number of internationally-minded people follow 5 Flag Theory, whereby you diversify different aspects of your life (residency, banking, investments, etc.) across multiple countries to protect yourself against confiscation/default/etc. by foreign (or your own) governments.
I recently posted a Q&A How to open a bank account in Hong Kong remotely from the US? to explain an option for planting a "banking flag" without having to leave one's country of origin.
Is this question considered on topic for Expats.SE?
If so, I'll post another one for Mongolia (:
